I've been retired for too long to know where to shop for stained glass supplies any more. Chris P. makes a good point about the unwisdom of using leaded glass for clarinet-sanding. Good question to ask the supplier -- but, in general, people who etch decorative glass for table-wear, lamps and windows don't use lead crystal. In my whole career (lamps, windows, other decorative things and restoration work), I never used lead crystal (for anything) or met anybody who used lead crystal. Art-glass is soda-lime glass.
When stained glass artists use the term, "leaded glass," they're almost always talking about one of two processes. One is the process of putting pieces of glass together into mosaic pictures, by fitting the cut-out pieces of glass into strips of metal came. (Came = strip of flexible metal, such as lead or zinc, with slots down the edges.) The edge of the piece of glass fits into a slot in the edge of the came. Then the artist solders the pieces of came together and putties the window to hold the glass in place. The other process, for smaller, more detailed artwork that doesn't need to take a lot of stress, involves wrapping the edge of each piece of glass in copper foil, laying the foiled glass pieces out on the paper pattern, then decoratively soldering all those edges with either lead solder or lead-free solder.
Because most stained glass studios do make use of lead and/or other stuff you don't want smeared onto your reed (ground glass, for instance!), please do wash the glass thoroughly before using it as a reed-scraper.
