Alma, I have that exact one from Rio and I love it! I too thought I
wanted the one that poured out, but it was going to be far to heavy
for me to lift and pour. Also, if I'm not mistaken, that crucible
comes out so you must have to hold it in place somehow while
pouring--that just seemed a bit too dangerous for me to tackle. Just
a few notes about the Rio 1-Kilo Furnace:
1) It takes practice to get used to lifting the crucible out, but
the tongs aren't flimsy at all. The crucible has a groove and the
tongs fit right in them very securely.
2) I did many "dry runs" before I actually used it and found that it
is much easier if you grip the tongs with your palm facing the
ceiling (so gripping underneath the tongs). That way when you lift
and pour it is a more natural movement. That may seem obvious to
some, but the first few times I tried it I was gripping from the top
and had to rotate my arm in quite a bit during pouring--not very
3) The folks at Rio told me to add 50 degrees to the casting
temperature because the actual temperature of the metal is about
that much less than what the thermostat reads.
4) The crucible will cool quickly when you lift it out of the
furnace, so I keep a plumbers torch lit and in contact with the
mouth of the crucible when going from the furnace to the vacuum
table. It is just a foot away but the crucible does cool down
quickly! I had a bad pour the first time because I was using the
awkward hand placement and did not use the torch to assist.
Hope that helps!
