![]() ![]() The solution to this one is pretty simple. If the base is thicker than the walls, it will show up as a circular edge around the bottom.Thin areas drying faster than the thick, so the stresses won’t be distributed evenly.Having a bottom too thin, so the stress is too much.Some common variations of thickness include the following: Thickness variations can cause issues with the stress on the pottery, and if you don’t make sure that it is thick, and even, you’re going to have issues. These are the common stresses that happen on the pottery when you fire, and usually, these are the common reasons why pottery cracks.Īnother reason why pottery may stress and crack is because of how thick it is. Stress from cooling it too fast will cause the pottery to crack, possibly shatter as well.Stress from over-firing a pot or firing it multiple times.If you dry it too fast, it causes more stress.Stress from the types of corners that are made, such as sharp corners being made to prevent cracking.Stress from being fired at too high of a temperature.There are different types of stress that can happen with your pots and they are as follows: For example, if you put an unfired pot on the rim side downwards, a crack will show up later on. The way you make clay also affects stress. There is always some level of stress when it shrinks and gets fired, but the problem is, sometimes it’s too much and the clay cracks. Cracks are usually caused by stress in the clay. ![]()
