Abstract
Shelf liners and methods of using the same to protect kiln interiors from glaze running or dripping from ceramic objects being fired are disclosed. The disclosed shelf liners include a first layer made from an alumina-rich material and a second layer made from a silica-rich material. Optionally a third layer also made from an alumina-rich material is configured such that the second layer is disposed between the first and third layers. The liners are installed in kilns such that molten glaze running off of a ceramic body drips onto the first layer of the liner and is prevented from contacting the kiln shelf.
Claims20
A liner for a kiln shelf, comprising:
- a first layer made from an alumina-rich material;
- and
- a second layer made from a silica-rich material;
- wherein the second layer is thicker than the first layer.
A liner for a kiln shelf, comprising:
- a first layer made from a calcium carbonate-rich material;
- and
- a second layer made from a silica-rich material;
- wherein the second layer is at least as thick as the first layer.
A lining material for use in kilns, comprising:
- a first layer made from an alumina-rich material comprising calcined alumina;
- and
- a second layer made from a silica-rich material comprising quartz;
- wherein the second layer is at least as thick as the first layer.
