Abstract: Refractory investment material and method for forming a positive replication of a tooth structure on which a high-alumina based porcelain tooth restoration is to be formed, the material being formed from a refractory powder which includes calcined alumina mixed with a liquid carrier comprising an aqueous colloidal dispersion of silicon dioxide. The method comprises the steps of: preparing a negative impression of the tooth structure on which a tooth restoration is to be placed; forming a positive replication of the tooth structure by pouring the mixture of refractory powder and aqueous dispersion into the negative impression; allowing the positive replication to harden; removing the positive replication from the negative impression for degassing and cooling; and coating the positive replication with a mixture of high-alumina porcelain in an aqueous carrier to form a core layer of porcelain on which subsequent layers of high-alumina porcelain may be applied.

Abstract: A container for rapidly cooling and holding foods at safe temperatures for extended periods of time which includes an upwardly opening inner container in which foods may be placed and another container surrounding the inner container. An enclosed chamber is formed between the bottoms and side walls of the inner and outer containers and is provided with a slow-to-freeze, slow-to-thaw gelatinous material which may be frozen by placing the container in a low temperature freezer. The container is further characterized in that the bottom and walls of the inner container provide insulating properties which control the rate of heat transfer between the gelatinous material, when frozen, and foods placed in the container and further characterized in that the bottom and walls of the outer container provide insulating properties which substantially retard heat transfer between the gelatinous material, when frozen, and the ambient air which surrounds the container.
