Illuminations/ drawings:
Life-like (65v): There are some who paint in a life-like manner on oiled paper and if they do not complete their work in the first go, they put their paper with its unfinished portrait in water so that it will not dry.
Painting large figures (65v) You must position your charcoal at the end of a stick in order to make your first drawing from a distance because up close, you would not be able to judge the proportion very well, as you would from a certain and sufficient distance. Also, when you paint up close, hold the longest charcoal you can as if you were holding it with your fingertips. For in this way you will acquire the trait of an artist, and your hand will be made nimble.
Note (left-middle): Illuminators painting on paper distemper their colors with gum and mix it with a bit of soap to make them run better.
Layer of gold leaf on parchment or paper (10v): Make a very transparent starch glue (colle d’amydon) with little body. And apply.
Brown gold layer on paper (29v): Prepare your underlayer of starch soaked in water and your gold will turn brown very well. Clear starch water laid down on paper, then dried, and so by three times, is a good base for brown gold on paper and is not thick.
Materials Needed:
Oiled paper
Water
Charcoal
Pigments
Gum Arabic
Soap? (Need to research what kind of soap would be used)
Gold leaf
Parchment
Paper
Starch glue
Starch
Safety Considerations:
GUM ARABIC
Common name: Gum Arabic
Hazard statements from MSDS:
- Causes skin irriation
- Causes serious eye irritation
- May cause allergy or asthma symptoms or breathing difficulties if inhaled
- May cause an allergic skin reaction
- May cause respiratory irritation
Safety Precautions:
- Wear gloves, goggles, and lab coat; possibly also respiratory mask
- Work in a well-ventilated area (like fume hood) and/or wear mask
- Don't ingest
- Cover all work surfaces with newspaper
- Contaminated clothing should not be allowed out of the workpolace
Disposal and cleanup:
- Do not allow any water from cleaning procedures to enter drains
- Check with lab to make sure containers containing gum are disposed of properly (if emptied)
- Take care not to contaminate surfaces; dispose of newspapers/plastic drop cloth covering work area in appropriate containers
SOAP
Need to research what type of soap is meant in recipe; follow any safety considerations for ingredients of soap.
PIGMENTS
Will need to research the safety protocols/procedures for specific pigments if using any potentially harmful pigments (i.e. verdigris, lead white, etc.) in illumination experiments
Experiment protocol:
Make sure all experiment participants are wearing appropriate personal safety apparel (lab coat, gloves, goggles) before beginning any experiments. Set up workstation, storing Gum Arabic in fume hood if not in use. Cover work surfaces with newspaper or plastic. Be sure to document stages of experimentation with camera and field notes. When experimentation is finished, clean work area following above safety procedures.
Paper:
Thick Paper (81r): One must take some paper from Florence, which is the finest, and crush it and and soak it several times and change the water every day, that way it does not smell bad. And after having moulded it into the hollow, put a cloth over it, and from the back side, rub the back of your paper with a sharp piece, as if you wanted to polish it and it will mould very neat. Then glue some cloth from the back side with strong glue.
Mouth glue (7r): is made of parchment scraps and used to glue paper or similar things without fire, by wetting it with one’s mouth.
Note:It is whipped and left to soak in white wine for one night, then melted over a low heat. Others soak it in spirits.
Whitening paper (12r): >The whitest and thinnest is the best. And when the hollow mold is quite clean, as when it is made of sulfur or baked cimolee, [the paper] comes out very clean. You can apply a layer or two of white, with a border of gold, to imitate alabaster. And after applying the white you may burnish it with a tooth. Yet in order for it to take burnish you should soak the lead white with egg white and fig peel. Or better still, varnish your work with white varnish. Also while you are molding with paper, as it starts drying, burnish the back of it with the tooth.
Materials Needed:
Paper (from Florence – need to research whether Florentine paper has specific properties here?)
Water
Cloth
“Sharp piece”
Glue
Parchment scraps
Sulfur
Lead white
Egg
Fig peel
Safety Considerations:
No hazardous materials detected in paper recipes. Follow general lab safety guidelines and wear personal safety apparel when working in lab.
Experiment Protocol:
Make sure all group members are wearing appropriate personal safety gear (lab coat, gloves). Set up workstation with all materials, and be sure to document experimentation with field notes and camera throughout. After experimentation, clean area thoroughly, return all materials to their appropriate locations in the lab, and follow all lab protocols for material disposal.
Written text:
Erasing a letter (46v): Dip a writing quill in fresh and good oil of sulfur and, thus, retrace all the letters with the dipped quill and they will disappear from the parchment.
To write as easily from the left as from the right (19v): Write in the best manner possible with some well gummed ink on as many cards as many words you want to write and when your letter is full of ink, apply your paper and rub with a tooth the back of the cards.
Making à jour letters in paper (46v): If you write or trace something on the paper and heat it soon after, and immediately it will become black; then by rubbing with a sponge, the letter will be cut out because it will be burned. Urb. Or retrace the letter with a wiped quill.
Gold lettering on paper (8r): Write with fig tree milk then let it dry a little, afterwards apply the gold in leaf and, once quite dry, rub with linen and only the lettering will hold.
Mathematic figures without a ruler or compass (19v): you know how to draw a circle with a quill and otherwise with your right thumb nail and your folded big finger if you don’t have any ruler, fold a paper sheet in five or six folds to use it. And if you want to draw a column, arch, oval, cartouche correctly without a compass, fold your paper so the fold is a straight line from which you draw within the relevant distance a point or a line and fill it with some ink. Then fold again the paper and rub it on its reverse and it will stamp whatever you have made. In that way, A is the line without ink made by the paper fold, B is the line you have drawn, C is the stamped one.
Writing without ink (46v): Write with oil of sulfur and heat [it], and the letter will become as black as this one.
Oil of sulfur for the writer (46v): If the writer wants to quickly clean his quill of the thickness of the ink which dried on it, he only has to dip it in oil of sulfur, and immediately it will be white and clean.
Materials Needed:
Quill
Oil of sulfur (sulfuric acid)
Parchment
“Gummed ink” – gum arabic + ink?
Paper
Heat source
Sponge
