Hi, I did reply to your same question on BTF. There is not any glass blowing in Lombok to my knowledge. There is a big glass blowing factory in Surabaya on the island of Java (they make lamps etc), and also artistic type glass blowing in Yogyakarta.
There are many handicrafts in Lombok, but it is pretty much traditional handicrafts for the region. Whole villages will specialise in a particular handicraft.
For cut glass for windows and mirrors there are several stores in the Chakra area. I don't have any specific addresses.
