Stilts are small refractory or metallic devices used inside the kiln to support the glazed pieces in positions that prevent their direct contact with shelves or other pieces, especially when glazes are applied at the base or in critical areas. Their design, often with three points of support, responds to the need to offer stability with the minimum surface in contact, thus reducing the presence of marks or defects after firing.
These supports provide some distance between the workpiece and the support surfaces, allowing the glaze to melt and distribute properly without permanently adhering to the kiln structure. In addition, the use of stilts is especially beneficial in firings where the glaze softens enough to flow downward, as a slight tilt or strategic position can help achieve specific decorative effects. Pieces with curved bases, small feet or irregular designs benefit from these tools, as they ensure a clean, professional finish.
Interesting Fact
Stilts were widely used in the production of glazed earthenware pottery during the Renaissance, when majolica glazed pieces required protection on kiln shelves.
Helpful Tip
Place the stilt in strategic areas of the piece to minimize the impact on the glaze, and make sure that the contact points are as small as possible to avoid visible marks after firing.
