Sibelco Chocolate Speckle Clay *Warehouse Deal*

*A small number of Chocolate Speckle clay bags have started to grow mould on some surfaces of the clay which can easily be cut or scraped off. This is a natural occurrence in damp environments.

Texture: Smooth textured

Unfired characteristics: A finely grogged stoneware, relatively smooth in texture. The wet clay is a yellow buff with a few black flecks

Fired colour: Brown mottling on a yellow buff

Shrinkage: 1200°C - 6% (For further information, refer to the Technical Data Sheet in the product attachments)

Grog: 20%, 0.5mm grain size

Ideal for hand building and throwing.

Ideal bisque: 999°C (cone 06)

Glaze range: 1000°C to 1250°C (cone 06 - cone 8)

Spots appear from 1150°C

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.
