PRAF , better known in the ceramic community as "Rafael" , is a premium white stoneware clay, specially designed for artistic ceramics. Its composition offers the perfect balance between stability and texture, making it the first choice for sculpture , murals and the Raku technique.

Its characteristic ivory color after firing acts as the ideal canvas for glazes and oxides, allowing the colors to develop intense and bright tones.

At Neraw Materials, Rafael (PRAF) is the clay we highly recommend for anyone who wants to experiment with Raku or build large sculptures. The security you feel while drying is unsurpassed.

Pro Tip: If using it for utilitarian stoneware objects, fire at 1250°C to achieve maximum density and the purest ivory color.
