Starfire glass?

I guess you don't believe in glass showers either or car and home windows? It takes a lot to cause thick tempered glass to shatter even by chipping the edge, it's not as easy as you might think. You can chip the edge of 10mm tempered glass it won't shatter, plus the chip won't spread to a crack as the crystal structure is realigned into a compression stress instead of tension. Plus if safety is a concern tempered it way safer. If you kid managed to blow out your tank at least a huge sharp piece of glass won't take his head off, with tempered worst case they get wet. Smart design doesn't mean cheap.
