The Effects Of Sodium, Barium And Calcium Chloride Upon The Physical Properties Of A Whiteware Body, William Newton Coffman Jan 1934

The Effects Of Sodium, Barium And Calcium Chloride Upon The Physical Properties Of A Whiteware Body, William Newton Coffman

Bachelors Theses

"The wide spread use of American kaolins and ball clays has been frowned upon by the majority of white-ware manufactures because the product resulting from their use in most cases has a color which is inferior to ware produced from English raw materials. This inferior color is generally attributed to the presence of a small amount of iron in the American clays. If some inexpensive chemical addition could be made which would eliminate the iron stain or in some way mask it, a wider market could be found in the white-ware industry for the domestic clays. One way to eliminate …


A Comparison Of Florida, Georgia And G-1 Kaolin As The Chief Clay Ingredient For A Sanitary Ware Casting Body, George Armour Sellers Jan 1934

A Comparison Of Florida, Georgia And G-1 Kaolin As The Chief Clay Ingredient For A Sanitary Ware Casting Body, George Armour Sellers

Bachelors Theses

"The purpose of this investigation, originally, was to determine the suitability of substituting G-1 kaolin for Florida kaolin in a sanitary ware casting body. It was later extended to embrace a comparative study of Florida, Georgia and G-1 kaolin as the chief clay ingredient in a sanitary ware casting body"--Introduction, Purpose of the Investigation, page 1.


A New Theory Of The Spalling Of Fireclay Products With Relation To Thermal Expansion, Robert Legrande Stone Jan 1934

A New Theory Of The Spalling Of Fireclay Products With Relation To Thermal Expansion, Robert Legrande Stone

Bachelors Theses

"There is one factor that is responsible for much of the failure of refractories in furnaces and other metallurgical processes and boilers, namely spalling. Many times this action has been the cause of roofs to cave in, side walls to slump, and bungs to fail. Consequently it is a factor that is of utmost importance. The erosion and slag effects are also of greatest importance to refractory stability. Spalling, as referred to refractories, is defined as the breaking or crushing of the unit due to thermal, mechanical, or structural stresses, presenting newly exposed surfaces of the residual mass. Taking the …
