It bonds much better than you might think. Very strong bond.
Smear it on while it is still warm and lumpy. This stuff makes a very strong glue.
Gelatine works because it is made of protein by partially dissolving animal connective tissue, collagen, in water. You find it as a powder in the market. I recall my Dad making this mix for wood furniture where legs had become loose etc.
Look for the book ” Sneaky Uses For Everyday Things” , by Cy Tymony
