I have been using electromelts while vacuum casting for 30 years and
have never used a torch to melt metal so I guess I am somewhat
I strongly suggest you move on to the electromelt if you are vacuum
casting I suggest you buy the electromelt with the controller
option. This will make melting the metal much easier. The non
controller unit must be watched closely and you have to fiddle with
the temperature control knob to prevent the heating element from
Advantages of using an electromelt:
The temperature of the molten metal will be consistent between
pours. You can melt enough metal for several pours. I melt around 60
to 70 ounces of silver in my larger electromelt. The controlled unit
will hold the set temperature as long as you desire.
You are melting the metal in a reducing atmosphere. Pouring the metal
into the mold is like pouring coffee into a cup.
Disadvantages of using an electromelt:
It takes time to melt the metal. It takes about 40 minutes to melt a
charge of metal in the smaller electromelt and more than an hour in
the larger unit.
The graphite crucible will deteriorate in time. I find that I have to
replace the larger crucible after about 20 days of casting.
