My understanding is that it has all the strength properties of hot hide glue, although I realize there is some controversy over that. Thanks for the panel pictures. > I have never used cold hide glue. From what I understand you can make your own by adding over 30% urea to hot glue - not sure how much. The urea definitely weakens the glue - I've been told - but I am not sure it is enough to worry about. Sounds like an opportunity to experiment. Make your own cold glue and compare it with the hot glue. Get back to us with your findings.
