The first step in working in ceramics is the finding of a plastic clay body. In the past, potters had to dig their own clay from locally available sources as there were no other options. Some potters still dig their own clay and feel a valuable connection to the earth through this process.

Ceramic forming techniques are ways of forming ceramics, which are used to make everything from tableware such as teapots to engineering ceramics such as computer parts. Pottery techniques include the potter's wheel, slip casting and many others.. Methods for forming powders of ceramic raw materials into complex shapes are desirable in many areas of technology.

Slip casting technique is used for shape forming ceramic slurry - a stable suspension, consisting of ceramic powders, processing additives and 20-35% of liquid (water or solvent). The slurry is poured into a mold made of a micro-porous material (e.g. gypsum), which is capable to soak the liquid from the slurry, consolidating the ceramic part.

Methods for reducing the costs of processing steps in preceramic polymer processing routes for non-oxide fibers should be pursued. For example, spinnable, low-cost polymer precursors that cross-link (cure) rapidly on line or thermally cross-link in the early stage of pyrolysis have the potential to increase throughput and lower costs.

Ceramic glaze is an impervious layer or coating applied to bisqueware to color, decorate, or waterproof an item. For earthenware, such as fired clay pottery, to hold liquid, it needs a glaze. Potters apply a layer of glaze to the bisqueware, leave it to dry, then load it in the kiln for its final step, glaze firing.
