The ink has about a 40-minute lifespan in the etching solution (after which time it begins to dissolve), but that is plenty of time to get a crisp, deep etch [PHOTO C]. The solution creates a waxy resist over the entire silver plate. I then hand engrave the areas which are to be etched. This removes the resist so that the engraved
