What is Glass-Source?

Glass-Source is a worldwide search tool for companies in the glass business, including hot, warm, and cold glass studios; manufacturers and distributors of raw materials and finished glass products; and bead shops. We think you will find that our twenty years of experience in the glass industry that supports the development and maintenance of Glass-Source make it the most authoritative business listing on the Internet.

How do we compile the finest database of U.S. and Canadian glass businesses?

Profitable Glass Quarterly uses the most complete and accurate source of business information for sales, marketing, and credit applications. Creating this database requires a full-time staff of employees who update and verify information on a continuous, real-time basis. Even though we use the most reliable sources available, the information does not go into our database of retail storefronts until it’s verified by our telephone research staff. There is simply no better way to ensure the accuracy of our data. Yes, it’s expensive, but we think your satisfaction is well worth the investment.

Then we make phone calls.

By actually calling all of these businesses every year (and more often for larger companies), we can keep up with the tremendous amount of change that occurs. We confirm addresses and phone numbers, weed out companies that have gone out of business, and collect additional information that includes the name of the owner or key executive, number of employees, primary line of business, and more. Our telephone verification process is what sets our database apart from our competitors.

The end result is the best database of stained, leaded, and decorative glass business ever created.

In terms of completeness, accuracy, and depth of information, no other source can compare to our database. Our commitment to quality at every level of the compilation effort guarantees you the best business marketing reach available.
