In the passage concerning fish glue it is mentioned that: To prevent the glue from gelatinizing at room temperature an acid such as hydrocloric or asetic acid is added and the adhesiveness of the material is little affected. I wonder if one added a small amount of the above mentioned acids to hide glue the open time of the glue could be extended? Markus.

In some woodworking forums they talked about adding urine to slow the gelling of hide glue

Jiao. If you add garlic to the glue will you not have a strange smelling bow? Urea can also be used and I have done tests and with moderate amounts added I could not see any weakening og the glue line.
It was the article in itself that I found interesting, I just added the acid thing as a sideline.
