This is a newspaper advertisement from Connecticut in 1807. Note that the paint colors come in hogsheads, barrels, casks and cases, etc., as paint in the nineteenth century was sold by the pound. It was therefore a powder pigment which was made into paint by adding linseed oil, turpentine and other ingredients.
There are also shellac, copal and other gums and resins for making shellac and other varnishes. As you may note there is no mention of milk.
