Re: Black Cat Carbon Tissue

Unless I have done the conversion incorrectly the wet height coating
I get with about 1 ml of glop per one square inch of coating surface
is about 1.0 mm, not 0.1 mm. The thickness of the flexible magnetic
sheeting material I roll the rod over to spread the warm glop is
0.043", which by my conversion is 1.09 mm.

I have no problem with blistering at this point, though I have seen
it in the past. It can result from bubbles in the original glop that
did not dissipate, or it can result from raising the temperature too
fast when developing the carbon relief. I also see it from time to
time when increasing the alkalinity of the development water to force
develop the image beyond where it normally wants to go with just
plain water.
