Silica cloth is made by weaving either continuous filament or textured silica yarns which offer excellent protection from radiant heat and molten metal splash. Silica resists continuous temperatures up to 1000°C  in optimum environments. However, If exposed to high levels of abrasion and vibration the integrity of the fabric is lost at lower temperatures. Vermiculite dispersions can be added to improve resistance to molten splash. A light polyurethane coating can be added to one side of the fabric to aid fabrication and prevent fray.
