An investigation of the fundamentals of the adherence of porcelain enamels to metals indicated that good adherence is the result of metal-to-metal bonds between the atoms in the base metal and the proper metallic ions in the enamel. To accomplish thi

The effect of particle size on the reflectance of thin semitransparent layers, such as enamels, was studied by using mixtures containing opacifying particles of definite sizes in an oil of known index of refraction. The mixtures were applied on a bla

The solubility of zirconia at 1500° and at 2200°F. was determined for glasses containing Na2O, B2O3, Al2O3, and SiO2. The solubility at these same temperatures was also determined for glasses containing equal parts of boric oxide and silica and one

Using X-ray and microscopic technique, a detailed examination was made of the effect of smelting time and temperature on the crystalline material causing opacity in typical superopaque antimony enamels. It was found that, although the crystalline ant

The reactions taking place during the smelting of a typical superopaque antimony enamel were studied by first determining the thermal effects which occur during the smelting of the raw batch and then by investigating the reactions which produce these

Glass compositions containing antimony oxide as a glassformer were developed. The stabilizing oxides used in these compositions were A12O3, Na2O, and K2O. Glasses formed from these oxides, containing antimony oxide in amounts up to 78% by weight, tra

Five clays used to suspend porcelain enamels and their properties were studied. Fundamental data were first obtained on the clays, which were then milled in different proportions with several types of porcelain enamel frits. The properties of the res

A group of enamels containing fluorspar, cryolite, and sodium silicofluoride, added in various proportions, was prepared under carefully controlled conditions, including smelting in an electric resistor furnace. The only mill additions were clay and

It was first shown that the enamel slips which have the best suspnding characteristics contain equal amounts of Na2O and B2O3 and at least a moderate amount of NaF. The solubilities of mixtures of Na2O, NaF, and B2O3 were then investigated. The pH of

The microscopic appearance of sheet-iron, white cover enamels indicates that mill-added opacifiers function principally as layers between the frit particles and do not diffuse well into the enamel. This explains the reasons why (1) mill-added opacifi
