Buckthorn berries, Yellow Experiment(s) 2

I tried to begin to follow another source to produce yellow.  I was working from Merrifield's Bolognese Manuscript, De Fiendis Viridibus again!  This book is so big, I'll never run out of possibilities. :D I will, ultimately, have to read it cover to cover.  I know I'm missing her details about general color production, opinions and her references.


Merrifield pg 428
The last ripe berries from Shana's New Hampshire Buckthorn bushes, about 30g, only yielded about 20 drops of juice so that attempt was unsuccessful.  At the end of September I found Buckthorn across the street in Saco.  I acquired the appropriate permission and went picking berries.  Someday I need to find an identification key for these Rhamnus spp bushes.  These berries seem plumper and larger, it must be a different variety or maybe they're just really ripe?
The 189g of big, juicy berries were manually squished with gloved hands and squeezed through cheesecloth to yield about 63g sludgy juice that I closed in a jar.
With fall archery events we were busy for more than the next month.  The juice sat closed in the jar for almost five weeks.  That was longer than the instructions indicated but I'm a volunteer... busy with being an archery safety officer and regular life activities when I'm not doing scribal or other Arts&Sciences projects!
I noted that when I finally opened the jar that the juice was definitely fermented and smelled like wine.
Athena Thickstun's blog helped me define that a 'fiasco' of wine is 2 liters.  One quarter of that would be 500g.  I didn't need that much so I made a smaller batch. Taking 200g distilled water I added a teaspoon of lye, K2CO3 (<1g on the kitchen scale that I had access to since I flooded the little one I had been using).  Then I added about the same quantity of alum (aluminum sulfate Al2(SO4)3. which resulted in immediate fizzling.  [I have since found out that that is the wrong alum.  Next time I will use rock alum which I have learned is KAl(SO4)2.]  As instructed I heated it in my corning ware sauce pot on low for the time that it took me to recite the Our Father prayer in Latin:
Pater noster qui es in coelis sanctificetur nomen tuum.
Adveniat regnum tuum. Fiat voluntas tua sicut in coela et in terra.
Panem nostrum quotidianum da nobis hodie.
Et dimitte nobis debita nostra, sicut et nos demittimus debitoribus nostris.
Et ne nos inducas in temptationem.
Sed libera nos a malo.
Amen.
Adding the prepared lye/alum/water to the jar of juice there was an immediate color change of the reddish juice to a yellow/green liquid.

"Very fine white earth like the fellmongers use" is defined in Alexander's glossary in the Dover edition of Merrifield's treatises as lime.

In the spring of 2016 I was able to come back to this experiment.

I found pulverized (vs. pelletized) lime at one of the big box garden centers.


Speaking to Randy Asplund about it again he advised that I was basically making a lake pigment and elaborated on the volume of a mezetta, "In Florence the mezzetta was equal to 0.7613 liters."  I recalled that I had made a smaller volume and not very accurately measured the lye and water in the fall because my little scale had died the quick death of drowning in a different experiment.  Water under the bridge; I'll know the correct mezzetta volume next time!  Regardless, this might have worked anyway.

Back to creating a lake pigment... Cool!  I have never made a lake.  The Materials and Techniques of medieval painting talks about brazil lakes:
Sometimes the decoction of brazil wood with alum was precipitated with chalk, and a more opaque, pink, rose colour was produced by the resulting admixture of calcium sulphate to the alumina lake.  Sometimes, in England, instead of adding chalk to the solution, a chalk stone was hollowed out, and little holes were made in the bottom of the hollow, and the hot alum solution coloured with brazil was poured into the hollow of the chalk.  The reaction between the alum and the chalk took place at the surface of the chalk stone, in that case, and a crust of semi-opaque brazil lake was formed in the hollow and in the little holes.
When lakes were made by precipitating the alum solution with the chalk, the calcium sulphate was formed automatically along with the lake, in intimate combination with it.  Sometimes brazil lakes were given some opacity by adding opaque substances to them at the moment of precipitation, and even after.  When white lead was used, as it sometimes was, it had no other effect than to give a little substance to the lake, to make it a little less transparent, and to develop the rosy colour.  when marble dust and powdered egg shells were added to the newly formed lakes, or introduced along with the precipitating agent, they probably had the further effect of controlling the colour produced by reacting chemically with any excess of alum which might give a brown cast instead of the desired rose.  In all these cases the brazil colour was mordanted upon the white material, whether calcium sulphate, or an excess of chalk, or white lead, or marble dust, or powered egg shells.  The white substances were, so to speak, dyed with the brazil; and the pigment so formed was different from a mixture of a finished lake with the white pigment. (Thompson 119)
So, since I'm making a lake, I tried both crushed eggshell and pulverized lime.  I took about 10 g of each and pipetted off about 5 g of liquid from the jar into each material.  The eggshell is probably not pulverized enough to paint with.  I wonder if I can mull it or crush it down and use it anyway.  And just maybe add more of the buckthorn/aluminum sulfate/lye juice after "in order that it may become more beautiful and of a brighter colour" (Merrifield 428)

Buckthorn yellow.  Ripe buckthorn berry juice with lye and aluminum sulfate with crushed eggshell.

Buckthorn yellow.  Ripe buckthorn berry juice with lye and aluminum sulfate with pulverized lime.
This experiment produced beautiful yellows!  Some day I'll try to paint with them.  I bet you can paint with the plain juice like with the sap green as a transparent glaze.  I wonder if you can make a green lake with that juice with lime or eggshells too.  Anyway, yay yellow!

Mr. Asplund advises that this yellow lake can be produced in the same way from green berries too.  Awesome!

Dyeing skins green with Buckthorn berries, ripe berries Experiment 3

I was excited to try dyeing some leather green using another recipe from one of Mary Merrifield's translated Original Treatises.  "Someday", I secretly dreamed, "Mistress Isabel Chamberlaine might make my wish a reality and take me as an apprentice.  I'll need a green belt!"  Spoiler alert... I was apprenticed at Birka!

Adrienne's Experiment steps:
Research
Collect materials
SAFETY FIRST... 
 Suit up with nitrile gloves, goggles over glasses and dust mask!

Back to the medieval inspiration for the dream for the need of a green belt...

Bolognese MS De Tintis ad Tigendum Pellum (Merrifield 558)
I wasn't sure what a medieval "boiler" was.  Not wanting to contaminate any of my food-grade cast iron pots, I used the same corning ware sauce pan as in Experiment 2.  I used another 100g of the ripe buckthorn berries from Shana's.  They had a few leafy bits but I wasn't willing to arduously pick that out and I didn't want to contaminate my berries by rinsing them.

Combining the ripe berries with the same quantity, by weight, of organic, unfiltered cider vinegar (Bragg brand) I continued to follow the instructions.  I put it on the simmer burner of my gas stove on low for fourty-one minutes.  When the berries and vinegar had "boiled a little" I took it off the heat.  I let it cool a bit then poured it into a washed, secured square of linen over a clean jar then squeezed the juice out into the sealable glass jar.

When I tried to paint it, the shinier 'outside' part of my leather just achieved a blueish gloss and the sueded part still blueish.  Maybe it's just because it's a modernly prepared piece of leather?  

Painting the first three experiments out on a small piece of leather, the only one that's green is Experiment 2.



I painted them out again onto what turned out to be chromium tanned moose leather six months later with pretty much the same results.

                                              Left 3/18/16                Right 9/15/15
                                         Experiment 1                   Experiments 3,2 and 1  
                                         Experiment 3
                                         Experiment 2

Tomorrow I'll try again on Vegetable tanned leather from Birka.

Sap Green 2 from Buckthorn berries

This is the continuation of my research on trying the medieval paint recipes for Sap Green from Buckthorn.

Once I figured out what Buckthorn berry bushes looked like I began to see them everywhere.  Consequence?  More experiments!

I visited my good friend Shana Clark in New Hampshire to raid her local Buckthorn bushes in early September.  They were growing in a more open area in more sun than the ones in the first experiment.  The branches were full of berries, mostly ripe and dark and with a few green.  The next day I sorted them into 53g of green and 341g of ripe berries.

I had already experimented with the Iris Green paint recipe from De Arte Illuminandi with pretty results so I was excited to put the recommendations for Buckthorn to use.

De Arte Illuminandi, pg 7
And it's note: 

De Arte Illuminandi (Thompson and Hamilton 43)

Then the recipe:
De Arte Illuminandi (Thompson and Hamilton 7)
Adrienne's Experiment steps:
Research
Collect materials
SAFETY FIRST...
Suit up with nitrile gloves, goggles over glasses and dust mask!

I took 100.00g of ripe buckthorn berries and crushed them with a plastic fork.

In a glazed porcelain (corningware) sauce pan I mixed 11.60g of lye (K2CO3) with about 100g distilled water.  Adding 5.05g of alum (aluminum sulfate) resulted in immediate bubbling.  The reactions at this point have raised the temperature a little to 80F.  Warming the mixture on a simmer burner on low, I hoped to dissolve more of the alum.  After about ten minutes the bubbling had mostly stopped, the temperature had risen to 120F and the solution had a pH of 6 with a milky appearance.  After heating it up to encourage the alum to dissolve and losing a little in the sink when I poured it into the jar with crushed berries, the total weight of the solution had decreased to 87.07g.  There was also a little residue left in the pan.

I mixed the solution into the berries with the same plastic fork I had used to crush them.  The next day I found the solution bubbling out of my pint jar!  I got rid of the beautifully green paper towel beneath my jar and put it in a glass bowl.  As the recipe directs I "let them stand so, out of the way, for three days".  After they had rested I used a clean square of linen to strain the juice into another jar.

The next week I painted it out!  What a beautiful green!

Medieval Mappae Clavicula Elderberry Paint Recipe

Last year I posted some medieval recipes for blue paint from elderberries here.  And the testing of it as blue paint here.

I am excited to expand the post to include pictures of a manuscript of the Mappae Clavicula, one of the medieval recipe sources I used.  The manuscript is held at Rakow Research Library which is part of The Corning Museum of Glass.   The entire manuscript can be downloaded from their website here.

This picture is provided by the courtesy of the Rakow Research Library, The Corning Museum of Glass.

This table of contents entry is toward the beginning of the parchment leaves.  The numbers were penned in red ink probably after at least most of the book was written. We'll see the red ink again later.

To me the latin content entry reads:
lxxxiii
Indicum colorem facere.
Which can be translated as
eighty-three
To make an indigo color.
In the manuscript we find the page with the description of how to make the blue color.  Note the different colored inks used again.  This time perhaps to designate titles versus instruction.

This picture is also provided by the courtesy of the Rakow Research Library, The Corning Museum of Glass.

Mostly trusting and heavily relying on the Latin edition found on Corning's website here, on page 28 which can be accessed by typing in 32 of 70 pages in the downloadable pdf, the abbreviated latin probably reads as:
Indicum colorem facere.  Succum de ba(c)cis ebuli collige et diligenter sicca at solem de hoc quod remanserit fac pastillos cum parvo aceti et vini et utere 
According to a magazine I interlibrary loaned, Transactions of the American Philosophical Society held at Philidelphia for promoting useful knowledge, New Series Volume 64 part 4 written by Smith and Hawthorne in 1974 in the article "Mappae Clavicula, a little key to the world of Medieval Techniques", it can be translated as:
97. Making indigo pigment.  Collect the juice of dwarf elderberries and dry it thoroughly in the sun.  From what remains make pastilles with a little vinegar and wine, then use it.
I would have translated "Indicum color facere." as "make indigo color" but high school Latin class was a long time ago now. Perhaps the disagreement with what number of the recipe has to do with either different manuscript versions, mis-translation (probably by me, I'm pretty new at deciphering manuscripts) or the numbering being added either after the book was done by the original scribe or by a different scribe, perhaps even at a different time. I have not finished reading all of the resources on the internet about Mappae Clavicula; maybe I'll eventually find more theories about the differences but I wanted to share the great references provided by the Corning Museum of Glass and it's Rakow Research Library. Go check out that manuscript; it's great!

Sap Green 1 from Buckthorn berries, medieval paint recipes,

There are many medieval sources with recipes for Sap Green, the beautiful paint and pigment used to provide green in medieval miniatures and to dye skins green among other things.

My first Experiment to produce green with Buckthorn was one from Mary Merrifield's Original Treatises, a 15th century recipe from Bolognese MS De Fiendis Veridibus (Merrifield 426)

I picked the berries in August in Westbrook, Maine.  Here's that first recipe:
Mary Merrifield's Original Treatises pg. 426
As the recipe suggests the day after picking the berries I combined about fifty grams each of ripe berries and Hannaford white vinegar of 5% acidity in a glazed sauce pan and heated it at gas mark two on the simmer burner of my stove.  At two minutes I noted that it was steaming, at four forming bubbles.  Five minutes in it was spattering so I turned it down to low and simmered until the weight of the mixture had reduced by about half which took about thirty-five minutes.  I poured it all into a square of washed clean linen secured over a canning funnel over a glass jar then squeezed as much liquid as I could into the jar.  The liquid looked dark purple.  Several days later I painted it out.

The alum water I used in the following paints is pure alum, Aluminum Sulfate, Al2(SO4)3, and distilled water in a 1:10 ratio.  This should make an acidic solution.

"A" consisted of a drop of the buckthorn and white vinegar juice as well as Winsor Newton Gum Arabic.  It painted out blue then turned green the next day.
"B" a drop of the vinegar-buckthorn berry juice, one drop of the gum water and a drop of alum water.  It painted out green immediately.

A on the left, B on the right.  Still wet B is already green.

"C" is the same as A in a clam shell, it painted out red purple-y and turned green by the next day.


"D" is C, juice and gum in a clam shell, with a drop of the same 1:10 alum water in B and like B it painted out green and stayed green.



Ultimately there will be an updated picture of after all of them turned green and one of my notes too!

And more experiments:

Sap Green and yellow from Buckthorn berries


Several important books talk about Sap Green, a medieval and renaissance pigment used in Book illumination among other things.  This year I had a mission to make some of this paint using the techniques and methods medieval paint makers may have utilized.

First I made note of all the different recipes for sap green and then had to find the materials these paint makers talk about.  

In De Arte Illuminandi, an anonymous 14th century treatise, translated from the Latin by Daniel Varney Thompson, Jr. and George Heard Hamilton in 1933, the author talks about several greens including buckthorn berries. (Thompson and Hamilton, pg 6-7)  

Buckthorn Berries are further described by the translators in their note "For the identification of these prugnameroli as buckthorn berries (Buckthorn = It. spincervino, spino gerbino), fruits of the varieties of buckthorn, Rhamnus, see Cennino ed. cit., II, p 32, n 1. (Thompson and Hamilton p 43). 

Further reading of this note explains the etymology of Sap Green which has nothing to do with the juice or sap from the plant and berries but how it may have been stored. 
"the color known in English as 'Sap Green,' the Italian verde di vescica (so called because the inspissated juice was preserved in bladders), the Saffgrien of Valentine Boltz, who specifies ed. cit., pg 75" the time of year "therefore, in Alsace, the color came out yellow if the berries were gathered in August, and green if they were gathered about the middle of September, we may probably assume that the quality of green yielded by these Rhamnus fruits was not entirely definite." De Arte Illuminandi pg. 29

So, Sap Green and yellow from the Buckthorn...

It took me what felt like forever to find Rhamnus spp. berries.  I searched the fields and ditches nearby, went to "Buckthorn Lane" in my local neighborhood in Saco, Maine; I found other trees with other fruits but no Buckthorn!  Finally someone said 'look for tall trees, usually somewhere wet' so I went back to my stomping grounds as a teenager in Wesbrook, Maine and found spindly trees in what used to be a protected wetland for turtles.  "This?!  Is this it?!" I begged my friends to confirm cell phone pictures of my find.  


The leaves look right from the plant books, the berries are dark and the bush was spindly and taller than I might have guessed, growing somewhere wet.  "Yes!", they chorused, "that looks right, try it!"

So I tried some of the recipes and will post them soon.  Sorry it's taken so long!

Iris for pigment References


These are the references I used during my iris experiments.  I tried to recreate medieval paint an pigment recipes using the iris from my garden.  Those experiments can be found here and the paint results with them here.

You may note that they call them 'blue lilies' with astonishing regularity.  This will make noticing other references easier.

 A 14th century anonymous treaty De Arte Illuminandi pg 6-7

"(Green) may be seen... in blue lilies, which are called iris, and yet are changed into a very pure green color by treatment.
The color is made from these lilies as follows.  Take these fresh flowers in the springtime when they are blooming and pound them in a marble or bronze mortar and squeeze the juice with a cloth into a glazed porringer.  And in this juice soak other linen cloths, clean and soaked, once or twice, in a solution of rock alum and dried.  And when the cloths are thoroughly saturated with the juice of the lilies in this way, let them dry in the shade, and keep them between the leaves of books; for a very lovely green, suitable on parchment is made out of this juice, made in this way by combining it with gallarino.  And note that after the cloths are dry, if they are again soaked in this juice and dried, they will be better." pg. 6-7


Daniel V. Thompson's  The Materials and Techniques of Medieval Painting

"The chief rival of sap green in late medieval manuscript pianting was iris green. This was made from the juice of iris flowers, sometimes mixed with alum and thickened, like sap green, but more often prepared as a clothlet. Bits of cloth were dipped into the juice of iris flowers and dried, again and again, until they contained a sufficient quantity of the color." pg. 171


Mary Merrifield's Medieval and Renaissance Treatises on the Arts of Painting 

"Lily or Iris green (verde giglio). --This pigment was sometimes prepared for use by dipping piece os linen (pezzette) into the juice and then preserving them dry." pg. ccxix

Lady Brynhildr Ansvarsdottir's AoA


Assignment: Award of Arms for Brynhildr Arnsvarsdottr
Words: Mistress Aneleda Falconbridge
Calligraphy: Lord Alexandre Saint Pierre
Illumination: Lady Adrienne dEvreus




Scroll Story:

I received the proposed assignment for one of my fellow queen's guards from the EK signet.  The write-up was brief and the contact for more info was the king himself, Brennan Ri.
When I reached out to him he told me great tales of this fearsome, fearless yet gentle woman warrior who was his man-at-arms.

The weekend after speaking with him Alexandre and I went camping at Endewearde's Hunt.  I spoke of the assignment to the breath of fresh air and silver-tongued inspiration that is Aneleda Falconbridge, asking if she knew of Brynhildr.
"I know her well," said Aneleda, "She enjoys it when I sing to inspire her passion for battle and she has told me so."
At least it was something like that. ;)  I am not a bard!  I was excited that Aneleda had had contact with Brynhildr and asked if she would help me write the letters that would honor her with an Award of Arms.  Aneleda said yes!  She wrote these beautiful words for Alexandre Saint Pierre to pen:
In the Eastern land ruled great King called Brennan with his wife Queen Caoilfhionn  Brynhildr Ansvarsdottir was fostering there and was sent to guard the land's most precious treasure, the Queen. Brynhildr was called to the Crown Tournament in the holdings of the Hersir of Bergental. Because she had served with joy and abundance, she was given the right to bear arms, ____________________________________ and take the title Hefdharkona. It was the fiftieth year, on the seventh day of nóvember, after Gormánuður but before Ýlir. The King had his poet and scribe make word-gold for her to be read and seen that day.

The linden of the battle-wall 
lifted her slender hands
to join the Njords of swords.
Shield-bearer now arms-bearer
Silver-dressed goddess of the raven-field
You are worthy to hear an ode*
war-valiant one, wrought for you*
 King Brennan and Queen Caoilfhionn made their names on it.
*these two lines are from the saga of Hallfred Troublesome-Poet (trans. Diana Whaley)

While waiting for words I decided on inspiration.  I don't yet know the full meaning and significance of long ships in Viking art but they seem abundant and striking.    


This one is from an Anglo-Saxon Chronicle in a section about stars.  I had help figuring this out and more explanations about it from Michael Rupert and Sari Csollany who shared this blog on the Book of Faces.

In closing it was inspiring working for Brennan Ri more directly than usual and I am grateful for the contributions of all of the scribes and researchers who helped me pull this one together!  Special thanks to my wordsmith, Mistress Aneleda, just before her elevation, and to my beloved beau and calligrapher, Lord Alexandre.
