Visit to an Inlay School/Shop in Florence

by johndonivan on September 29, 2009

 Walking down the street in Florence, Italy a couple of weeks ago, Jo-Ann poked her head into a doorway and came and got us.  “Hey, let’s check this out, she says…..”  Turns out it was an old-school inlay shop – the sort that makes pictures and table tops and the like.  VERY expensive, I’m afraid…  I’ll mostly just post the pics we shot..                                     

First the picture is drawn like a cartoon – hard black lines with white spaces.  Then each element is carefull cut out of paper and used as a template or pattern on the stone slabs.  Each piece is cut with the saw, and then assembly is with a beeswax mixture.  Once we told the owner we were jewelers and I talked to him about my own stone experience, he opened his doors wide for us…  Nice man, cool shop, old school work beautifully done.
