Body Decoration

For those customers requiring stains for colored bodies, engobes and relief work, Sukaso has a wide spectrum of stable, consistent pigments, which are manufactured under strict processing conditions, to meet the technological and application needs of the market.

Colored Bodies & Body Stains

Colored  clays, either natural or colored by the presence of ceramic body stains are used for figurines, tableware, tiles etc. Here fine grinding of raw material is important if the color is to be uniform.

Owing to the cost of ceramic colorants, it is usual to use only small quantities (1 - 5%) when coloring a body throughout. Colorant is mixed in the body by wet grinding. Very careful milling, measuring and blending are necessary for best results. The firing temperature will vary and depend on the composition of the body.

Colored bodies may be left unglazed, or covered with a colorless glaze. Interesting effects are also achieved by using a slightly opacified white or light colored glaze.


Colored or stained body material may be used to decorate the surface of a piece.  For e.g., thick ware may be made from a body whose color is undesirable, and then covered with an engobe, or body slip of higher and good color.

The composition of the engobe will be adjusted according to the body it has to cover. It is prepared by fine grinding the colorant with non- plastic material. It is applied on the body by dipping, spraying or brushing.

Relief Work & Inlaying

Decoration methods like scratching, modeling and piercing is possible on hard bodies to give special effects.

Glaze Decoration

These user-friendly, environmentally safe colors have been formulated for use as Onglaze, Inglaze or Underglaze Deco systems. Their fluxing characteristics render them suitable for use on a variety of substrate types, including Porcelain, Bone China, Vitreous China, Stoneware and Earthenware. They are also capable of being fired under both fast firing and conventional longer firing cycles.


The ceramic agents are processed into the form of paint or ink with filters, carriers, oils and the like, and can then be applied to the ware by spraying , brushing, dusting, decals, stamping, transfer or screen printing. The glaze is then applied over the decoration and then fired to make the decoration permanent.


The coloring agents mixed with low melting glassy flux are applied to ware that has already received its gloss firing and are fixed to it by further firing at lower temperature. It can be applied in all different ways followed for under glaze decoration.


The ware is glazed and when this is dry but not fired, the decoration is hand painted on it. A characteristic soft effect is produced.

Methods of application of the glaze colored designs

Due to the diversity of physical and chemical properties of ceramic colorants together with variety of surfaces and shapes they are used on, a very wide selection of methods of applying the colored designs have come into use.

  • Direct application: Hand painting, spraying, banding and lining, crayoning, ground laying.

  • Semi-direct application: The design is made in permanent form which is used to apply the colorant to the ware by stamping, stenciling, screen printing.

  • Indirect application: The design and colorant are produced on a thin sheet of a paper from which it is transferred to the ware- offset, paper transfers, engraving, lithography, screen printing.

Note: In every method of applying colored design, the physical properties of individual colorant preparation play an important part and will, in general, be different for every one. Thus one will have more tendency to run, settle out, clog up, dust off etc., than another. It is therefore, necessary to get the right knack for every colorant. It is also very important to derive the best sequence for applying a number of colorants to a single piece as the final effect will differ with the order followed.
