Fibrous metallic and/or non-metallic materials are coated with a dispersion of a heat-resistant substance in a liquid which vapourises at an elevated temp. The liquid is vapourised from the coating and the remaining substance is subsequently fused. Specifically suspensions of solder and/or enamel and/or silicates and/or borates and/or phosphates may be used.
