Definitions

  • This invention concerns a ceramic body, and also a method of making a ceramic article.
  • the appearance of bone china is generally considered to be aesthetically pleasing. However, significant costs are involved in producing bone china due to the cost of the bone, and also the fact that it is generally not possible to produce articles by a single firing and certainly a single fast firing.
  • the aesthetic appearance of porcelain is often, and particularly in the U.K., not considered as pleasing, particularly as white porcelain tends to have a slight blue-grey tinge, as opposed to the slight red-yellow tinge of white bone china.
  • a ceramic body including zirconium silicate.
  • the body preferably comprises less than 20% zirconium silicate, and desirably 5-15% zirconium silicate.
  • the zirconium silicate preferably has a low total iron, manganese and titanium content, and desirably less than 0.4% iron, less than 0.05% titanium, and/or less than 0.01% manganese.
  • the zirconium silicate preferably has a small particle size, and the mean particle size is preferably in the range 1 to 5 microns.
  • a suitable form of zirconium silicate would be Zircosil 1 (Cookson).
  • the body preferably comprises 30-50% clay.
  • the clay preferably has a low combined iron, manganese and titanium content, and desirably less than 0.5% iron, less than 0.1% titanium, and/or less than 0.01% manganese.
  • the body preferably comprises 10-30% flux.
  • the flux preferably has a low combined iron, manganese and titanium content, and desirably less than 0.1% iron, less than 0.1% titanium, and/or less than 0.01% manganese
  • the body may also comprise a high temperature flux, such as talc.
  • the body preferably comprises 15-35% silica, which desirably has a low combined iron, manganese and titanium content, and desirably less than 0.05% iron, less than 0.1% titanium, and/or less than 0.01% manganese
  • the body may contain a plasticiser, which may be bentonite.
  • the body may contain a colour stain, which may be a cobalt stain.
  • the invention also provides a method of making a ceramic article, the method comprising shaping a piece of clay with a body according to any of the preceding eight paragraphs, applying a glaze to the shaped clay, and subsequently firing the shaped clay.
  • the shaped clay is preferably only fired once, and desirably in a fast fire schedule.
  • the peak firing temperature is preferably between 1150 and 1225°C.
  • the glaze is preferably unleaded, and desirably substantially transparent.
  • a clay body according to the present invention was made with the following components:-
  • the SSP China Clay (Special Standard Porcelain) has a low iron content of 0.39%, and also a low manganese and titanium content. This clay is very white in colour.
  • the talc acts as an auxiliary flux and reduces the maturing temperature of the body.
  • the sand also has a low combined iron, manganese and titanium content.
  • the zirconium silicate has a low combined iron, manganese and titanium content, with 0.25-0.40% iron, 0.02-0.05% titanium, and only a trace of manganese.
  • the zirconium silicate also has a small mean particle size, within the range 1 to 5 microns. This latter feature provides for a high amount of reaction, as well as more scatter of particles, thereby increasing the colour properties provided by this white component.
  • the bentonite acts as a plasticiser and can be either Vee Gum or bentonite L.
  • the cobalt stain provides a very slight blue tint to the body.
  • the clay is mixed with water by blunging to give subsequent workability. This blunging could take place for example at high shear for around thirty minutes, or at low speed for around one to two and a half hours. Once sufficient workability has been obtained, the other ingredients are mixed in. The mixture is then sieved and passed over magnets to remove magnetic material such as metallic iron. The material is then dewatered in a filter press.
  • the dewatered material is de-aired in a pug mill and it is important to ensure that the pugging is carried out efficiently to exclude all air.
  • the material is extruded to form a pug which is cut to an appropriate size and placed into a mould to make for example a mug.
  • a roller head is applied to shape the pug.
  • a handle is made by slip casting and adhered to the shaped body with slip.
  • the shaped item is then dried.
  • a lead-free transparent glaze was formed in a conventional manner from the following components:-
  • This glaze was applied to the shaped clay by dipping, followed by subsequent drying.
  • the glazed article was fired in a single fast fire schedule. In this schedule the article is brought up to a peak firing temperature of 1200°C in one hundred and twenty minutes, and held at this peak temperature for a further thirty minutes. Rapid cooling then took place over ninety minutes.
  • the mug formed by this method had a pleasing white appearance, generally similar to that provided by bone china.
  • This method and body permitted only a single fast firing to be used.
  • the zirconium silicate in combination with a low combined iron, manganese and titanium content, a good white body colour is obtained which can be clearly seen by virtue of the transparent glaze.
  • the high refractory index of zirconium silicate helps in providing the strong white colour.
  • This material also acts as a refractory component to prevent sagging of the product.
  • the fired article has a coefficient of water absorption of no more than 0.5%.
  • the body and method according to the present invention permit relatively thin walled articles to be made.
  • a high temperature flux may not be necessary.
  • silicas could be used, and in different proportions.
  • the zirconium silicate could be of a different type and again could be provided in different proportions.
  • Different plasticisers could be used, and a plasticiser may not always be required.
  • a wide range of different glazes could be used, as long as appropriate transparency is achieved so as not to affect the colour of the underlying body. Appropriate glazes can obviously be chosen to correspond to the specific bodies to have the required relative thermal expansions.
  • a wide range of articles could be made using a body and method according to the present invention. Different firing conditions can be used. For the above described body the peak firing temperature can range from 1150 to 1225 °C with a corresponding Bullers ring range of 27-34 pips.
