detail : the softening point is noticed when the tip of the cone starts bending with the rise of the temperature. In practise it has been observed that the higher the alumina content in the fireclay, the higher is the fusion point. All fireclays are not necessarily plastic clays. In such cases, some plastic clay, like ball clay is added to increase platicity to a suitable degree. A good fireclay should have 24-26% plasticity and shrinkage after firing should be within 6-8% maximum. It should also not contain more than 25% fe2o3. It has been observed that some clays lacking plasticity when allowed to 'weather', i.e. Left in the open for a few months, become plastic due to the formation of humic acid in the clay. Non-plastic fireclay is also known as flint-clay. It may be called semi-flint and semi-plastic depending upon the degree of plasticity.
