We have created a similar rich lustrous look on our wooden bowls by using a process called “Ebonizing.” The ebonizing solution is made from two common products, vinegar and steel wool. The steel wool is soaked overnight in a plastic container filled with vinegar, creating an “iron solution.” When this solution is applied to the bowl, it reacts immediately turning the Red Oak into a rich Royal Blue color. Ebonizing is a safe, easy way to create beautiful bowls with originality and character. This spectacular solid Ebonized Red Oak wood bowl is turned by the craftsmen at the Holland Bowl Mill, one of the last commercial wood bowl mills in production in the United States. This is a side salad serving bowl and can serve a salad for 1 person. Unique present for the holidays, weddings, housewarmings and birthdays! Wood grain will vary. Hand wash only. – Material Solid Red Oak wood – All Natural Finish – Origin Holland, MI
