Can I cast cobalt chromium at 1780 Fahrenheit?

To increase the chances of a successful cast you should have a temperature of 15 to 30 degrees above melting point to increase the chance of a smooth pour. Cobalt melting point is 1330c/2430f. So for a smooth pour you'd want 15 to 30 degrees above that,depending on you number or size what what you want to cast. I run a jewelry shop called Rockbottomjewelryco.com if you have any questions on jewelry creations steps.

Can I use this investment to cast a small bronze sculpture?

I use this investment to cast resin models from my 3D printer. I cast bronze, but they are small parts.
