To-day there are lots of choices for getting colorful designs onto porcelain china. Some, like decoupage, waterslide stickers and air-dry shows like Delta Air-Dry PermEnamel are within-the reach of any house crafter. Others, like dye sublimation printing, transfer printing and hand-glazing high-fired pottery require substantial investment in equipment and are best suited to well-capitalized businesses and artists cooperatives. The two classic means of putting patterns onto pottery, hand-painting and transfer printing, still exist today. Furthermore, there is a version of water-slide decals used commercially which consists of implementing the decals to the porcelain and screen-printing decals with glazes. In each case, the pottery is high-fired before decorating to a minimum of cone 6. [Cone can be a way of measuring heat absorption resulting from heat applied over time. To compare more, consider having a glance at: cheeseflesh45's Profile | Armor Games . Cone 6 means between 2165 and 2269 degrees F (according to how fast the kiln cooks or ramps up ).] Such high-firing creates the hard almost-translucent quality of real porcelain. Then the piece is adorned and carefully fired repeatedly to melt and fuse the glazes to the porcelain. Incidentally, the term porcelain is used more and more extensively as new practices developed. Ask any potter to establish porcelain and he'll likely give the classic definition to you. To a potter, true porcelain is high-fired (cone 6 or higher) white clay that is at least significantly translucent. It has a big proportion of kaolin clay, with the remainder being largely feldspar and silica. This clay structure accounts for the pure white gleam of porcelain.

Merchants who paint pottery (instead of can even make it) reference three qualities of bone china, and porcelain: hard-paste, soft-paste.

They all include kaolin but only hard-paste has silica and feldspar and is high-fired. The high temperatures cause the body and the glaze to blend. When hard-paste porcelain is broken, it is impossible-to identify the body from the glaze. Soft-paste porcelain brings ground glass or frit (material for glass that's not-yet fused and vitrified) and is shot to between 1 and cone 01 (1999 to 2109 degrees F). Since soft-paste porcelain is fired at lower temperatures, it generally does not fully vitrify and remains slightly porous. When soft-paste porcelain is broken, you are able to distinguish a human anatomy covered with a glassy layer of glaze. Bone china has bone ash added to the kaolin and vitrifies (becomes glass-like) somewhere between cone 2 and cone 5 (2034 to 2205 F). Bone china is more durable than soft-paste porcelain, though much less difficult as accurate porcelain. The bone ash significantly escalates the translucence of the porcelain. Finally, go to a tile store and have a look at their porcelain tiles. You'll see base clay including white to brown to gray, if you turn them over. The meaning of porcelain in the tile industry has nothing to do with the clay content or degree of heating. Rather, tile companies determine as porcelain any tile dismissed to the point where it absorbs significantly less than 3% water.
