Paper Abstract

Cold wall melting with high frequency induction heating has the advantage that no impurities are introduced in the glass during the melting process. Different types of optical glasses were tested. With one exception all optical glasses took power in the high frequency electric field in the range from 0.5 to 3 MHz at a sufficiently high temperature. A good correlation between the electrical conductivity of the glass melt measured with 10 kHz and the penetration depth of the electrical field can be found.
