Ceramic Roof Tile Engobes

We supplies made-to-order engobes for roof tiles. They are available in liquid (slurry) or powder form. Engobes are a mixture of minerals applied to a roof tile before glazing for decoration and to make the tile more durable to weathering. A wide variety of colours with either matt or brilliant finishes are available enabling consumers to make an original feature of their roof tiles for example for new buildings, or even to imitate the patterns on old weathered roof tiles which usually take years to develop.

The main property of an engobe is its colour and the challenge is to ensure that the colour maintains stability through every production batch. We ensures this by keeping the very first production batch of each product as a control against which all future batches are compared. our quality control specialists consider not only the colour, but also other key parameters such as the aspect (soft, rough, brilliant, matt); the viscosity of liquid products and the lifetime of the engobe, which is typically one year. Bacteria growth pose a serious threat to the quality of the engobes and its viscosity, we controls these through biocides and others high grade chemical products.

Engobes for roof tiles are, by definition, tailored solutions. In accordance with customer requirements we have the resources to provide both very large and small volumes. In addition, the geographic area, the properties of the tile's clay, the characteristics of the engobe application, the firing temperature etc. must all be accounted for when imitating a particular slate grade for instance. Six Star Colors has over 100 references for engobes, and each one has been designed for a specific customer. Some examples of  Six Star references include:

Slatey grade, a shiny dark engobe that gives a very stable slate effect

Flamed brown grades, applied as a fog for rustic roofs

Powders for applications with relief, for imitation of lichens and weathering patterns

A very high grade engobe with a long lifetime that ensures against cracks and spots
