In researching 'Nouveau' and 'Ilanit' glass I found this which could relate to this post.
Re Nekkers in Jerusalem, from Frommers travel guide.
'It was this store, near the Mirrer Yeshiva on the northern fringe of Mea Shearim, that revived the ancient glassblowing traditions that began in this part of the world more than 2,000 years ago. The Nekker family arrived in Jerusalem from Baghdad in the early 1950s and quickly set up a small glass factory employing both Arab and Jewish glassblowers. Slowly the factory began to experiment with designs and techniques from ancient times, and has even developed ways to reproduce soft, ancient patinas in a variety of colors. At Nekker's tiny workshop, you are invited to watch the glassblowers at work. Yehuda Nekker, the patriarch and chief designer, virtually dreams in glass. The stock is on sale for a fraction of what it costs in retail shops. A special line of museum-style reproductions is higher in price. The Nekker staff will pack your purchases securely for travel.'
The e-mail link does not work, they don't have a website, no pics and so
I'll write by snail mail for more info.
