Greetings, season's best to you,
When painting with rabbits skin glue (1 part to 10 parts water, heated to 140-180 F initially .. just warmed thereafter)...
What amount of aluminum sulfate could be added w/o altering the look of the paint film/pigments ( mostly minerals ) ?
As a final wash to ensure less susceptibility to water damage... what formula of alum to water could be used (parts alum to parts water )
How should it be applied ?
How long should I let my rabbit skin glue painting cure before applying it ?
What about integrating the alum with the glue/water medium ?
I paint about 10 layers at times and I'm hoping to optimize drying time and avoid cracking.
I found the idea of using zinc as a white interesting... would it not crack if used with this medium ? I understand that in oil mediums, for instance, there is a danger of it becoming brittle and cracking.
What is your opinion of egg shell white ? Could it be used with oil or with this rabbit skin glue based distemper medium ? I have not tried it and have only just heard about it being a bright white.
What type of alcohol could be used to wet pigments to be used with a glue/distemper method ?
Would ox gall weaken the film or alter the appearance of the work ?
Are there additives that might help prevent cracking ?
What is the role of clove oil in glue distemper technique ? How much should be added ? Does it alter the look of the paint film ?
PS : I noticed you have some interesting black pigments. Could you please recommend one that would be the best choice for glue distemper painting ?
