Have materials to make thousands of RocCrock Stone Cookers. Purchase would include materials, machine used to manufacture product, boxes with logos, thermometers, marketing materials (video and paper), recipes and plenty of advice. Have been meaning to work on for years, hasn't happened, so am hoping someone else will have as much ambition, but take more action towards producing and marketing the product. It is basically a portable crock pot. Cooker works by heating Roc, placing in bottom of insulated pot and then placing pot of food on top of Roc and sealing with lid. Then you can drive, ski, hunt, fish, camp, etc. until you are ready to eat and you've got a hot pot of food ready to go. Would like to sell locally to eliminate shipping costs. Price is very negotiable.
