Tonala Glass Blowers

I used to have my favorite, but he is gone. Does anyone know of a place that lets you watch the glass work being done?
TIA

I first saw the glass blowers on a tour with Charter Tours 8 or 9 years ago. I went back to the location several times over the ensuing years. About 12 to 18 months ago, I went back and the place was gone. So, I dropped in to see Rosie at Charter and she told me that the man who owned the business died and they closed it. I have heard since that the equipment and a number of the employees wound up with a new owner in El Salto but I have never found out where.
