Tolerances & Lead times:

Cutting glass is a completely different process than cutting wood or other materials.  Because of the fundamental nature of glass, the industry allows relatively generous tolerances.  
A piece of glass may be cut (larger or smaller) within the Standard Industry Tolerance Chart below.

TEMPERED GLASS UP TO ¼" THICK:
Tolerance—(+/- 1/16")
Lead time-----2 weeks as long as order is received by Tuesday
BEVELED GLASS UP TO ¼" THICK:
Tolerance—(+/- 1/16") 
Lead time-----2-4 weeks (special patterns could take an extra week)
GLASS, MIRROR, OR PLASTIC 1/8" THICK :
Tolerance—(+/- 1/32")

GLASS, MIRROR, OR PLASTIC 3/8" THICK:

Glass Defects:

All glass may contain flaws or blemishes which can be visible to the naked eye.  Even the highest quality raw materials contain minor flaws.  The federal government mandates that not defects should not be visible in the glass when it is viewed horizontally or vertically  from 11 feet away, under normal lighting.

Consumer Guidelines for Handling Glass:

Glass is a useful & beautiful product.  However, glass can be easily damaged if not handled properly.  We have carefully inspected & packaged your merchandise prior to shipping.
  
Please read the following before un-packaging your Berkshire Glassworks purchase:

- Be sure to have enough people to safely handle your package.  Glass may be heavier than you expect.

- Use extreme care when using hammers or crowbars to remove from crate or other shipping container.

- Remove all staples or nails before unpacking glass.  Failure to do so may result in damage to your glass.  Never slide glass over staples or nails. 

- Never set you glass on concrete, metal, or tile floors without padding.  This could chip or scratch your glass.

- Wear gloves especially if  handling larger, heavier pieces of glass.
