I would actually be interested to know this too... Also, has anyone done a natural gas firepit with "fire ice" (basically like a crushed glass) and a natural gas fire ring... Here is an link to a site with something like what I am talking about (second link is to a before/after picture, just click after to see it). http://www.fireonice.com http://www.fireonice.com/images/photogallery/5.swf
