Great wood bowl turned from a very common tree use in landscaping. You probably have one in your yard. I find it a very beautiful wood. The bowl is turned from a half log, which gives it the saddle appearance at the top of the bowl.
Natural edged bowls are turned "green" then dried over time. Once they are dry they are return, as the usually distort in drying, then finished. Depending on the size of the bowl it can take 2-14 months to produce this bowl.
So be sure and check my web site under wood bowls and wood platters for more pictures and examples.
