Hello,
I want to use glyoxal for sizing my reception paper for carbon transfers. I use a 5% gelatin for sizing, I have read several posts and if I understand :
Outdoor use only
Make a 10% solution of 40% glyoxal commercial glyoxal at 1:9. I.E. : 10ml of 40% glyoxal and 90ml distilled water.
Use for 100ml of 5% gelatin solution 5ml of this 10% glyoxal solution.
Hardening in 4-8 hours but wait 24h minimum to evacuate fumes
or
I read in the book of alternative photographics process third edition :
15ml of 40% Glyoxal in 250ml of 2,6% gelatin
or
15ml of 40% Glyoxal in 1000ml distilled water (immersion option)
There is a big difference in concentration between sources
What is the best option for you ?
And if you have different use share please
Best regards,
