Hardening With Glyoxal: One Shot?
I'm mixing small batches (100 ml) of 3 per cent Knox with 2.5 mls of Glyoxal (oh, and a splash of rye whiskey for bubbles) for sizing paper with a sponge brush. Can I reuse this mixture by simply reheating in the microwave after it cools and gels overnight? Is there a shelf life? Thx. ~m RNP Arrays: An Open Source Digital Negative Project www.inkjetnegative.com
