Lost wood casting
I had a crack at something new today with amazing results. Lost wood casting. On a hunch I invested a magnolia seedpod in plaster/silica/glassfibre investment, burnt the pod out in a kiln and poured metal in the resulting cavity in the investment. For pictures of the result have a look here

I know that this is juvenile and not funny but, I cast the dice and lost my ass.

I've done insects in silver that came out well. Who's the handsome guy in the pix? Safety glasses and other gear would detract from that rugged image, I understand...a few good scars WOULD impress the girls! (nice work)
What can I say about safety. Chicks dig scars bones heal, you've got two eyes so 50/50 chance you'll still have some vision at the end of a bad days casting. Actually not my usual practice to not wear protection.
burn out was 685 celcius 50 degrees per hour ramp and a two hour soak time. The refractory really needs the glassfibre reinforcing as it becomes as brittle as heck.
