Here is a birch burl bowl I turned this winter. It is the 2nd largest of 5, I cored out of the burl. It measeres around 15" in dia. by 7"+ high. It is turned thin for a bowl of it's size. It warped so bad drying that I had no choice but to make it thin to make it round again. It is very light in weight, less than the next one in the set of cored blanks. The largest bowl ot of the set warped so bad I had to take half it's height away to return it round.
