thank you for sharing, jan. we all learn something from this knowledgable group.
interesting about the powdered milk. i've used evaporated milk, straight from the can to emulsify an ink stain on clothing before laundering, and diluted 'em' to seal cracks in pottery to make them watertight. it's the casein from the milk when heated in a low temperature oven that flows into the crack and when it dries makes a tight seal.
