Type of glass for baffles ?

[FullPull]

I've got a 29 Gallon lying around doing nothing and was going to use it for my 55's sump. My question is....What type of glass do you use to make the baffles out of?..Is aquarium glass tempered or hardened?....Just needed to know

How much do they charge to cut glass and do they have a limit as to how small a peice they'll cut for you?

I don't think Home Depot cuts glass anymore.

I had six pieces of glass cut at Lowes and there was no charge to cut it

Thanks guys, it will sure be easier than messing with acrylic. silicone is pretty forgiving as far as time and mistakes goes

I have used 1/8 inch glass from HD. As the water filled from the intake side to the return side, each glass broke. It was not a complete loss, I learned to cut glass with those pieces. I went to a local glass supplier and found that I could get the same size in 1/4 inch at the same price as HD's 1/8 inch. Another lesson, life is full of them.
I have worked with acrylic and prefer to work with glass. I would have made my overflow with glass, if at the time I had the tools to cut holes.
This is a 20 gallon that is under my 55 gallon tank.
