Abstract: A toe warmer assembly attaches to a foot to warm toes directly or through footwear. The assembly includes a pouch having a closed end, an open end, and a perimeter wall extending from the closed end to the open end defining an interior space. A flap extends from the open end of the pouch and is selectively positioned extending over the open end wherein the open end is obstructed by the flap. A first strap has a first end coupled to the pouch and a second end coupled to the pouch wherein the first strap forms a first loop extending from the pouch. An exothermic member is positioned in the interior space of the pouch wherein the exothermic member delivers heat through the pouch.

Abstract: A ceramic raw material essentially contains a pre-formed leucite filler which is obtained by reacting alumina, silica and potassium carbonate and/or oxide at a temperature of at least 1149.degree. C, and nepheline syenite. A leucite-nepheline syenite ceramic raw material which is useful as a dental porcelain powder contains 14 percent by weight of sodium-, potassium-, and lithium carbonates and 86 percent by weight of a 5 percent leucite/95 percent nepheline syenite mixture.Upon fusing of the ceramic raw material of the invention, ceramic bodies are formed which have a crystalline leucite phase dispersed in a matrix of a glassy nepheline phase and any other constituents of the ceramic. The leucite provides the ceramic bodies with desirable properties of controlled thermal expansion and high strength.
