Abstract

PURPOSE: To obtain a melting crucible in which heating and melting are smoothly carried out by assembling a flat bottom, a conically expanded surrounding wall which is thinned upward and a horizontal flange.
CONSTITUTION: Bottom 2 of melting crucible 1' is flattened, and conically expanded surrounding wall 3 is smoothly joined to the peripheral edge of bottom 2. Bottom 2 is made thicker than wall 3. Wall 3 is gradually thinned upward, and a horizontal flange is put on the upper edge of wall 3. In this melting crucible a glass bead sample is smoothly heated and melted. The deformation and consumption of the crucible are controlled to elongate the life.
