During pottery, the dried clay can be polished before it is fired. After the raw firing you should refrain from grinding. The specific porous consistency of the material is substantially damaged in almost all cases. Theoretically, grinding with the highest-quality diamond grinding heads is possible.

If larger bumps are removed and compensated in the leather-hard condition, a longer polishing is recommended, if necessary with moistening with a water spray bottle. For clay works that are already fired, mechanical smoothing is no longer possible. Ansch Glaze glazes only superficially

glazes consist of several layers. As with human skin, the retention of the surface decreases with each layer loss. If glaze is to be sanded, the removal should concern only the upper layer if possible. Under no circumstances may be penetrated to the "naked" tone under the glaze.

Similar to drilling sound, every mechanical action and change places substantial stability at risk. If sanding is required, this risk can be reduced by manual labor. Electrically operated devices are usually not "sensitive" enough lead.

Smoothing and polishing by polishing

Clay is polished before raw blasting, also known as pre-shredded, to achieve shine and smoothness of the surface. The ideal time is when the clay still looks moist but has already dried to a leather-hard finish. As a polishing tool, stones such as the semi-precious stone agate and very smooth pebbles are good.

Other possible polishing aids are metal spoons or plastic films wrapped around a support. Typical examples are cling films or shopping bags, which are stretched around a brush or disposable hand.

Tips & TricksIn principle, you must assume that your sound can not be changed after firing. Therefore, it is necessary to influence the surface textures even at the stage of formation.
