Abstract

The invention provides a method of decorating ceramic ware such as a cup or mug, so as to have one colour inside and another colour outside, with the two colours meeting at the rim. The rim is treated with a medium which repels the glazes so that the colours applied to the inside and outside meet at the rim but do not mix. The medium may applied prior to glazing or after application of the first glaze.

Description

SPECIFICATION Decoration of ceramic ware This invention relates to the decoration of articles of ceramic ware and is particularly concerned with the problem of applying differently coloured glazes to surfaces which meet at the rim of an article; for example the inner and outer surfaces of a holloware article such as a cup or mug or the top and underside of a piece of flatware such as a saucer.
According to the present invention we provide a method of decorating an article of ceramic ware in which differently coloured glazes are applied to respective surfaces which meet at the rim of the article, characterised in that said method includes the step of applying to the rim a continuous band of a medium either: (a) prior to the application of both glazes; or (b) after application of the first glaze and before application of the second glaze; said medium being repellent towards both glazes in case (a) or at least the second glaze in case (b) whereby any glaze deposited on said band is shed by the latter to provide a well defined line or area of demarcation between the two glazed surfaces.
Typically the glazes will be water based and said medium will have water-repellent properties. The medium may be clear or it may itself be coloured and, in the case of a cup or a mug for example, the inner and outer surfaces and the band may all be differently coloured, for instance white, pink and grey respectively.
The glazes and the band may be applied before or after firing of the clayware article.
In one embodiment of the invention involving decoration of a mug, the following procedure is followed. A band of said medium is applied to the rime of the unfired article by means of a commercial paint brush while rotating the mug about its axis. After the band bas been allowed to dry, the mug is immersed into a constant level tank of water based glaze (which may be coloured pink for example) until the glaze rises to the level of the band.
The mug is removed from the tank and allowed to dry. Any glaze that may have overlapped the band during immersion will not adhere and will be shed by the band. The second coloured glaze (e.g. white) can be applied to the inner surface of the mug by inverting the mug over a fountain so as to spray glaze upwardly into the mug. After spraying, the mug is left to drain and dry.
Again any glaze that overlaps the band during spraying or draining will be shed by the band to leave the band unmarred by the applications of glaze. In this way, the band serves to prevent any merging together or intermingling of the two glazes. The mug may thereafter be fired in the usual way.
Although it is preferred to apply the band before both glazes, it is considered to be within the scope of the invention for the band to be applied after the first glaze as been applied and allowed to dry. The subsequent application of the second glaze is then prevented from merging with the first by the band.
A suitable resist material called "topping colour" is used under the Trade Mark "SPEC TRUM" by Harrison Mayer Limited of Meir, Stoke-on-Trent.
