A small amount of commercial watercolor (tube) was added to a palette. An equal amount of water was added to the watercolor and a spatula tip of powdered lecithin was added and the mixture stirred well.
About five (5) drops of 20-25% (m/v/) dammar gum (resin) in either linseed oil of C16-C-20 alcohols (Sassol North America) was added and the emulsion well stirred. The paint applied directly to bristol paper afforded a light impasto effect and a bristle brush was used.
I am studying the drying time at 20 deg.C. I will report my findings.
