I'd add to Bob's comment, Sandy King's contributions here and on DPUG are greatly missed.
Denise, you've been making a very great effort to encourage others to begin emulsion making and leading by example. I know from over a decades experience myself that it's a practical proposition.
Maybe the way to encourage people is to get them into alternative printing processes first, Kallitype, Salt prints. Albumen prints etc, then into more simple emulsion making. Just a thought.
