Let me tell you about the unique and deep loathing I have towards glass.

It isn’t just the finished product, you understand. I hate silica too, as well as soda ash and limestone. I also hate glass blowers, kilns, and all those ornamental baubles pulled from the molten stuff into the shape of a swan. As for double glazing… don’t get me started on the science of double glazing unless it involves putting a brick through it.
