Denise, I said "MIGHT", not will. You yourself have said here that the grain at ISO 100 is about like TriX. That is nearly 2 stops loss in speed / grain. Not very good but usable. You make my point. It depends on what you expect from your film. A lot has to be done on this. What you present is a very fine 4x5 emulsion in fact, but a just usable 120 emulsion, at least to some.

And, as for the workshop, I said nothing about dry plate. Please see the details here:
