I thought I would start this thread for others and my education. I never heard of hide glue until reading a book Woodwork Right Technique
by Bob Moran. Like many, I have exclusively used white and yellow carpenter glue, and a few times epoxy for my projects.
Hide glue has been around for over 3000 years and still holding Egyptian mummy boxes together. It is made from animal hides and is essentially an industrial gelatin. Itís the same thing we eat just stronger. One interesting property is that is can be unglued easily, making it perfect to repair furniture and musical instruments that are put together with this glue. That very reason makes this glue unsuitable for outdoor furniture.
I am new to hide glue. I have not experimented beyond melting it and gluing several scrap wood pieces together together. I understand how to thin it and thicken it. I can feel the ďgrabĒ when it starts to set. It seems that this is one of the shortest open time glue around but the one of the best for fine wood projects.
The research I have done has turned up has left many unanswered questions. It appears there is a wide range of temperatures the pot can be kept at 140-165. On the other hand some information indicates that it can be burnt above 155. Is the temperature manufacture specific?
Some say throw it away at the end of the day; while others keep adding to the pot each day. I have also read that unused portions can be frozen to prevent bacteria from forming. The information did not specify how long it could be frozen nor any hint of the strength after freezing. Can anyone out there please give comments on freezing?
It also seems that the ratio of dry hide glue to water recommendations vary considerably from 1:1 to 1:2 again no data on strength. To me the more water means a longer the open time but also weaker glue. There again it seems to be a personal preference and perhaps the application. Comments?
Several recommend distilled water. I can see that it would have been easy for the Egyptians to distill water to make purer glue. So for my use, Im thinking the distilled water makes sense.
I also read that one can increase the open time by adding urea or salt. But I would think that would damage the glue. Im guessing it is best to avoid this, maybe some experienced hide gluers can give insight to this.
