Drilling Tanks

They are suppose to be. It is the convention at the kilns to label all glass that is tempered. When the glass is distributed, the buyers need to be able to distinguish what has been tempered and what hasn't. In addition to the kilns' logo and "tempered glass" label, it has a warning not to drill or cut the glass.

That isn't a guarantee that all tempered glass is going to be labeled. I have never seen any first hand that wasn't labeled.
 
actually i believe that some tempered glass can be noticed. it depends on thickness grade etc. also hey mainly use australian glass from pilkington/viridian to temper because it is the highest qualtiy glass. it has the least air bubbles in it which cause panels to explode when being tempered, which the shrapnel then causes the other panels to explode.
 
I was directed to this thread because im trying to identify if my glass is tempered.

Seems like there are some glass pro's on this thread so hopefully someone can help me identify my glass type.

I got the tank used for a smokin deal so i have no idea where it came from. there are no brands or any other kind of marks on the glass that would help me identify it

the glass is about .5 inch thick and has some light scratches on the surface.

and it sounds like it doesnt make much difference but it doesnt have any swirls through polarized glasses.
 
Polarized glasses only works with automotive glass because it is so frequently UV treated. And it is always tempered (except windshields or laminated glass). Anyway, I tried polarized glasses on several pieces of tempered glass and none showed any signs seen in automotive glass.

The scratches are your best sign that it isn't tempered. The surface of tempered glass is in compression and has the tendency to close the gaps in scratches (sort of like self healing).
 
My 2p worth:

You can do without a jig by starting off at an angle - about 5 degrees is fine. Once you've made some headway you can change to perpendicular. I use a syringe to drip water on the region occasionally and use the drill on the slowest speed possible. No pressure on the bit whatsoever, really just letting it polish it's way through rather than grinding. Keep checking the bit and the glass with the back of your hand to ensure there's no heat building up.

Once you've first broken through use even less pressure until you're done :)

Very very boring!
 
what is the purpose of the holes. i mean not to sound dumb but i dont know. i think it has benefits for filtering purpose but again i dont know. should these be on a 55 gal cichlids tank? could you explain this so i can decide should this be best for my tank

It's so you can use a wet/dry filter. There are other ways to do it (overflows). This just cleans up the tank. It is also for other custom work such as adding an external pump to a glass sump.
