Abstract
A silica refractory structure may be added to, e.g. by way of repair, in a working environment at a temperature in excess of 600.degree. C. Such addition is made using one or more vitreous silica bricks bonded into position by projecting a mixture composed of finely divided particles of exothermically oxidizable material, e.g. Si optionally with Al and particles of silica, and burning the mixture during its projection to form a coherent refractory mass which bonds the addition together and to the original structure.
