Details on Glass Identification

The Corning Museum of Glass does not have a formal identification program. However, the Curatorial department will try to provide information about glass objects within our areas of specialty of Ancient, Islamic, European, American, Modern and Contemporary, and Science and Technology.

PLEASE NOTE: We cannot answer every question due to the volume of inquiries we receive. A curator has many job responsibilities, including creating exhibitions, making new acquisitions, developing programming, and conducting research. We simply do not have the resources to respond individually to the more than 500 inquiries we receive every year. Inquiries received in person or by telephone will not be considered.

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

  • Guarantee we will respond to your question.
  • 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.
  • If you are an artist, collector, or dealer, please include as much documentation about the work as possible, including biography, artist’s statement and CV, website address, press materials, and other supplementary information.
  • 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.
