Peter James replies: One method that I have used with good success is to dry small to medium sized items in a microwave oven. It is done in short bursts in the microwave and then the item is removed and the steam evaporates until it cools down. Then I give it another short burst and keep repeating this process. You can go from just cut down to under 6% in less than 30 minutes. This works best on bowls and hollow objects. If you are going to twice turn the item, be sure to leave it thick enough to accommodate the change in shape caused by the shrinking.
