prof Posted February 19, 2009 Share Posted February 19, 2009 This is why you don't drill tempered glass. This is also the only way I know to find out for sure if glass is tempered Link to comment Share on other sites More sharing options...

johnoburns Posted February 19, 2009 Share Posted February 19, 2009 I've been curious about this myself and have done some research. It seems that a lot of places that temper glass put a logo on the glass. Also, it seems that if you use a polarized film or sunglasses in daylight you can see a rainbow pattern in the tempered glass. Supposedly you are not supposed to wear sunglasses while driving because of this effect. Something else I have seen people talk about is taking it to a glass shop and they should be able to tell you. I know its a little late to hear this, but perhaps it will help someone in the future. Link to comment Share on other sites More sharing options...
prof Posted February 19, 2009 Author Share Posted February 19, 2009 I have diamond embedded drill bits and cooling oil. I was not surprised to see this one crack. It was just a cheap 10g with thin glass. This is the first tank that I have had fail on me. I will have to try the polarized lens idea. Some manufacturers will labeles their tempered glass but you never know for sure. Most tank bottoms are tempered, which is why I have never drilled the bottom of a tank.

+ACampbell Posted February 19, 2009 Share Posted February 19, 2009 PVC bottom is the way to go. Link to comment Share on other sites More sharing options...
Cool Breeze Posted February 19, 2009 Share Posted February 19, 2009 Go with a wood bottom. Drill bits are cheaper. Link to comment Share on other sites More sharing options...
caferacermike Posted February 19, 2009 Share Posted February 19, 2009 Word is that 2 polarized camera lens filters placed one on top of each other is supposed to help ID tempered glass. I believe that you spin one filter and if it makes a "+" sign then it is tempered. I'll need to do some digging to see if that's for sure. Link to comment Share on other sites More sharing options...
