How durable is the fired clay?
Since polymer clay is a plastic, it’s very durable. The colors of polymer clay generally are stable in normal use, although a piece exposed to direct sunlight for years (such as a suncatcher or wind chime) will probably fade. There are artists who have pieces decades old that still look like new. Thin pieces sometimes do break or chip. If your clay piece will be handled a lot or be in danger of bumps, and it will include protrusions or thin pieces, choose one of the stronger clay brands, and fire it for a longer time than usual for added strength.
