Every visitor who approaches this ancient art of glass manufacturing is struck by the professionalism of Vetrate Artistiche Grassi and their passion for the craft. 

The master craftsmen working at the company's workshops model the glass with the same love and enthusiasm they have always had, proud of the work they perform and the great results obtained by the company. The glass manufacturing technique that each visitor can closely admire is that typical of the ancient French glass masters.

The process begins with the study of the project, monitored in every little detail. It starts from a scale drawing made by a specialised designer, which is then transferred to then full-scale design and, in collaboration with the customer, passes to the choice of colours for the glass and of the technical cuts that compose the final stained glass window.

The top-quality coloured glass is cut by hand, joined with lead and soldered with tin. Any painting works which may be included are realised in vetrifiable grisaille fired at high temperature to obtain an unlimited life-span, respecting the ancient technique of the French glass masters.
