<human>:  Would a compact disc melt in magma?
<bot>: Yes, a compact disc would melt in magma. Magma is the molten material beneath the earth's surface. The temperature of magma ranges between 1300F and 2400F degrees. A compact disc is made of polycarbonate plastic. Polycarbonate plastic melts at 311F degrees. So a compact disc would melt in magma.
