NZ China Clay Ultrafine is a highly refined kaolin clay sourced from New Zealand, known for its exceptional purity and fine particle size. In ceramics, this clay is valued for its ability to improve the plasticity of clay bodies, enhance the whiteness and brightness of glazes, and contribute to the smoothness of finished products.
 
Applications in Ceramics:
Porcelain Production: NZ China Clay Ultrafine is commonly used in porcelain and bone china formulations, where its high purity and fineness contribute to the translucency, whiteness, and smooth texture that porcelain is known for.
Glaze Additive: As an ultrafine clay, it acts as an effective suspension agent in glazes, helping to maintain an even consistency and preventing settling.
 
Improving Workability: When added to stoneware and other clay bodies, it enhances plasticity, making the clay easier to shape and work with.​​​​​​​
 
Safety Considerations: NZ China Clay is generally safe for use in ceramics, including on food-contact surfaces, due to its natural composition. However, like all fine powders, inhalation of dust should be avoided. Proper PPE, such as masks, and adequate ventilation are recommended during handling.
