STAINS FOR
CERAMICS GLAZED
 |
The stains’ stability mainly depends on the composition of the glazes. A high content of ZnO has a positive bearing on the development of spinel brown shades, but not on shades of pink. To obtain a brilliant gloss in the pink shades’ sphene structure, glazes containing CaO are used. Moreover, the stability may be inferior in high viscosity low flux glazes; adding ZrSiO4 to the glazes with a zirconium base increases the stability of the stains.

TINTOMETER
STAINS |
The use of the tintometer calls for a carefully selected range of stain that
match specific characteristics.

STAINS FOR
SANITARY CERAMICS |
The stains for sanitary ceramics must fulfill specific technical requirements: the granulometric uniformity of the stain particles is fundamental to ensure the stability and quality of the color; specific monitoring during the production phase assure our products excellent dispersability in the products to which they are added. Fire tests with particularly long cycles and at particularly high temperatures are carried out in order to guarantee the stability of the stain. Refiring is then carried out to verify the stability of the tested dye. Here, also, a variation in color must not exceed the unit N.B.S. compared with the findings of the first firing. We can therefore guarantee high performance from all our stains.

BODY STAINS |
The series of body stains is characterized by its colorimetric yield, homogenous consistency, and compatibility with all types of body without altering the shrink ratio of the body itself. The production criteria adopted for the glazes in this series have been chosen so that the pigments have a negligibile % of salts and have been refined so as to attain a high quality-price ratio. The result is a final product for our clients that couples high aesthetic value with affordability.
COLORCER® S stains can generally be mixed with each other in all percentages, except for the pinks and those containing Manganese.

ENAMEL
COLORS |
The stains in this range must fulfill specific requirements relating to the vitreous frit used. It is of utmost importance to choose the correct frit in accordance with the pigment’s crystalline structure, particularly for the structures of Cd/Se stains which require transparent frits for the color to develop and intensify. As it is impossible to adequately describe all the frits, we advise the user to trial test the stains in their own environment, paying special attention to the type of opacifier used and initially comparing the different frits utilized. |
