gandolfi, one more question - what inks do you use? are they litho-inks+lenseed oil or some from tube or maybe somewhat else?
i have tried some cheap oil-based inks and they works too bad.
I use lithographic oils - and never lenseed oil - I most often need to make the oil stiffer, not softer, so I use Magnesium Carbonate to stiffen the oil...
My first feeble attempts at carbon transfer. 4x5 negs .not without issues, but I have hope.

OK, this is my second tintype using the Rockland Collodion Parlour Kit. There are a bunch of artifacts in the emulsion that I would love to know 1) what to call them and 2) how do they occur.
a) Little black dots sprinkled throughout. They look like the emulsion disappeared from those spots. When originally coated and even after the fixing those spots were not there. They appeared as the plate dried.
b) Little wavy lines on the edge of the plate which when you examine the plate looks like the emulsion wrinkled.
All help greatly appreciated.
