Adding Texture to Your Clay: Materials You Can Mix into Your Clay Body

Adding Texture to Your Clay

You can add different materials to your clay body to change its texture.

One very common option is adding clay in the form of grog, which increases both the strength and the texture of the mix. But besides grog, you can also add other materials:

Feldspar
When you use feldspar in earthenware, it creates soft little bumps on the surface.

Tip: Feldspar starts to melt at higher firing temperatures, creating interesting effects on the surface.

Sands
These mixtures can be used, for example, in sculpture, and the effect will vary depending on the type and the amount of sand. As always, it’s a matter of patience and trial and error until you find your own personal mix.

Dry porcelain
If you take dry porcelain and break it into small pieces, you can add it to your clay to create a harder body. After the firing, curious little protrusions will appear. Same thing here: trial and error until you get something personal that you’re happy with.

Molochite
You can add fine or coarse molochite. The coarser version is usually used in large sculptures. The fine one behaves a bit like grog, as we mentioned at the start of the post, but it keeps a whiter tone.

Tip: If you’re using a white clay body, it’s better to use molochite instead of grog, because that way you keep the white colour.

Refractory materials
Even if they don’t melt at typical stoneware/high-fire temperatures, you can still mix them into the clay to get interesting effects. Some potters sand the surface afterwards, creating a rocky, stony texture. Experiment and play with the results.

As you can see, it’s all about testing and testing again… It takes time, and you have to approach it patiently, doing tests only when you can. The good thing is being aware that the world of ceramics is infinite, and even after many years you’ll still be experimenting. Every time you achieve something truly personal, it’s unique and one of a kind – it carries your signature.
