This piece is best to Decorative use. In firing, this glaze combination is prone to blistering. In this instance I believe that these blisters add significantly to it's beauty and character so I have decided to leave them. However, this decision will make it harder to clean and so for this reason I would say that this bowl is destined for life as a pampered beauty and not a working piece. And really, who'd want to cover that beautiful interior up with mashed potatoes anyway!?
