Our Hollow Kiln Shelves are engineered to deliver superior performance, durability, and efficiency for ceramic, pottery, porcelain, and tile firing applications. Featuring an innovative hollow-core construction, these shelves are significantly lighter than traditional solid shelves while maintaining exceptional strength and stability.

Why Choose Hollow Kiln Shelves?

Lighter Weight
The hollow-core design reduces overall shelf weight, making kiln loading and unloading easier while helping to minimise back strain and operator fatigue. Their lighter weight also contributes to lower shipping costs and improved kiln efficiency, reducing energy consumption during firing.

Flatter Surface
Each shelf is precision ground on both the top and bottom surfaces to ensure exceptional flatness. This helps maintain the shape of fired ware, particularly tiles and large flat pieces, while providing consistent support throughout the firing cycle.

Stronger and More Durable
Designed for long service life, Hollow Kiln Shelves offer excellent resistance to warping and thermal stress. Their reinforced structure helps prevent crack propagation through the core, resulting in greater durability, fewer replacements, and more firing cycles over the life of the shelf.
