Details on Glass Identification

The Corning Museum of Glass does not have a formal identification program. However, the Curatorial department often is able to provide information about glass objects within our areas of specialty of Ancient, Islamic, European, American, Modern and Contemporary, and Science and Technology. We cannot answer every question due to the volume of inquiries we receive and the limited research available about certain common forms of glass, but we will do our best to provide you with some information to the best of our abilities and knowledge.

What We Can Do

  • Examine photographs of glass objects for purposes of identification.
  • Tell you, as best we can, how, when, where, and by whom the glass was made. Our ability to identify objects depends on a range of factors including information provided, curatorial work load and expertise, and previous research.
  • Suggest additional resources from the Rakow Research Library or the internet for you to learn more about your glass.

What We Can’t Do

  • Provide a value, appraisal, or authentication, or comment on rarity.
  • Comment on objects which are not glass, including ceramic, rock crystal, and stone.
  • Identify Pyrex, Corelle, or CorningWare. For information on patterns and other research questions related to these brands, please visit our website for all things Pyrex, Pyrex Potluck. Questions and comments about the history of Pyrex production may be directed to the Rakow Research Library's Ask a Glass Question.
  • Identify objects brought or sent to the Museum or give an identification over the phone.
  • Automatically accept offers to donate or sell objects, which must be evaluated on a case by case basis and in accordance with our collections management policy.

What We Need From You

  • High-quality, non-blurry jpg images, including details of any markings or signatures present on the glass and photographs from different angles, including the underside or bottom of your object.
  • A description of how and where you got the object and how long you or your family have had it. Often, the history of the object can tell us a lot about it.
  • Questions! What do you want to know about your glass?

To request information about your glass object from our Curatorial staff, please submit photographs of your object using our Ask a Glass Object Question service and selecting "Object Identification or Information," or mail your images to: Curatorial Department, Corning Museum of Glass, One Museum Way, Corning NY, 14830.
