A foamed glass product and its manufacturer are disclosed. According to the present invention, crushed glass particles and a foaming agent, preferably selected from CaCO.sub.3 and CaSO.sub.4, are provided. The glass particles and foaming agent are mixed and heated to a desired foaming temperature for creating foamed glass. A nonreactive gas having desired insulative properties, preferably selected from SO.sub.2 and CO.sub.2 is provided to sweep air away from the mixture during heating.

Foamed glass manufacture

A novel process is disclosed for producing a fracture-free shaped ceramic green body which comprises casting an aqueous suspension of hydroxylapatite, whitlockite or a mixture of these having a high water content and high drying shrinkage in an impervious mold, the cavity surfaces of which are coated with an inert water-immiscible lubricant; drying the casting under controlled conditions of temperature and humidity and removing adsorbed lubricant from the resulting dried green body.

Ceramic forming process

A lubricant for forming a ferrous metal blank into a preselected configuration by warm- or hot-forming procedures. The lubricant is an alkali-modified borate glass containing a minor mole percent of an alkali metal oxide, preferably sodium oxide. The glass is formed in situ on the surface to be lubricated by depositing on the surface a glass-forming mixture of a source of boron oxide and an alkali metal borate and then heating the mixture to form the glass.
