In the course of my job I get the pleasure of treasure hunting through old historical texts on painting materials and methods. For an established paint-geek like myself, this is pure heaven, especially when uncovering an insight or finding a gem to be gleaned from all those past experiences. Every now and then, however, I come across something that is – shall we say – of a more curious nature that can certainly raise an eyebrow or two. The following is one that caught my eye the other day and thought I would share. It is an excerpt from Robert Dossie’s Handmaid of the Arts published in 1783, and found in Storm, A. “Eighteenth Century Paint Materials And The Painters Craft As Practiced In Louisbourg” 1982, (Cape Breton, Nova Scotia Canada) :
“To make a drying oil to make any color that is mixed with it, dry quickly:
Add two ounces of litharge of lead to a quart of linseed oil (though some use red lead) powdered very fine, and boil it for near an hour in an earthen pan, or till the oil be grown fat, or almost of the consistence of molasses, then set it on fire with a lighted paper, keep it stirring while burning, which need not be above a minute or two, then put out the flame, and let it stand till it be thoroughly cold, and that the litharge has settled well to the bottom; then pour off the clear oil, and put it in a bladder, close tied up for use. “
Well, some things in the 18th century are really best left in the 18th century.
And I hope it goes without saying, don’t try this at home. Or anywhere else for that matter.
