Moved un-answered questions here for further discussion.

Q. In this thread there was some discussion about using Sodium Dichromate instead of Potassium Dichromate and increasing the amounts of that and Glycerine to increase photosensitivity. Has anyone had good results with this?

Q. What have people done about condensation on the cold plate? Keep it in a container with dessicant while it's not being used?

Q. Any chemists out there have any suggestions for a "preservative" to limit the glycerin dark reaction?

Why do we want to limit it? It is the dark reaction additive that gives the G307 its increased sensitivity.

Because it limits the storage time of prepared plates. If we could stop this reaction until it's desired, more plates could be made ahead of time, which would result in having more available of a known quality.
