The selection of raw materials

The first step is to select the raw materials that will be used to create the colors. Cristallerie Saint-Paul uses mineral powders of natural origin, such as iron oxide, sand or copper carbonate. Each mineral powder has a specific color, which is used to create the different shades of color.

Preparation of mineral powders

The mineral powders are then mixed with binders, such as linseed oil or turpentine, to form a paste. This paste is then cooled and ground in a mortar to obtain a fine and homogeneous powder. The mineral powders are then sifted to eliminate any impurities.

The creation of the colors

The mineral powders are mixed again to create the different shades of color. The artisans at Cristallerie Saint-Paul use precise proportions to obtain the desired color. The colors may vary during the firing process. The temperature of the kilns and the duration of the firing (studied and chosen beforehand) affect the color tones. The colors are then tested on ceramic or crystal samples to verify their rendering.

The application of colors on objects

The colors are then applied to the surface of the ceramic or integrated into the crystal of the jewelry. The ceramic or jewelry is then fired in a high temperature oven to fix the color. The firing temperature varies depending on the color and the material used.

The process of making the colors for the ceramics and jewelry of Cristallerie Saint-Paul is an artisanal process that requires great expertise and special know-how. Each color is unique and requires special attention to obtain an optimal result. Cristallerie Saint-Paul's colors are appreciated worldwide for their quality and beauty.
