In research for the second book in my Culper Ring Series, Whispers from the Shadows, I had a heroine in 1812 who was an artist...and who had to mix her own paints. When writing it, I dreaded trying to find information on what it was like to create her own pigments back in the day, but I was pleasantly surprised to find a book from the 1700s that told me all about it!
As for colors, there can be either pigments or fluids. Pigments must be mixed with a fluid. Fluid-colors are few and only used for watercolor. So any oil pain is going to require a pigment. The equipment required to make them is extensive--you would need three separate furnaces for subliming the three different primary colors (subliming is the process of heating a solid until it turns into a vapor that, upon cooling, becomes a solid again, bypassing the liquefaction stage--this is a means of separating substances or purifying them), coals, boilers, filters, boards for drying...
But what I found very intriguing were the ingredients used for the pigments themselves. Ingredient lists include things like ground-up beetles. Urine. And processes often involve packing things into the ground with dung.
The directions in this book are incredibly specific, down to how thick the metal needs to be when building your furnace to the precise measurements of cross-members to what fabrics you can use to hold each different color.
It wasn't an easy task, to be sure--and the author found it a very sad occasion to note that the French were far ahead of England and her Colonies in devising methods and producing exceptional paints. Through this book, he hoped to alleviate a bit of that distance and make paint-production attainable for the British artist.
And we can be glad they did, and that we have such masterpieces to remember the period by.
