Eddie, I guess I shouldn't use such strong terms. You are right, it will work. But they add a salt solution to it to keep it from gelling like untreated hide glue. As soon as it gels, it is all good glue. It just has to gel first, which it is designed not to do until it starts to dry.
Kiwijim, what is bakers definition of commercial hide glue, or gelatin. Gelatin is commercial animal glue. If Davies gelatin is made from "beef skin" it is commercial hide glue. How can commercial hide glue be at least as strong as commercial hide glue, much less stronger. They just treat it with a few more chemicals and call it gelatin it so people will eat it. Justin
