Alcohol paint is very famous among violin makers, and its formula comes from Simone Sacconi, whose book "The Secret of Stradivari" is almost a Bible for violin makers.

All ingredients in the formula can be purchased on Taobao. The formula in this video is,

180 grams of native insect glue

Shandalak 30g

30g olive resin

Lavender essential oil 15ml

Industrial alcohol is approximately 500ml

I made a slight modification to this recipe, and the production process is the same,

Purple grass mushroom (i.e. native cordyceps) 120g

Indian transparent insect glue 120g

Shandalak (Sandalwood) 40g

40 grams of olive resin

Lavender essential oil 20ml

99.7% industrial alcohol 750ml

Adding transparent cordyceps not only makes it harder, but also provides better protection for the resulting paint film. In addition, it is basically colorless and can dilute the purple tone of native cordyceps a little,

It is easier to color varnish.
