Cristobalite

For Low Fusing Crown and Bridge Alloys

The principal ingredient, CRISTOBALITE, gives high thermal expansion, even at comparatively low temperatures. It is possible to use the same creamy mix by simple standard vacuum or painting techniques for all types of inlays.

The usual Whip Mix care in compounding and control assure a uniform water/powder ratio and consequent uniform expansion.
