Keep pan set closed. Add more drops of emulsion before painting again.
Great for a class and artist experimentation at all levels! I am using the cheapest pan set I own. As you know, some sets are of a very high quality.
I research modified linseed oil ( drying times) , but this can be done on limited budget and space.
When Henri Matisse was recovering from an illness, his mother gave him a pan of watrercolors. he became..... Matisse!
Artists often recall fondly starting art with these humble sets!
I will upload more infor and images as I progress!
