Porcelain laboratory
ware is very popular during the chemical-analytical tests and different kinds of support work in chemical analysis, as well as in clinical diagnostic laboratories.

Porcelain - a material made from a mixture of several substances: kaolin (white clay), quartz, feldspar and other aluminum silicates. Almost always the porcelain in the manufacturing process are covered by a very thin layer of a special glaze - it improves abrasion resistance, and moreover, resistance to corrosive acids and bases. The major advantage of porcelain, when compared with glass, can be called thermal resistance and mechanical strength. Superhard variety of porcelain, which are used for the manufacture of glassware for laboratories without a covering glaze withstand heat up to 1300 degrees, while the porcelain covered this glaze softens already at 1200.

All glassware porcelain highly resistant to hot acids. Exposure to hydrofluoric and phosphoric acid - an exception, they destroy the porcelain. Concentrated solutions of alkali when heated destroy porcelain.

Funnel Buchner funnel or baffle, used in laboratories for carrying out filtration processes of chemical solutions under reduced pressure (vacuum) through filter paper. All surfaces of this funnel, excluding only the top edge covered with a thin layer of glaze.

Mugs, cups, porcelain cups have a different capacity. The inner and outer portions thereof, excluding the bottom outside, covered with a solid coating.

Pumps that are used for the combustion of organic matter, as well as to determine the level of carbon content in the steel composition made from a heat-resistant porcelain. Boats vary in shape and covered with glaze.

Quite often, porcelain spoons are used in laboratories. For the grinding of materials - mortar. For a porcelain mortar and pestle is attached. High strength porcelain makes it possible to produce from it as crucibles and spatulas.
