Follow this simple, 6-step, process to avoid a measuring charge

  • Determine the glass thickness eg 1/4” or 3/8”
  • Decide on the glass color eg clear, gray or bronze
  • Choose between annealed or tempered
  • Measure the dimensions: width * length
  • Decide on the  edgework: seamed or polished
  • Describe the corners: square, radius or clipped

Step 1: Determine the Glass Thickness

glass thickness

Choosing glass thickness is simple because the best choice for almost all protective tops is 1/4” thick glass.  The only exception is the case of large conference tables in which holes are required for electrical wiring.  In some large tabletops, 3/8″ glass is recommended for extra strength (consult your glass professional for advice).

Step 2: Choose the Color of your Glass

Next – decide on the color of the glass – probably 95% of our customers choose the most affordable option which is clear glass (clear glass actually has a greenish tinge owing to it’s iron contain – It is important to appreciate that the shade of green depends on the amount of glass you are looking through.- so the edge of a long glass table top will look almost black.

There are other color options for protective 1/4” glass, so come into our studio and look at samples if you feel you might prefer gray (commonly used with stereo or HiFi equipment, bronze, black – sometimes used to disguise damage or expensive low-iron or starphire glass.

Step 3: Annealed or Tempered Glass?

Step 3 is to decide whether you want annealed or tempered glass.   Most customers choose the more affordable annealed glass for protective tops because the danger of breakage is low.

Tempered glass (above) is five times more impact-resistant, will withstand heat and is much safer when broken (it shatters into  harmless popcorn fragments.).

Regular annealed glass (above), in contrast, is potentially more dangerous as it breaks into sharp jagged shards.

Insider safety tip

Building safety codes do not mandate tempered glass for tabletops so the choice is up to you – safety-conscious customers (maybe if you have teenagers in the house or if you insist on placing very hot saucepans on the glass) – may prefer to play it safe with tempered glass.

Step 4: How to Measure a Rectangular Tabletop

The next and most crucial step is to carefully measure the width and length of the table – if you are not already familiar with a tape measure – notice that an inch is divided into 16ths. Measure to the nearest 1/16′ – and for more confidence use a 2nd tape measure to double-check your readings – Remember – if your table is too big, we cannot grind off 1/8” the correct the error.

For the best results – study the edge profile of your table to see if it is rounded or beveled.  Measure the dimensions of the FLAT part of the tabletop – we do not recommend letting the glass overhang the table edge.

Step 5: Decide on the Edgework - Seamed or Polished

Economical “seamed” glass (left) is OK for work tables but a perfect flat-polished edge is the best choice for furniture.

Step 6: Specify the Corners - Square, Radius or Clipped

Finally, Check the table corners: most rectangular tops have square corners and we round them slightly to remove the sharp point. Some tops need rounded corners – these are specified by the radius of a circle that defines the corner. In a similar way, clipped corners are defined by the length of the side of the square that defines the corner.  If the corners are irregular or you having difficulties measuring – just make a tracing of the corner and bring it into our shop.

Cracked Glass Tabletops

Cracked or crackle glass, also known as shattered glass, is made from three pieces of tempered (heat-strengthened) glass laminated together. The middle piece is shattered into thousands of popcorn-like pieces to create a sparkling, crystal-like effect. Despite its appearance, it is perfectly safe and durable because the shattered piece is sandwiched between two high strength pieces of glass.
