Sandblasting is a quick and easy way to restore old rusty cast iron cookware.
You can cleanup nice pieces from goodwill, or ones in your own kitchen that have gotten a little neglected.
The following video shows all steps necessary. It takes about 10 minutes total.
I made it at Techshop SF!
Step 1: Watch the Video Tutorial to See How It's Done!
This video tutorial will take you through all the necessary steps.
I made it using the Camtasia Screencasting software. I'm trying out their free 30-day trial to see if it can help me make better instructables.
Step 2: Seasoning
You will want to "cure" or "season" your cast iron piece after sandblasting. This entails covering it with an (edible) oil, and baking it so that the cast iron has a nice fat layer to seal it and therefore protect it when cooking.
Google "how to season a cast iron skillet" and you'll come up with lots of specific suggestions of how to do this.
