Section 7 - Clear & Colored Glass   (Page 1)

The purpose of this section is to provide examples of clear and colored glass buttons as defined in the NBS Classification Guide1 (Blue Book) including one or more examples of each type in the listings and an example that covers each term in the definitions. Passing your mouse over the button image will turn the button over so both sides may be seen. In some cases, more than one example of a type is shown. One reason for duplication is to demonstrate that one glass button frequently fits into multiple class/subclass categories. No attempt is made to show all combinations of basic colors and other characteristics (DF, OME, Construction, etc.) since there are thousands of such combinations. A separate color primer page is included to help the novice better understand basic colors for competition. The "Color Primer" page link above will take you there. A link to a printable primer worksheet is at the bottom of this page.  Scanning and photographing buttons have distinct limitations in the areas of perspective, color, details, and dimensions. Thus, many buttons do not reveal their true character and appearance in the photos or scans. When uncertainty exists, ask a fellow club member or a dealer to show you an actual example of the button in question. Printable worksheets for clear and colored glass and a color primer can be accessed with the links at the bottom of this page.
