The first time I ever sat down at a Pottery Wheel, I thought all clay was the same. How little did I know? I thought you throw some clay on the wheel and some water, and that was it.
From the Texture of your Clay to the Types of Glazes, all the way down to the Firing Process, choosing clay can be difficult.
Flash Forward after Hundreds of Pounds of Wedged and Thrown Clay I have learned a thing or two about Choosing Clay.
Below I tell you what to look out for when Picking Out Your Clay. I also give you a Short Overview of My Favorites and the ones you might want to choose.
What To Look For When Choosing Your Clay
What Cone size do you need
Cone size refers to the temperature you will be firing your clay.
This is the most essential part of choosing your clay. If you fire cone 05 clay to cone 5, the clay will melt. If you fire to cone 5 clay to cone 05, the clay will not vitrify (partials fuse together to make the clay nonporous), and your piece will not be dinnerware safe.
How much Grog or Sand does the Clay have
Sand is on the finer side. Grog is clay that has been fired then ground up. The Grog can be ground up super fine or course. Grog and Sand help to keep the clay firm when hand-building and throwing large pieces on the wheel. It also reduces the shrinkage in clay during firing and helps gases to escape. The type and amount will determine how coarse you want your clay to be.
How much Plasticity does it have
Plasticity refers to the flexibility and smoothness in the clay. You want to be able to push, pull, and mold the clay to your desired shape.
How well does it throw on the Wheel
The ability to throw the clay into your desired shape without struggling, hurting your hands or having the clay collapse.
Is the Clay good for Hand building
The ability to pull-push and move the clay around without breaking and cracking and having the clay stay firm enough to keep its shape.

Recommended Clay Helpers
When playing with clay we all want helpers to make it easier for us. These are a few things that may help you too, especially if you recycle your Clay.
Must-Have Clay Cutter
This Mudwire is by far my favorite. The length of the wire and feel of the handles are perfect for me. Even with Clay covered hands.
When cutting through your Clay, you want to have control over how much clay you are cutting off. The 13 – inch wire gives you that control. When cutting pieces off the wheel, you don’t want to have to wrap the extra wire around your fingers. This Cutter allows you to cut your pottery off using both handles which makes it easier and gives you a more even cut.
