摘要:

ABSTRACTThe iron oxide content of an enamel glass was measured by the use of a predetermined curve representing iron oxide versus the index of refraction. It was found that the iron oxide content of the glass adjoining the interface between the enamel and the iron base rises sharply in the early stages of firing to a value close to the solubility limit of the glass after which it gradually falls to a constant value. The iron content at the surface remains low until that at the interface decreases, whereupon the surface concentration correspondingly increases. The cobalt additions resulted in a lower iron content in solution at the interface, but they increased the dendrite content of the glass. A decrease in the cobalt content resulted in an opposite effect. There was a direct relation between the amounts of cobalt and dendrites and the adherence. The effects of temperature and thickness of application are given, and the results are discussed.

摘要:

AbstractMany beverages contain dissolved COZ which is held in solution by pressure above atmospheric. To fill these products into pressure ware calls for mechanical systems which operate at pressures above atmospheric. The bottles are thus subjected to varying conditions of internal pressure during their filling. Because the ware is usually warmer than the product, there may also be some thermal effect. The action of the filling machine and the closure application may introduce some mechanical loading. The extent and timing of these conditions depend somewhat on the type of the filling apparatus, but the general limits may be stated to give some estimation of the service demands on the ware during this particular operation.

摘要:

AbstractThe properties of a series of low‐temperature bodies predominately comprised of clays and nepheline syenite are described. These bodies have a higher alumina content than the usual typical pottery bodies because of the high alumina content of nepheline syenite and clays and also because flint is introduced only in small amount

摘要:

AbstractFiring data were received from forty‐eight manufacturers of many types of ceramic products. The products were divided into six classes, and minimum, maximum, and average values are presented in chart form on the firing cycle, loading, heat consumption, and firing costs. Fuel costs are analyzed, and data are given for two small, electric, twin‐tunnel ki
