The glass is first cleaned, in order to rid it of any impurities remaining after machining. The pigments are then deposited on the glass, suspended in a volatile oil.

The first task for Guillaume Bottazzi consists of translating his sketches into full-size drawings before transposing them onto the glass.

It is when the glass is tempered that the fusion with the enamels takes place.
 
Tempering consists of bringing the glass to a high temperature by passing it through a furnace, until it reaches a temperature close to its softening point: between 550 and 700° C, depending on its composition. The surface of the glass is then rapidly cooled by immersing it in a low temperature bath.
 

Once tempered, the glass is usually laminated.

Unlike print on glass, enamels are extremely durable and are highly resistant to UV-ray, scratching and chemical agents.
