Yellow wood glue
dries by evaporation, shrinking as it dries. Therefore, it is a good choice if you have a clean break to repair, with no gaps. (If there are gaps and the glue shrinks, the two parts may not bond.) Also, it is a slow-drying glue, so clamps will be necessary to hold the item in place during the drying process. Yellow glue will absorb into the wood fibers, forming a strong bond that will not easily be broken.
