ABSTRACT:
A method of manufacturing a vitreous enamel body includes forming particles of vitreous material and melting to fuse the particles together to form the body. The particles of vitreous material are spherulized and are selected as to their granulometric properties according to the degree of compaction required in the finished enamel body. From 20% to 40% of the bulk volume of the mixture is a fine particle size fraction. Such a finished enamel body may be a coating, for example a high-compacity enamel coating on a bathtub, or it may be a self-sustaining body, for example a porous vitreous filter element. Porous coatings and compact self-sustaining bodies may also be made.
