>Is it ok to mix hot hide glue from two different sources Yes, Someone told me the lighter ones, crystals, are better quality. If you want the best quality use only the best crystals. But after it has been mixed up and cooled and then heated up again, someone told me it has different characteristics from the original and even more if it has been cooled and heated up a 3rd time. It gets harder and more brittle after each heating which is good for some applications, like felt to metal but not so good bonding wood to wood, or so I have been told. The book "Tone Building", American Steel and Wire, the original one with all 3 conferences has excellent narratives how to use glue and how it is used. ---ric ----- Original Message ----- From: Keith Roberts <kpiano@goldrush.com> To: <pianotech@ptg.org> Sent: Saturday, August 31, 2002 12:38 AM Subject: hide glue Is it ok to mix hot hide glue from two different sources? The crystals are different shades, one lighter. Seems like someone told me not to but I can't think of why. Keith R
