PUTTING PATTERNS ON PORCELAIN

soon there are many options now putting colorful patterns onto porcelain china. Some, like decoupage, waterslide decals and air-dry paints like Delta Air-Dry PermEnamel are within the reach of each home crafter.

Others, have fun dye sublimation printing, transfer printing and hand-glazing high-fired pottery require substantial investment in equipment also are best suited to well-capitalized businesses further artists' cooperatives.

The two classic ways of putting patterns onto porcelain, hand-painting and transfer printing, still exist today. In addition, there is a high-tech version of waterslide decals used commercially which consists of screen-printing decals curtain glazes again requesting its decals to the porcelain. magnetism each case, the pottery is high-fired before decorating to during least cone 6. [Cone is a measure of heat absorption resulting from heat applied over time. Cone six translates to between 2165 and 2269 degrees F (depending upon how fast its kiln heats-or ramps-up).] Such high-firing produces the hard almost-translucent quality of true porcelain. Then the piece is decorated and lightly fired repeatedly to melt and fuse the glazes to its porcelain.

Incidentally, the term 'porcelain' has been applied more and fresh broadly over new techniques developed. hunt for any potter to define 'porcelain' and he will likely give you the classic clarification. To a potter, genuine porcelain is high-fired (cone 6 or higher) white clay that is at least somewhat pellucid. It has a large equate of kaolin clay, with the atavism being primarily feldspar again silica. This clay composition accounts for the pure torrid gleam of porcelain.

Artisans who paint porcelain (rather than actually make it) refer to 3 grades of porcelain: hard-paste, soft-paste, and bone china. They all contain kaolin but only hard-paste has feldspar and silica and is high-fired. The high temperatures cause the body again the glaze to fuse. When hard-paste porcelain is broken, it is unfit to distinguish the body from the glaze.

Soft-paste porcelain adds ground glass or frit (material for glass that is not yet fused and vitrified) and is fired to between cone 01 and 1 (1999 to 2109 degrees F). since soft-paste porcelain is fired during lower temperatures, solid does not completely vitrify also remains slightly porous. When soft-paste porcelain is broken, you can distinguish a grainy body lonesome with the glassy layer of glaze.

Bone china has bone ash combined to the kaolin and vitrifies (becomes glass-like) somewhere between cone 2 and cone 5 (2034 to 2205 F). Though not due to hard as becoming porcelain, bone china is more durable than soft-paste porcelain. the bone ash greatly increases the translucence of the porcelain.

Finally, go to a concrete grub and look at their 'porcelain' tiles. If we turn them over, you will look at base clay ranging from burning to brown to gray. its definition of 'porcelain' in the tile industry has hollowness to do veil the terra-cotta blurb or level of firing. Rather, tile manufacturers define considering 'porcelain' any flag fired to the concurrent where it absorbs less than 3% moisture.See More :
