A moldable article, including at least a container made of a barrier material, the container providing an interior space within which a plurality of glass particles are contained. The glass has a glass transition temperature and a crystallization onset temperature, the difference between the glass transition temperature and the crystallization onset temperature is at least about 5° K., and the glass is composed of at least two metal oxides, from 0 to less than 20% by weight SiO2, from 0 to less than 20% by weight B2O3, and from 0 to less than 40% by weight P2O5. The moldable article protects the glass particles by keeping them clean and moisture free prior to a molding operation. A method of making a moldable article includes: removing entrapped moisture from a plurality of glass particles, placing glass particles in a receptacle, and sealing the receptacle to form the article. The moldable article may be placed in a mold and, during the molding process, the barrier material essentially burns off while the glass particles coalesce into a molded article. |
