Yes, dry plates that have been coated with a gelatine/chrome alum mix
previously. I use Tetanal "work"emulsion, but I'm keen to try multicoloured
gum on glass in the future.

No, glass rods maybe! I will try to get some made for me.

I find too viscous an emulsion is difficult to fix. I apply two coats of
runny emulsion.
I always harden in the stopbath, for which I use water and Ilford film
hardener. I've had a lot of trouble with lifting and frilling even with cold
baths.
