See the ancient art of glass blowing practiced much as it has been since 2000 BC. This factory primarily uses recycled glass, so visits are a lesson in ecology as well as artistry. Formal tours are available – call for times – but artisans often give private demonstrations as well. Visitors are sometimes even allowed to try to make a piece. Custom orders for pitchers, vases and other items can be placed several days in advance. A nice selection of items is available for sale.
