I have an old side table that was getting progressively more wobbly and while trying to determine the most needy joint to rebond, I took the entire thing apart. The glue is shiney and brittle, seems to scrape/chip off easily with a putty knife. I used a heat gun to see if it would soften or liquify but it bubbles then turns powdery rather quickly. My ???? is is this hyde glue and what would be the best glue to rebond the joints. I think this table is French made and pre WWII.
Also, as I was heating up the glue, the finished surfaces getting the heat would change from a flat patina to a shiny surface. Is this characteristic of shellac?? What Up!! Thanks for your help. JCB
