What is Starphire (ultra-clear) glass?

TRENTON, N.J. - June 18, 2014 - PRLog -- Starphire glass is an ultra clear glass that contains as little as 10% of the iron that is found in regular glass.  This allows it to transmit 91% of light, compared to 83% for regular glass.  This helps to minimize the "greening" effect typically found in thick glass panels of glass.
Starphire provides formative advantages in comparison to standard float glass. Particularly, it is characterized by a higher transparency and a more neutral color, making glass ideal where high visibility and clarity are required.

Generally, the cost is anywhere from 15-25% higher than regular tempered glass.  It is generally recommended to upgrade to starphire glass when the customer wants to showcase the shower's interior such as tile work, fixtures, etc.  In the picture you can see the difference between the ultra clear and standard glass.

The estimators at AMG Shower Doors http://www.amgshowerdoors.com believe that upgrading to Ultra clear Starphire glass is totally worth the extra money.  With all the money you spend picking the perfect tile and fixtures for your shower, you don't want to hide this with regular (green) glass in front of it.  Starphire has no tint so it shows the true color of the tile.  In some cases, it will actually make the glass look invisible.
