While advancements in machining techniques have improved the processing of ceramics, challenges remain. The inherent brittleness of ceramics can lead to cracking and chipping during machining, necessitating careful optimization of cutting parameters and tool selection. Moreover, managing heat generation is crucial; excessive heat can cause thermal shock and degrade the material properties.

2. Mixing the Mold Material A mixture of fine sand and plaster is prepared, ensuring the correct proportions to achieve the desired consistency. The plaster is typically mixed with water, and fine grains of sand are added to create a blend that will retain shape yet allow for easy removal of the mold.
