Abstract
A fire resistant cigarette has a wrapper having a coating applied as a dual treatment comprising the separate steps of coating the wrapper with a solution of an alkali metal silicate and coating the wrapper with a pH lowering material wherein the pH lowering material lowers the pH of the alkali silicate. The dual treatment of the cigarette is such that when the cigarette is smoked it produces a smoke which has a pleasing taste and the cigarette is fire resistant.
