I completed another bowl today using a different technique. Normally when a bowl is turned, the wood will have been fully dried before turning.
This bowl was turned while the wood was still wet with sap moisture. What this means is that the bowl, as the wood dries, will change shape due to the wood shrinkage. This change in shape is most visible in the sideview photos. The wavy profile of the rim, is entirely a function and result of the natural drying process.
This process makes for a very unique shape. One that can not be duplicated as the process is controlled by nature.
I hope you enjoy the photos.
