Our products are made with the greatest respect for the natural clay.

The clay is carefully selected and prepared in a grinder where it is made into a paste. As part of this preparation, water is thoroughly mixed into the clay to form a homogenous substance that is easy to work with. The specific qualities of the tiles as well as the colours depend for the most part on the type of clay that has been dug. Colour is determined by iron oxide and lime content. After going through the grinder, the earth is moulded into blocks of clay.

Unlike most tiles made today, which are rolled out, smoothed and die cut, Courboissy tiles are hand-cut into slabs and individually pressed into tommette tile moulds, dried and fired. Using clay with colour variations that shows different veins of colour and the traditional pressing method make these tiles rare, authentic pieces very similar to the 15th and 16th century tiles they resemble.

Our kilns are gas-fired as this fuel guarantees even heat distribution while at the same time allowing the temperature variations that are necessary to achieve the variety of colours found in our tiles. The kiln is heated for three days and two nights to reach a temperature of roughly 1150°C (2100°F). Depending on the ventilation and the intensity of the firing, the tiles will change in colour from the brick red of iron oxide to golden brown and ochre colours. It takes a week for the kiln to cool down and as much time to unload it. Once that is finished, every tile is unique, with texture and colour that differ from one to another.
