By specifically combining and processing the right components we develop ceramic pigment pastes with unique properties and benefits to the customer. The components are subdivided into three main groups.
1. Glass flux or frit
is most finely ground special-purpose glass. The glass flux is not only the bonding agent of the substrate, such as glass, it also defines the temperature range and gives the colour its chemical and mechanical resistance.
2. Stains and pigments
are coloured metal oxides. The coloured pigments define the shade and determine opacity and transparency.
3. Media
are oily or water-soluble fluids that are used to produce pigment pastes based on dry colour. The use of different media affects the drying process and determines the application (e.g. silk-screen printing, roller coating, spray coating,…).
For the production of our ceramic colours we primarily use natural raw materials and within a certain range of tolerance we apply batch processing. Using different colour batches might result in slight colour shade deviations. To avoid these deviations we offer appropriate batch sizes for larger projects.
We always recommend to fully test the actual-size original glass under production conditions. Modifying individual process parameters (e.g. thickness, drying, furnace practice, furnace positioning, furnace occupancy, furnace atmosphere,...) can considerably affect glazing, opacity and shade.
It is not recommended to expose the ceramic-colored side of the enamelled glass directly to the weather. Depending on the atmosphere the surface can be considerably damaged because of chemical reactions.
