It depends on how much ice you have
The term is actually "plastic", and many substances fit into that category, such as butter, tar, glass, iron.
no
Heat the material till it melts, add molten material, let it cool. Plastic, glass, metals are all "welded".
no it just melts.
First, not all plastic melts, secondly the fact of something melting has nothing to do with its electrical resistance.
The temperature at which glass melts is highly dependable upon it's chemical composition but average glass melts between 1400 and 1600 degrees Celsius.
because plastic melts.
Melting plastic is tricky because you can easily char or burn it and can be dangerous because of the fumes released when the plastic melts. Also, different materials melt at different temperatures which can also make it difficult. If you have access to a pottery kiln, you could try putting the plastic in a kiln-safe container and melting it that way. However, it is unknown what will happen if you do so. Either way, I would not suggest melting plastic at home, just re-use it for something else or recycle it.
It melts and gets hard
