BARBECUE BRICK ABSTRACT A method of manufacturing a barbecue brick comprises the mixing of organic and/or inorganic material with a silicate solution which binds the various constituents and prevents combustion of the brick. The mixture is cast into moulds, cured and cut to the desired brick sizes. The cut bricks are then heated, thereby causing charring of the organic particles and frothing of the silicates. The organic material comprises wood particles and the inorganic component is made up of refractory material such as fire clay or alumina-silica. The silicate solution comprises aqueous sodium silicate and/or aqueous potassium silicate. The bricks manufactured by this method are characterized by a high porosity which serves to prevent fluids, resulting from the cooking of meats, from dripping on to the gas burners. In this manner, these bricks prevent fouling of the barbecue and the burners. In addition, flaring, which occurs as such fluids are combusted over the burners, is also prevented. A further method is provided for treating known barbecue bricks to increase their surface porosity.
