Don,
I really like those nifty red molds!
I only use microwave heated water in a large Pyrex bowl. No flame or electric burner is needed. This is how I melt my hide glue, too. Into that Pyrex bowl (demonstrated by spokes
model, Mollie) goes the glass jelly jar with the broken pieces of old dried up rosin and the new chunks of Pop's, which acts as the solvent. I suppose that one could use tiny amounts of turpentine or other volatile agents found in pine pitch. Folks who happen to live near a large and leaky Moneterey pine could scrape of some and use that instead. New Pop's is pretty consistent and has had all of the bugs strained out of it.
In these last couple of reconstituted batches, I like to use about 20-25% Pop's to the balance in scraps. The large bowl of water acts as a steady source of heat energy, so no explosions. I like to get it up to boiling water temperature and keep it there for few minutes, with lots of stirring. I use long deck screws, one of which has a small wooden handle now. It ends up being about as thick as good pancake syrup. I made my own paper cups out of card stock and it worked pretty well. The Petz and Pop's containers fit these card stock cylinders well. I sealed up the bottom hole of the Petz containers with clear shipping tape to keep it somewhat air tight. Don Prell says that he uses little cardboard boxes that he makes, so I poured a little of the mixture into an empty cardboard cylinder Kolstein container. Don says that he just uses a sharp knife to peel away as much cardboard as he needs.
This has been a fun little project and now every student bow in the shop is rosined and ready to go for Christmas. The one must is a hard clean surface to work on, covered in layers of newspaper. This process is very messy, so don't have any kind of fabric near by. Hope that you have as much fun as I did. It is like cooking class without the calories.
