Abstract
Glass compositions suitable for pot and marble fiberization display excellent chemical resistance to both acids and moisture while being highly biosoluble at the same time. The glass compositions are characterized by ratios of components which are reflective of acid resistance, biosolubility, and moisture resistance. Preferred glasses have a difference between HTV (10.sup.3 poise) and liquidus greater than 500.degree. F., and a biodissolution greater than about 350 ng/cm.sup.2 /hr.
