• Details:  We don't typically carry laboratory items but we ran across these at an estate sale and thought they were so cool (and cute), we just had to bring them to you!  This is not our niche, so we're grouping the entire lot of vintage crucibles as one item.  There are 4 crucibles, all have the filter bottoms.  Three are a darker clay and have a stamped brand: "Coors USA 07" in printed-block lettering.  One is a lighter color and is embossed with the name "Coors" in cursive then "USA, 60151".  We have limited knowledge on these items so there's very little we can tell you about them beyond the description.  These were used in the laboratories for metal, glass, and pigment production and are supposed to withstand high temperatures but we make no guarantees.  These are used and have writing on them.  They make great display pieces, especially when displayed en masse by color/and patina.  Also make great seed starter cups because they already have drainage built in.   
• Material:  Fireclay mixed with other materials
• Dimensions:  Each is Approx. 2.0 inches Tall, 1.5 inches in Diameter (top opening).
• Condition:  Vintage - Used.  Very Good Vintage Condition.  No chips, scratches.  Lots of patina which we feel is acceptable, and desirable, due to age/use/wear.  There is hand writing on them.  Please review all pictures and make sure you love this item before purchasing, we can't accept returns.  Please remember these are VINTAGE and ANTIQUE items, they are NOT new, every effort has been made to show any scratches, wear and tear and imperfections. 

John Herold, an immigrant from Austria, moved to Golden, Colorado in 1909 and incorporated the Herold China and Pottery Company on December 10, 1910. Adolph Coors assisted Herold by providing a building he owned in Golden, once home to the Colorado Glass Works.  In late 1914 Colorado voted to adopt prohibition laws so Adolph Coors turned to ceramics to keep his family in business. John Herold decided to leave Golden in early 1915 so Adolph Coors' two sons, Adolph, Jr. and Herman, took over the Herold China and Pottery business. In 1920 the Herold China and Pottery Company became the Coors Porcelain Company. Several lines of dinnerware and hotel ware. Also during the 1920's, Coors Porcelain became a world leader in the production of labware, becoming the supplier to inventors like Thomas Edison among many others. When Prohibition was repealed in 1933, the Coors Company returned to brewing beer, but continued manufacturing labware.  During WWII, (the war lasted from 1939 to 1945), labware was not being imported, there was a need and Coors Porcelain concentrated on technical porcelain products.  Coors Ceramics Company was the only firm to consistently provide quality labware.  Joseph Coors Sr., one of Adolph Jr.'s sons, took over the pottery in 1946 and continued to steer the company towards industrial ceramics and technology.  By 1960 they were producing enough labware to supply the entire nation.   In 1986 Coors Porcelain became Coors Ceramics.   Since the year 2000 what was once Coors Porcelain Company has become CoorsTEK, a manufacturer of technical ceramics as well as high quality scientific and analytical labware. Their corporate headquarters is still located in Golden, Colorado.
