Playing With Hot Molten Metal

In last weeks lost wax casting class at the Creative Arts Center I invested 3 small wax sculptures. This week it's time to pour hot molten metal!
The wax sculptures have been melted out of the investment leaving behind a hollow space inside the very, very hot flask.

Now it's time to  slip on flame proof gloves and welding goggles, pull out the torch, and melt some bronze. This takes about 5 minutes.

Once the molten bronze starts to swirl around in the crucible it's time to pour. Note the orange stream of bronze going into the flask. Hot, Hot, Hot.

It's in there, and it should have filled ALL the hollow areas... Let us pray... In lost wax casting you can work hours and hours on the wax sculpture, just to loose everything in that .05 seconds of poring.

And here they are! 3 small almost perfect bronze sculptures!!! There are a few nubs and surface burps that will be removed when I take off the casting sprues. Then, well then we move on to polishing. This is not a quick process.
