I’d seen this mentioned a few times here I believe and elsewhere on the web about a method of drying green wood faster without checking or splitting. I found the log of white oak along the side of the road that had been cut up recently from a downed tree and was able to get 3 small bowl blanks from it. The first one I turned (about a week ago) I went all the way to a thin wall leaving pretty much just sanding and finishing the bottom off. One is very rough bowl shape with no hollowing (may make it with a lid) and the third is another rough turned hollow form. They’re all about the same sizes (~ 11 cm diameter) but the other second and third I left with very thick walls.

What I tried with the little finger bowl was soaking it about 24 hrs. in denatured alcohol while the other two I just put into an area of the shop. Once the soaking was complete I put the bowl in double brown paper bags and left it in the house.

Yesterday evening I decided to take a peak at all 3 to see how they were doing. The finger bowl has become more oval now (no surprise) but what was surprising is that there were no checks or cracks of any kind in it. Unfortunately the same cannot be said for the other 2 rough turned. The finger bowl was done about 2 days prior to these and there’s already some splitting here.

I can’t say with any certainty nor do I know how it will eventually turn out but it appears the alki treatment does keep thin-walled green vessels from checking. I’ll comment on it again in a month or so what I look at the finger bowl.
