I’ve recently found myself using and/or wanting to use hide glue more frequently than in the past. (A recent unfortunate experience with a glue-up using good ol’ yellow PVA might have something to do with it….) This being the case, I’m trying to sort out the hide glue options.
Broadly speaking, as I understand things, there are two categories: hot hide glue and liquid hide glue. The former is the “original” version of hide glue, and typically requires a glue pot, some mixing, adding urea (and maybe salt), and the proper incantations to the responsible deities. The latter is a group of modern formulations, generally of the pour-and-play variety.
Looking around, one finds various sources for hot hide glue, with recommendations for adding urea and salt and the hairs of a leopard frog. There are also various liquid hide glues out there, the most common perhaps being the Tite Bond Liquid Hide Glue and the oft-recommended Old Brown Glue. [FWIW, the Tite Bond is the only hide glue I’ve used. So far, anyway.]
So…I’m tossing this up hoping that those with lots of hide glue knowledge/experience will chime in with pros and cons of the various options, recommendations, etc., with the objective of getting a little learning about the subject. I’ve done the requisite Google searches, and find that most of what comes up doesn’t answer as many questions as it raises. That said, if there’s a site/article or whatever out there that I should be looking at, please feel free to point me in that direction.
