with .1 raised or separate chapter ring applied to a 

 brass or copper plate, such as a copper-pl.nr 1 

 and 'jilt with baroque motifs, or upon a smooth brass 

 plate with spandrels of repousse work usually of silver 

 in relief and attached. The engraving of the chapter 

 rings was excellent. The hands were well executed 

 in steel or perforated bronze, and occasionally of 

 repousse copper; gilt was applied to the hands made 

 of forged steel. 



In the course of time, Bertolla"s home workshop 

 passed from one generation to another within the 

 family. Inevitably, it underwent many modifica- 

 tions until the only original part of the building thai 

 remained intact from Bertolla's time was his clock- 

 shop, 



Within the last few years, the workshop room was 

 acquired complete with contents from Bertolla's 



descendants, and installed in the Museo Nazionale 

 della Scienza e della Tccnica in Milan as an exhibit 

 of a typical 18th-century clockmaker's shop. 1 he 

 original workshop was dismantled in Mocenigo di 

 Rumo and completely rebuilt in the museum, in- 

 cluding the walls, ceiling ,nu\ floor. The paneling and 

 woodwork of the walls and ceiling, which havi 

 preserved intact, are hand-cut fir. with columns, trim 

 and moldings carved by hand. A small painting is 

 featured in the center of the coffered ceiling. The 

 original shop benches and chests of drawers are set 

 around the reconstructed shop and Bertolla's tools 

 and equipment laid out as they had been originally. 

 Other clockmaker's tools and equipment in the 

 museum's collection are also displayed. Approxi- 

 mately 4u percent of the tools are the original items
