By varying the amounts of various ingredients, such as Dragon’s Blood, various lacquer colours can be achieved. Below is a picture showing three different batches of lacquer I have made applied to microscope parts.
I am about to make up a fresh batch of yellow as I have a piece to lacquer for a customer, I have some leftover yellow lacquer but I don’t want to risk using it. The lacquer ingredients are dissolved in pure ethanol, over time the ethanol takes up water and water is death to lacquer. Any water in your lacquer and you will get cloudiness and a nasty finish. It’s less trouble to make up fresh.
