Nowadays, glass coatings have a wide range in the industry and have been an important research topic. It is preferred to use glass as a decorative object especially in daily life. In this study, decorative glass coating was tried to be developed with the use of ulexite. The ulexite mineral is a mineral consisting of white round crystalline masses. Test results (visual, hydrophobicity, adhesion tests, etc.) showed that the use of ulexite with additives (potassium dichromate and surfactant) positively affects the coating properties in decorative glass coating production. In the experimental study, Taguchi Method was used as an optimization method and the results were analyzed to improve cost and quality to determine the optimum process parameters. TG-DTA (Thermal Gravimetric Differential Thermal Analysis) and SEM (Scanning Electron Microscope) methods were used to characterize the thermal properties and physical morphological properties of the coatings prepared, respectively. It was observed that the additives added in the coatings prepared did not have a negative effect on the structure of the coating. As a result, the additives used improved the properties of glass coatings and the results showed that additive coatings prepared in various industries can be evaluated.
