It seems like we had a setback in our quest in making great glass negatives. The positive thing is that we think we have a better idea about what’s going wrong. First off we mixed up some info in our first batch of plates, where our initial gelatine sub-layer actually worked. The latest plates had a varnish sub-layer, and they seemed to work well as well. The problem appears to be that we used photoflo in the emulsion. The use of windex after the caustic soda bath might have contributed to the emulsion slipping as well.
