Last night I cast for the very first time...here are pictures for your viewing enjoyment:
Lighting the torch - GOOG (on: gas, oxygen; off: oxygen, gas)
Heating the crucible before adding the silver. You can see the flame shooting out of the spout on the right. This is where the melted silver will flow out into the mold.
Stirring the molten silver just before pouring into the mold. Silver melts at just over 1700* F. Once the metal was poured, we let the mold sit for about 30 minutes and then quenched it in a bucket of water.
The finished castings! The three rings are all attached to a large "button" (the center ring) which will be recycled and used in another cast. The silver is dirty due to the firing process and needs to be cleaned up. The sparex in the pot will remove most of the oxidation, but these rings will still need a little TLC before they are wearable. Next steps: clean, buff and polish...

Yeah nice post,A hot wire welding torch assembly includes a non consumable metal electrode 12, a filler metal 6 fed to a weld puddle 11 foamed by an arc 10, a collect body 15 for holding the electrode, a shielding gas nozzle 3, and a torch body 1 molded from a synthetic resin for co axially mounting the collect body and shielding gas nozzle.
