Abstract
The paper presents the study on the identification of patterns of coloring of a basic glass matrix and enamel coatings based on it in the system R2O–ВаО–ZnO–Al2O3–В2О3–TiO2–SiO2 by a number of ionic dyes. Regardless of the dye content, ionic dyes give the same color tone to both glasses and coatings based on these glasses as follows: CuO (1.0–3.0 wt.%) =489–494 nm (blue-green), Fe2O3 (0.5–2.0 wt.%) =575–585 nm (yellow), K2Cr2O7 (0.5–2.0 wt.%) =570–576 nm (yellow-green), CoO (0.5–1.0 wt.%) =441–463 nm (blue-violet), and NiO (0.5–1.0 wt.%) glass=559'–571' nm, coatings=598–629 nm (brown). It is shown that according to the degree of color intensity of glasses and coatings based on them, the dyes are arranged in the following sequence: CoO>NiO>CuO>K2Cr2O7>Fe2O3.. The research was conducted using a special computer program COLOR GLASS. The established patterns are used in the development of lead-free glass enamels for jewelry and decorative products.
