Unfortunately, there is no definitive answer for the length of time Biagio Barzotti took to produce his micro-mosaic “Paizza S. Pietro nel momento della Benedizone Papale.”   According to a late 19th century article in Ballan’s Pictorial, there is no date listed for the publication, v.11, p. 83, the usual time for micro-mosaics produced at the Vatican Mosaic Factory is between 12 to 20 years.

I also consulted the following works:

Savelli, Collezione.  Mosaici minuti romani.  Rome: Gangemi Editore,  2004.  Print.

Whitehouse, DavidThe Corning Museum of Glass: a decade of glass collecting, 1990-1999.  Corning, NY:  Corning Museum of Glass, 2000. Print.

 

According to the below journal article the usual time for micromosaics produced at the Vatican Mosaic Factory was 12-20 years.
