It's always fun to see video of a process in action! Last night I had my studio assistant take a short video while I poured a silver casting. It makes the process look so smooth & easy.
I've been doing vacuum casting for about a year now & have learned a TON....and I'm only just now starting to feel confident with it. There's always room to learn & I've definitely had my share of mistakes.
In the video, I remove the hot flask (has been cooking for several hours to get the wax removed & the flask up to temperature), while wearing gloves. It is set on the vacuum machine & the suction is turned on. Then I go over to my melting furnace, which has heated my metal to the right temp. I then pull out the removable crucible, and pour it right into the heated flask. Voila!
And here's the ring that came out of that flask! http://www.etsy.com/listing/51409895/calla-lily-ring
I'm super lucky to have access to an amazing arts center studio and that has been such an awesome experience to be a part of. It's in Lawrence, Kansas & I teach 3 classes there- metalsmithing (monday nights 7-9pm), Open Studio, and Lost wax casting (wednesday nights, 7-9pm).
