Abstract

The present invention relates to kiln furniture kits for supporting ceramic products, such as for example sanitary ware, during high temperature processes in a kiln. The invention further relates to rolling element holders as part of the kiln furniture kits according to the present invention for deformation and breakage free firing or drying of ceramic products.

First claim

The invention claimed is:

1. A kiln furniture kit for use in drying and/or firing ceramics products, comprising
one or more rolling element holders,
one or more rolling elements,
one or more spacers configured to burn without residue in a firing and/or drying process,
a base batt, and
one or more support segments,
wherein the one or more rolling element holders comprise perforations configured to hold the one or more rolling elements.

2. The kiln furniture kit according to claim 1 , further comprising: a base, wherein the rolling element holder and the base form an integral part.

3. The kiln furniture kit according to claim 1 , wherein:
the rolling element holder is configured to support ceramic products to be fired,
the rolling element holder comprises one or more wells formed on a lower surface of the rolling element holder, and
the one or more wells on the lower surface of the rolling element holder are configured to be placed over one or more rolling elements sitting on the base batt.

4. The kiln furniture kit according to claim 1 , wherein the one or more rolling elements are selected from balls or rollers.

5. The kiln furniture kit according to claim 1 , wherein the rolling elements comprise a material selected from the group consisting of alumina, silico aluminates, carbides, nitrides, zirconia, and mixtures thereof.

6. A kiln furniture kit according to claim 5 , wherein the base batt comprises a material selected from the group consisting of standard silicate, alumina, silico-aluminate, carbide, and mixtures thereof.

7. The kiln furniture kit according to claim 6 , wherein the one or more support segments are coated by a material comprising alumina, silico-aluminate, silica, magnesia, or mixtures thereof.

8. The kiln furniture kit according to claim 7 , wherein the rolling element holder is configured to support ceramic products to be fired,
the rolling element holder comprises one or more wells formed on a lower surface of the rolling element holder, and
the one or more wells on the lower surface of the rolling element holder are configured to be placed over one or more rolling elements sitting on the base batt.

9. The kiln furniture kit according to claim 8 , wherein the one or more rolling elements are selected from balls or rollers.

10. The kiln furniture kit according to claim 9 , wherein the one or more spacers is configured:
to maintain the other elements of the kiln furniture in place prior to a firing and/or drying process, and
to disintegrate or shrink during firing and/or drying process to allow the other elements of the kit to freely move.

11. The kiln furniture kit according to claim 1 , wherein the one or more spacers is configured:
to maintain the other elements of the kiln furniture in place prior to a firing and/or drying process, and
to disintegrate or shrink during firing and/or drying process to allow the other elements of the kit to freely move.

12. The kiln furniture kit according to claim 1 , wherein
the base batt comprises limiting elements on its edges selected from the group consisting of a rim, pins, nibs, and a mixture of nibs and pins, and wherein
the limiting elements comprise the same material as the base batt.

13. A kiln furniture kit according to claim 1 , wherein
the base batt comprises a material selected from the group consisting of standard silicate, alumina, silico-aluminate, carbide, and mixtures thereof.

14. The kiln furniture kit according to claim 1 , wherein the one or more support segments are coated by a material comprising alumina, silico-aluminate, silica, magnesia, or mixtures thereof.

15. The kiln furniture kit according to claim 1 , wherein the perforations or wells have a substantially rectangular cross-section.

16. The kiln furniture kit according to claim 15 , wherein the substantially rectangular perforations or wells have rounded corners.
