Buff Stoneware Clay

Create beautiful ceramic art with Buff Stoneware Clay, a smoothly textured grey clay expertly designed for throwing, sculpting, and modelling. Versatile enough for small-scale and life-sized projects alike, it is strong and reliable enough for structural mould-making.

Key Features & Benefits

• Expertly Blended & "Well-Behaved": An outstanding general-purpose body crafted from a quality blend of fireclays, ball clay, and china clay.

• Dual-Purpose Versatility: Highly adaptable for both earthenware and stoneware use. It fires to a pleasant yellow/buff colour at earthenware temperatures, progressing to a darker grey with a fine speckle under reduction or at higher stoneware temperatures.

• Studio & School Favourite: Extremely popular with stoneware potters as a reliable production body under both oxidation and reduction firing, while also remaining a favourite in educational settings due to its high tolerance and ease of use.

Usage & Storage Guide

This is a moist, wet clay that will dry out if left unsealed. It requires high-temperature firing in a kiln to permanently harden.

• Always keep the clay securely sealed in its plastic bag when not in use.

• Keep your active models damp to prevent premature drying during the creative process.
