This invention relates to the production of carbon black by means of an incomplete air-acetylene combustion reaction. The apparatus comprises heating means arranged around an acetylene jet and arranged to cause heat cracking of the acetylene molecules prior to the combustion reaction. The invention is applicable in particular for forming linings for facing moulds or the like used in metallurgy or glass-making, for forming insulating facings on conveying elements and for lubricating drawing heads.
