On the outside natural oak with a breathtaking color structure, inside black ebonized surface.
The bowl was hand made on a lathe. The wood is surface treated with the finest sandpaper and polished to a silky finish. It is protected by a coating that is suitable for contact with food. You can wash the bowl with a soft cloth and soapy water. If it loses the shine, you can restore it by relubricating it with oil, preferably linseed or paraffin oil.
