What thickness should a glass table be?

I want to make my own dining table. I'm planning to buy a glass table top, but I need to know if a glass of 1/4" will be fine for that.

Condition: Brand new item in box

Shape: Rectangle

Available: Sizes36x60

Glass Type: Clear Glass

Edge Work: Beveled Polish

Corner Finish: Eased

Strength: Tempered

Also I think using a Nano470 Construction Glass Glue for adhering to the base would be fine.

Should I buy a glass with a greater thickness?

Another thing I am asking is how can I illuminate the glass with LED. I see something in this site at the bottom of the page:

Would this work?
