Claim 13
Independent Claim
91 words
The method for forming an ignitable coating on a charcoal briquette, comprising the steps of: mixing a flammable alcohol, gum cellulose, and a wicking material selected from the group consisting of expanded perlite and expanded hydrobiotite in particulate form to form a gel mixture; submerging the briquette in the gel for a period of time between one and five minutes; removing the briquette from the gel mixture and draining the briquette; and, subjecting the coated briquette to a temperature in the range between -10° and 32° F. to solidify the coating.
