Attractively flecked stoneware body based on a ball clays and fireclay deposits mined from our site in South Staffordshire, near Walsall.
Superb throwing properties for small or large pieces.
Flecking burns nicely through covering glazes giving a reduction fired appearance under oxidising conditions.
An extremely good body for thrown domestic stoneware.
Kiln shelves must be well coated with refractory wash to prevent sticking during firing
Standard full bag size 12.5Kg

Information about our basalt flecking agent:

Please note that basalt is a naturally-occurring mineral. The user must sample/batch test in their own application before proceeding as we cannot accept any liability for fleck variation which is outside of our control.

Fleck size and density is variable from batch-to-batch due to the characteristics of the raw material supplied to us.

Melt properties: Can be variable, sometimes causing raised flecks on the surface of the fired ware. Our tests show that a sufficient glaze layer will 'flux' these flecks causing them to flatten out. Unglazed areas can be wet-sanded after firing. This characteristic is not evident in our reduction-fired tests.

Microwave Use: Basalt is an iron-bearing compound which is not metallic, therefore fired ware can be used in a microwave.

Please note our clay is sold by approximate weight. Your total order weight for a specific clay body will be despatched in the most economic combination of packs possible. If you require individual packs of a specific size, please state this in the Special Instructions during checkout.

To comply with RHA regulations concerning tail-lift deliveries (where there is no fork-lift truck available at the delivery point) the maximum net weight of clay we are now permitted to pack on standard pallet is 950kg (76 x 12.5kg bags of clay). To achieve the best price for your clay, please add the full 1000kg to your cart when checking out and we will make the necessary weight adjustment/refund when we receive the order.

We have added cone numbers to our firing ranges for guidance purposes. Please refer to the 60c/hr column for large regular or self-supporting cones on the Orton Cones Conversion Chart which can be downloaded here.

* You can find typical shrinkage data in the CLAY ANALYSES chart which is available for download from this link: https://www.potclays.co.uk/Technical-Information. These figures are taken from tests performed under laboratory conditions and are intended for guidance only. For this reason, it is always recommended to also run shrinkage tests in your own application.
