About Granite Kitchen Sinks

The material is not solid granite. It is composed of crushed quartz and an acrylic resin binder. Quartz is the hardest material in granite, typically with a concentration of about 20%. Granite sinks are composed of 80% quartz to create a very hard, tough material that is also called:

  • Composite granite
  • Granite composite
  • Composite
  • Processed granite
  • Brand-specific names such as E-Granite (Elkay) and Silgranit (Blanco)

Note: Keep in mind that the granite composite sink industry does not use strictly uniform production processes, so each brand’s sinks are a little different. Manufacturer’s websites are a helpful place to find the details of how each brand’s composite sinks are made.

Granite Composite Kitchen Sink FAQ

This brief granite sink Q&A addresses additional topics that might be of interest to you.

I read about granite sinks becoming hazy and dull. How can I prevent that?

The cloudiness that can plague granite composite sinks is a result of minerals from hard water and/or salt from softened water clinging to the surface. First, most manufacturers recommend rinsing the sink and wiping it dry after use. This is a theme in sink care now for many types of sink including stainless steel and cast iron.

Secondly, some of the current generation of composite sinks have finishes that more effectively resist the deposits that cloud some sinks. Still, be prepared to give your sink a bit of TLC.

If the sink dulls, can anything be done to remove the cloudiness?

This is covered in more detail in the Composite Granite Sink Care & Maintenance Guide, but yes, you can remove the cloudy haze. White vinegar by itself might work, or a product like Blanco’s Blancoclean Silgranit sink cleaner will do the job. Another good choice is Supreme Surface Scum & Mineral Deposit Remover.

What are the pros and cons of a very dark granite composite sink? What about a light sink?

The concerns are that mineral and salt deposits show up more quickly on a dark surface. Food particles do too. On the plus side, a dark sink hides scratches better than a light sink – though the better composite sinks on the market today offer excellent scratch resistance.

The opposite is true of a lighter sink – hides food particles but shows scratches more readily.
