A large variety of objects is manufactured by dipping prepared fabrics in rubber solution. The solvents chiefly employed are benzene and mineral naphtha The rubber is rendered more readily soluble by undergoing previous mastication. Rubber shoes and galoshes are dipped by dozens at a time in tanks of solution and afterwards allowed to dry. Teats for feeding bottles are made by dipping glass moulds repeatedly in clear solution, with intervals for drying. Some of the smaller articles prepared in this way are vulcanised by the cold process, but for larger objects the sulphur required for vulcanisation is incorporated in the solution. For repairing motor tyres a quick-vulcanising mixture is employed, in order that the rest of the tyre may not be damaged by the heat required for vulcanising the mended area
