Types of Clay for Pottery – The 5 Main Types of Ceramic Clay

The reason that ball clay is so plastic, is to do with particle size. A key ingredient in ball clay is the mineral kaolinite. This is an important ingredient in most clay bodies. However, what distinguishes ball clay from other clay bodies is its particle size. Ball clay is made up of very fine clay particles or clay crystals.

Whiting – Highwater Clays

Whiting is previously referred to as #1 White. It is a source of calcia preferred for use in glazes. Whiting has traditionally been a source of CaO in raw glazes and glass. (However, whitings also typically contain some dolomite as a contaminant.) Whiting is generally inexpensive, and there is a large calcium carbo

Zeolites and modified clays in environmentally sustainable ...

2019-1-1  12.1. Introduction. Zeolites and modified clays (MCs) have been used as components in modern building materials since at least the 1980s, when the introduction of zeolite-rich tuffs in cementitious materials was proposed for the first time (Komarneni and Roy, 1983, Sersale and Frigione, 1985).The aim of this chapter is to overview the many different uses (actual and potential) of zeolites
