While traveling Wyoming, I briefly saw a glass bottle wall. I came home and started saving bottles and have accumulated quite a collection that I would like to use to enclose a six by eight California slider. I've built and rebuilt numerous properties and I am comfortable ripping things away to add something lovely.
I would like to know, for insulation purposes, which direction the necks vs. the bottom of the bottle should face? I relish the idea of the bottom of the bottle being a piece of art work inside the existing structure but if the neck/opening should be inside vs. outside please advise and I will adjust my vision.
