Definitions

  • a process for the produc- Linium 921 tion of a glossy coating on a support comprises Cobaltous carbonate 4 applying to the support a composition obtained by fusing together boric acid or boric anhydride and lead. oxide, heating the composition until This mixture is fused, run off and crushed as in the preceding example. When heated, it it vitrifies and then immediately withdrawing gives a glossy black waiting as scan as i the mated quppgrt from thn source of heag a peratnre of 23G-3G0 C.
  • Examples are alkaline phos- 40 Escample III nhates or the oxides of zinc, nickel cobalt, tin, r, i .h' re are there hl mire aluminum or silicon employed, either separately 5 y d g Parts or ll).

  • Example IV Parts Boric acid 17.8 Minium 92.1 Tin oxide 2
  • the mixture melts at 300 C. and commences to recrystallise at about 350 C. (in the absence of tin oxide, crystallisation follows shortly after fusion at 300 C.) It then melts in stable fashion at about 450 C.
  • Parts Hydrated boric acid 17.8 Minium 92.1 Kaolin 4 The ingredients are fused until completely homogeneous and the resulting composition is run off and cooled. The composition is then crushed and applied to a suitable support. Upon heating, it is found that a glossy and stable coating is formed as soon at a temperature of 300 C. is reached, and this coating can be brought to higher temperatures without destroying the gloss of the coating. In contrast. a similar mixture which does not contain any kaolin is devitrified as soon as it is heated to a temperature slightly 7 above 300 C.
  • Process for the production of glossy coatings on supports selected from the class consisting of earthenware and metal supports which comprises applying to the support a layer of a particulate fused composition consisting to the extent of at least 95% by weight of a mixture of lead oxide and boric oxide and to the extent of 0.5 to 5% by weight of a stabilizing agent containing an oxide selected from the class consisting of the oxides of zinc, nickel, cobalt, tin, aluminum and silicon, the ratio of boric oxide to lead oxide in the composition being of the order of 1:9, heating the support thus coated up to the temperature at which the composition first vitrifies and then immediately withdrawingthe coated support from the source of heat.
