Michael has always prided himself with taking techniques from the “art” ceramics world from which he comes, and applying them into larger production. Panthera is a reactive glaze that has taken Michael two years to develop. Glaze variances may be different from piece to piece, and in fact is part of the beauty of the glaze. Each piece is hand-finished with 24k gold or platinum, made in the USA, and is food and dishwasher safe. These wares are not for use in a microwave.
