Hi (okay last mail today :)
as I said, I have been focusing on trying to make relief and has coated
my gelatin pretty thick - which leads to long drying times and makes
soaking - sensitisation difficult as the dichromate doesnt penetrate
properly through the gel layer. Are therefore "pre-mixing" the dichromate.
One test indicated that a sample dried "colder" (fan dried in open room
overnight at around 18 deg C) was okay while a sample dried in a
termostate controlled closet (with silica) at 27 deg C, also overnight,
did become totally hardened, both samples was with a low viscosity gel.
Does anyone know or have any experience with, if the temperature
difference here could be the cause?
Or did I accidentally mess up something else...
thanks
Halvor
