Manufacturer: Scarva

A medium grogged alternative to our Standard Crank (ES50), ES60 offers a finer surface and closer texture. This clay is ideal for hand builders and sculptors who require a warm, plastic clay with excellent green strength and a smoother finish than standard cranks offer. ES60 is suitable for oxidation, reduction and raku firings. Under oxidation ES60 gives a toasted buff colour, under reduction a warm speckled orange.
