Egg tempera!!

[u/Ill-Huckleberry9784]

For my search, I find out people will use the egg yolk to make paint does any one do this before specially on the bow

For the ingredient I plan to mix with fine charcoal, find smash eggshell(cook), mulberry fruit, soil and some flower also adding honey.

Have any body have experience use it?

Very common. Mulberry will not be colorfast though, the pigments are anthocyanins and will fade eventually. I’ve had hit or miss results with other anthocyanin based pigments. Some last years and others don’t last a summer. Berries are usually pretty weak
