O.k. I am hitting this again.
I have abunch of 1.3mm plates coming in. Actual vintage plates that I am going to strip down and reuse. I also have a supply of 5" square 1.3mm glass.
I've also gotten a some formulight hardener from the good people at PF.
Here is my question -
It says I can harden the gelatin with this stuff. Harden the emulsion before applying, harden in development, and of course I am using a hardening fix.
That is a lot of hardening going on.
While the prospect of my emulsion being harder than the arteries of 67 year-old smoker who has been on Atkins for the last 50 years is nice, I want to do this right.
I figure hardening the subbing layer is a no-brainer. Easy to do. And since the emulsion goes over it, not too much of an issue.
Now, I think I will want to harden the emulsion as it is poured on.
This is the tricky part. Apparently I can treat only as much emuslion as I need, as you can't "reuse" emulsion that has the hardener added.
What exactly does this mean? Do I have a time limit during which I MUST use the liquid emulsion that I have added hardener to, or, as long as I keep it hot and liquid, can I use this stuff? Does the hardening only happen when the emulsion sets?
I want to reduce waste as much as possible here.
Also, would it be wise to harden in development or just save it for fix?
