Comparing Amber Pyrex & Amber Visions

In the right light, the colour difference between the two materials is quite obvious.  Under most conditions however, they do seem relatively similar, and the brand name will always confirm whether it is Pyrex or Visions.  If the product is not marked Vision or Visions, then it is not glass-ceramic stove-top ware.  Items with a "not for broiler or stovetop" warning are made of Pyrex.
