The prototype die has been assembled and heating experiments initiated. These indicated that with Cairod heating a die face temperature of l300 F can be obtained. This will be supplemented by gas flame radiation heating on the die face to attain a temperature of 2400 F. Experiments utilizing calcium flouride-sodium flouride salt combinations to give oxidation protection to the refractory metal die components were successfully performed. A spectrum of viscosities can be obtained with this salt combination by relatively minor adjustments in proportion of either of the components.
