What is a Seconds? During production, and as a result of our high-quality standards, we produce a quantity of Near Perfect pieces every week. During kiln firing, slight variations in temperature can occur which result in glazed pots appearing slightly lighter or darker than the ideal standard, or minor surface imperfections can arise. These are purely cosmetic blemishes and in no way detract from the safety, strength or durability of the pieces concerned. In addition, they are 100% safe to use in the dishwasher, freezer, microwave and oven.
