<p>A method of firing glazed articles in a continuous kiln in which the temperature of the articles is raised to a firing temperature at which the glaze becomes molten, comprises subjecting the articles to direct heating in the region of the kiln in which they are raised in temperature towards the firing temperature, subjecting the articles to indirect heating in the region of the kiln in which they attain the firing temperature, and directing products of combustion from burners employed to generate the heat in the indirectly heated region into contact with the articles at or before direct heated region to preheat the articles.</p> |
