fusible

The kaolin is not fusible, the petuntze vitrifies and envelopes the kaolin, producing a smooth compact body which is translucent.

Slender, brilliant, colourless needles; fusible at 122 Fahr., and distilling at a higher temperature without decomposition.

All the fusible plugs were in cartridges to prevent sparks from falling if the plugs burned out.

There was a safety valve, a glass water gauge, a pressure gauge, and two fusible plugs upon the tube.
