A wide range of prehistoric artifacts were formed by pecking, grinding, or polishing one stone with another. Ground stone tools are usually made of basalt, rhyolite, granite, or other macrocrystallineigneous or metamorphic rocks, whose coarse structure makes them ideal for grinding other materials, including plants and other stones.

Grinding ceramics is also best done with fluid coolant that lubricates the region being ground. For sintered ceramics it is best to use resin-bonded wheels with either synthetic or natural diamond of different grit size pressed at different concentrations in polymer resin.

Next, start grinding the glaze down with a coarse grinding wheel or grinding attachment on a rotary tool. Slowly grind down the glaze until the foot looks uniform in shape again. After the rough grind, switch to a fine grit sand paper to polish off any sharp edges. Here's a quick video of grinding off a glaze run from the foot of the pot.

How ceramics are made? Ceramics: Ceramics are made from clay and composed of aluminium silicate mixed with sand. The white clay used to make ceramics is kaolin which is rich in kaolinite or hydrated aluminosilicate, Al 2.O 3 2SiO 2.2H 2 0.; Red clay consists of iron(III) oxide which gives the red colour.

Pottery may come out of a bisque fire feeling rougher than it did before it went in. This is normally the case for clay that contains grog or sand. The reason for this is that grog is clay that has already been fired and ground up into granules. Grog has already gone through the shrinking and densification process.
