Spray decorations in porcelain manufacturing

The technique of spray decoration originates from the "modern" production of background decorations or solid colours. A compressor is used to transfer the decorative colour to the body as a fine mist of paint under high pressure using a spray gun. Spray decoration has completely replaced full-body brush decoration in the utility porcelain segment because spraying the decorative colour onto the porcelain is much faster and has fewer sources of error.

The same spraying technique can also be used if the colour is applied to the green or biscuit shards. In this case, however, it is not called spray decoration, but spray glaze.

By constantly rotating the porcelain body on a disc, the fine mist of paint from the spray gun is applied evenly and evenly to the porcelain body. Normally, strong solid colours are sprayed on as a full decoration. In the video above, however, we show you something very unusual. Instead of an evenly covering colour, in this video small mineral "metallica pigments" are sprayed onto the biscuit-hard body using the spray decoration technique. But this is just one of the many details and secrets we use to produce our "reactive porcelain".

The job of a "fondant sprayer" is one of the most unpopular activities in porcelain production. Solvents and the fine gases from chemical ingredients in the porcelain colours simply cannot be healthy. Anyone who has spent several hours at such a spraying station experiences irritation of the eyes and respiratory tract. Although masks are compulsory and most factories only spray in special rooms with appropriate filter and cleaning systems, the skull and crossbones remain on the paint buckets as a warning about the contents. Such spray chambers have hardly changed over the last few decades. Even well-known luxury brands produce their spray decorations using the same technology as shown in our video.

We therefore endeavour to produce solid colours using the dipping process wherever possible and not with a spray gun. Incidentally, the pigments shown in the video are sand-based and contain only natural raw materials and no solvents.

We put a lot of emphasis on this!
