Some time ago I saw a message here about soaking cracked bowls in a mixture of glue & water. Of the 60+ bowls I roughed out in Jan & Feb,
5 developed cracks of varying degrees. As an experiment I mixed 1/3 white glue to 2/3 water and soaked them for 3 to 4 days. Three large sweetgum bowls showed no improvement, but I had no covered container large enough to completely submerge them so used plastic bags and it is iffy that they were wet all over the whole time.Two sassafras bowls about 10 inches were soaked in a covered plastic container with a piece of brick to hold them under the surface. One showed no improvement and the last one was completely healed. I cannot even find where the crack was, and it extended from the rim down to the dovetail on the base. The cracks on both were open about 1/8 inch at the rim.
So with a good test on two bowls I got 50% healing of the cracks. Anyone else trying this method?
