Faience, what is it?
The composition of the faience material itself has the same components as porcelain , only in a different ratio. This base mix consists of kaolin (white, fire-resistant clay), quartz and feldspar.
A diverse composition, in combination with other elements, is divided into four types of earthenware:
  • solid;
  • soft;
  • feldspar;
  • calcareous type.
The high content of clay and special technology of firing allows you to create earthenware dishes, which has its own technical characteristics. For its production most often used solid type of earthenware. This material has a finely porous structure, which undoubtedly improves its functional qualities.
Cookware from faience absorbs moisture over time and even becomes a little more than its original volume (although it's hard to see at a glance). This leads to the appearance of small microcracks on the surface of the entire glaze in the form of a thin web-cobweb. This feature adversely affects the service life of the object, since its surface is destroyed, forming large cracks and chips. For the same reason, faience vases may start to "leak" or leave a mug and a cup with a "wet" footprint.
Why then do they like earthenware? For the brightness of colors, "reliability" of forms and cheapness. Low firing temperatures for earthenware products allow the use of a wider color palette when painting. Often, objects have a bright, juicy range in the drawings, which, of course, can not not like. Although currently there are many white faience.
Another earthenware dishes is massive and smooth forms. Its "article" stout tureen and weighty herring bowl with salad bowls look more reliable than thin-walled porcelain. And this feature is not unnoticed by practical hostesses.
