Abstract

See full text

Provided are ceramic compositions and containers, in each case comprising a ceramic (e.g., porcelain, stoneware, porcelain, or ceramic composition having properties of both) composition to which an amount of alumina has been added to provide a ceramic composition comprising 20% to 25% (wt./wt.) alumina, preferably about 22% (wt./wt.) alumina, providing a stronger material, such that wall thicknesses (e.g., of double-walled beverage containers) can be reduced or minimized to create a lighter double-walled ceramic container. The disclosed containers have a chemical and porous structure suitable for a wide array of stoneware glazes, and display water absorption rate properties comparable to stoneware. Methods of making same are provided.
