    an electromelt is an electronic melter which is basically a steel and
    ceramic chamber on a base which holds an elongated crucible in it.
    You can get programmable or manual melters. I bought one of the
    programmable rio ones and really love it! I hated using a blow torch
    when I did casting earlier. With this one, I set the program to go
    to a certain temperature and hold...put the silver in it w/ a little
    flux, and wait until the temp gets up to melting temp, open and stir
    to get out the crud, let it continue up etc. When I'm ready to cast,
    I simply take out my flask from t he kiln and put it on the vacuum
    platform and start it, when the vacuum is at full, I simply remove
    the crucible and pour it into the flask...no scary blow
    torches...much more relaxed. Also, with doing filigree, I needed to
    superheat the silver so it would stay molten long enough to fill the
    flasks, and with an electromelt, you know when it's reached the
    right temperature. I'd guess it's more suitable to vacuum casting
    than to centrifugal, though I believe there are some centrifugal ones
    with built in electromelts.
