glass experts please chime in

OK, the viewing panel on the tank I'll make this winter is 76"x29". I plan on using tempered, low iron, 3/4" glass. Awhile ago, I learned that panel will need to positioned correctly, as it will have a face that needs to face outward. I forget wether it is due to being temperted, or due to being low iron.

I seem to remember that a blacklight helps determine how to position the glass?

Are there different types of tempered glass?

If so, what kind of tempered glass do I want for a tank?

Low Iron glass does not have a specific side that needs to be out or in, you might be mistaking this for Low "E" glass which has a coating on a particular side (You Don't Want to use Low "E")
Low Iron is what you want to use, it's closer to optically clear with no green tint as normal glass does.
Tempering is just heating and quenching the glass to make it stronger. During the tempering process the glass will develope strain marks do to unevan heating and cooling which you can see with polorized glasses.
I do not temper the glass on my tanks. "thicker is better"
Hope this helps.

Thanks glassguy.

Is there a table or chart for glass thickness on a tank? I planned on 3/4" tempered because it seemed substantial enough. Really just a guess. I will use a euro-brace. What would you reccomend for this tank?

What is the final dimension of your tank?

Hai salty joe, in here if you use the tempered glass will be not to good stick together. because the tempered have minimum pore, the proced heating the glass. i have exp after you fill it with water the silicone will be off.

What do you mean by minimum pore? I've owned all glass aquariums with a tempered bottom. I never heard of tempered glass having different adhesion properties than regular glass.
