The Mechelen glazier guild model book contains designs for stained glass windows, an essential part of the entrance examination for those aspiring to be called a ‘master glazier’ or ‘master glassmaker’. This was part of a years-long training. The final test was the completion of the master’s piece, a mandatory work that the candidate had to present to the guild's board. Only after approval of this piece were they recognised as a master in the trade and allowed to practise the profession.
Many of the glazier guild documents were lost after its abolition during the French period (1797). This 17th-century model book has been preserved by chance. The unique book – the only other similar copy within our country can be found in Bruges – bears witness to the operation of the guild and the approach to the master’s piece in particular. The wide variety of geometric patterns indicates a broad range of choices for tackling the test. It is noteworthy that the model book also includes a pattern for the master’s piece in Antwerp. The Mechelen model book has been granted the protected status of a Flemish masterpiece thanks to its its great historical value and rarity.
