PETER BEARD GROGGED BODY (PF 510)

Peter Beards own clay body recipe is made from a blend of the most plastic white ball clays available today. This white firing, medium textured body is most suitable for hand built pieces to create textural surfaces. A combination of molochite and silica sand gives this body low shrinkage, good warp resistance and green strength.

Firing 1140°C - 1280°C

ASHRAF HANNA RAKU BODY (PF 520)

The very best white smoke fired/raku body on the market. With over 55% molochite, this body can withstand the most extreme thermal shock. This is due to its high alumina plastic ball clay, and three different grades of molochite.

This body has very low shrinkage and has a medium texture and is highly resistant to warping and cracking.

Firing 900°C - 1200°C

JIM ROBISON CRANK BODY (PF 540)

Heavily grogged coarse crank clay. This body has all the elements to allow the maker to produce large textured sculptural pieces. Made from highly plastic iron bearing ball clays. It offers low shrinkage and is ideal for ceramic murals and figurative work.

Firing 1220°C – 1310°C

SVEND BAYER WOOD-FIRING (PF 550)

This clay has been extensively designed with Svend Bayer for wood-firing and in particular prolonged wood-firing. Low iron clays are used to give a vast colour range. Raw Soda Felspar Sand is added to give the clay a slightly grogged feel. Cone 12 can be reached over a long prolonged firing and is suitable for thrown and handbuilt pots.

Firing 1240°C - 1300°C

WHITE STONEWARE (PF 560)

Strong fine-grained plastic clay formulated from the purest white ball clays. A superior body with very smooth throwing characteristics. This body has been designed for the professional production potter. Is excellent for domestic ware with good thermal shock properties. It stands up extremely well and fires to an off white colour.

It works well in oxidising and reduction atmospheres.

Firing 1200°C - 1300°C

WHITE STONEWARE GROGGED (PF 570)

The same body as PF 560, but with 10% 80’s molochite added for potters who require clay with more tooth to aid in the production of larger work with ease of drying. The molochite allows this body to be used for small hand built and coiled pots.

Firing 1200°C - 1300°C

SUPERWHITE EARTHENWARE (PF 580)

At last! Superwhite Earthenware, a white earthenware that throws as well as the best stoneware clays.

PF 580 also offers excellent glaze fit between 1150°C - 1220°C

PROFESSIONAL REDOX (PF 590)

This body can be fired to cone 10 in reduction or oxidisation, and is a beautiful tan coloured smooth to medium textured body. Blended from three of the most plastic ball clays it gives this body the flexibility to be used for small to medium hand built and coiled pots, but can also be used for large domestic ware.

Firing 1220°C - 1300°C

ARCHITECTURAL HANDBUILDING (PF 610)

A cheaper alternative to T material this excellent hand building body contains a higher percentage of fine to medium molochite. The molochite gives it superb sculptural qualities with very low shrinkage, approximately 6% at 1280°C. PF 610 is for potters who need a clay that does not warp under extreme conditions.

It can be used with confidence to create even the largest pieces.

Firing 1180°C - 1300°C

GT MATERIAL (PF 640)

GT Material is a high performance, extremely workable, durable clay body. Carefully selected grades of molochite have been added to give tooth and strength, minimal shrinkage and excellent thermal shock properties GT Material can withstand

demanding sculptural or tile needs and is ideal for large-size pieces.

It is very useful for mixing with other clays to give them strength and can also be used successfully in Raku firings.

Firing 950°C - 1300°C

PF 660 - Black Chunky Crank

Black Chunky Sculpture Clay has a beautiful texture and is excellent for big sculptures and murals. It is a strong body with very low shrinkage, good for building rugged sculptural forms. Its robust nature also makes it ideal for architectural ceramics. Black Chunky Sculpture clay is the caly for everything from large slabs to sculptural works. Firing 1180°C - 1260°C.

PF 670 - Smooth Textured Black

Smooth Textured Black is good for sculptures, hand building or large thrown pieces. This clay has been specially formulated to fire between 1080ºC - 1260ºC with very low shrinkage. Its attractive colour and texture give PF 670 a very distinctive character.

PF 680 - Smooth Textured Black

Smooth Black contains a fine grog which gives a close texture to the body and a fine surface to finished pieces. This smooth finish should appeal to hand builders or sculptors who produce tiles and relief panels or ceramic murals. PF 680 has been formulated to fire between 1080ºC - 1260ºC

PF 700 - Porcelain White Stoneware

For some time now we have been asked by our customers to develop a superior, white, porcelain-like clay which is more reliable and easier to work with than a porcelain body. Porcelain bodies are harder to work with due to their lack of plasticity and are more likely to crack, warp or shrink than stoneware bodies. PF 700 is not as translucent as porcelain, unless in very thin cross-sections at high temperatures. It is, however just as white, has all the qualities of a good stoneware body and produces porcelain-like results at a lower cost. PF 700 has been formulated from the purest, highest quality white clays to give a porcelain-like appearance but without the difficulties that working with porcelain can create. PF 700 is suitable for throwing, jigger and jollying, press moulding and modelling.

Firing 1220°-1300°C

Margaret Frith Porcelain (Smooth)

We have great pleasure in introducing Margaret Frith Porcelain. This Porcelain has been developed as an alternative to our ‘Sliphoused’ range. Using the whitest powdered ingredients and homogenised using our specialised mixing equipment, this method long being the preferred way by many potters of offering more plasticity and throwability.

Firing: 1220°C-1280°C (White & transclucent)
