Bond clays explained for glass refractories and graphite crucibles, with practical testing and use guidance.
This volume compiles methodical testing results and practical insights on plastic bond clays. It covers how water content, drying shrinkage, porosity, and strength relate to performance in firing and in high-temperature service. The text explains how to evaluate slaking, modulus of rupture, and burning behavior, and it discusses how composition and processing affect the density, refractoriness, and resistance to overfiring. A substantial portion is dedicated to the use of bond clays in graphite crucibles and in glass-refractory bodies, including material selection, mixing, drying, and firing practices.
Readers will gain an understanding of how to classify clays by strength and porosity, how to adjust formulations with kaolin and grog, and how different clays influence the stability and life of high-temperature pots and crucibles. The work also provides historical context on ore sources, material purity, and practical considerations for reliable manufacturing.
- Clear testing procedures for plasticity, shrinkage, porosity, and strength
