Working Notes

This clay has a slightly coarse texture when throwing, but it shapes well and tolerates changes. With hand building it cuts to a clean edge and has a firm plastic feel.

The colour at bisque is more yellow than buff, this darkens with a heavy mottling at a higher temperature. This works well with a light application of a glaze allowing the character of the clay to show through.

The spots/speckles within this clay can stick to the shelves when fired at higher temperatures. Flat bottomed wares should be stilted to protect shelves.

Health & Safety

As the clay contains crystalline silica avoid inhaling the dust from dried out clay. Wear a P3 mask, wash hands after use and clean up using a damp sponge. Dust off dirty clothes and aprons outside.

My favourite clay

I’ve been using this clay for a while to hand build plates and love the finished results when glazed. Embossing detail seems easier than carving.
Yes, the spots come off onto my bat washed kiln shelves, but I’m living with it for now (it’s the only clay I’m currently using) as I found cookies can make some larger pieces warp.

Sibelco chocolate chocolate speckled ckay

Speedy delivery, love this clay although I do get a good bit of exfoliation on the wheel 🤣 it's great to leave some showing when glazing too.

Good for throwing and looks great

This clay is great to throw with and the speckles look really good through a more transparent coloured glaze or a clear glossy glaze. This is fired to cone 6 with Persian Red and with a Celadon green.

Beautiful clay!

I love this clay for making plant pots. I love all of the speckles. Some do go on the kiln shelf but doesn't cause much issues.
