    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,
