<p>A glazing layer is formed on the surface of an oven refractory by applying thereto a glaze having a melting point of 900 °C or below and comprising, on the oxide basis, 0-10 wt.% of Li2O, 0-10 wt.% of B2O3, 10-40 wt.% of R2O (wherein R represents Na or K), and the balance consisting of SiO2, thereby preventing the growth of scale on the wall of a high-temperature oven, repairing damaged parts, and preventing the deposition of carbon on the inner wall of a coke oven, a carbon firing furnace or the like and on the oven attachment such as an oven lid or a gas pipe.</p> |
