The industry's high-quality OptimaInvestment allows expansion ahead of resin patterns, and other high-expanding pattern materials. Therefore, it avoids flashing or cracking ofyour molds. Easy to mix formula creates a creamy, smooth, and pourableslurry. Extra low rise of slurry under vacuum. Provides a superiortemperature resistance for higher burnout temperatures. This package contains 30 lb.pattern materials including: .- Standard injection waxes.-Carving waxes.-Resin patterns (DLP,SLA) 3D Printed materials.- Wax based polymers.- Hybrid wax / plastic patterns

Review: This is a great investment - Works well been using it for years. Gold, silver, regular wax. High tech 3-D grows need some extra help. The H2O has Calcium Nitrate Tetrahydrate 76Grams per gallon, and the wax grows need to be dipped three times in React-Shun by Jett a Resin Casting Barrier. These work well
Review: Great - This investment handles resin burnouts extremely well. I've also dropped molds out of the furnace without them cracking. This is my go to investment for all silver, gold & base metal castings.

## Questions & Answers

**Q: Can I cast cobalt chromium at 1780 Fahrenheit?**
A: 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.

**Q: Can I use this investment to cast a  small bronze sculpture?**
A: I use this investment to cast resin models from my 3D printer. I cast bronze, but they are small parts.
