I talked with a scientific glassblower friend, Sally Prasch, who told me she sometimes decorates petri dishes (and other scientific glass).
Other scientific glassblowers may add personal touches to the glass they make -- as a "whimsey." I did not find this documented in our books or catalogs.
This may be a fairly recent development because colored borosilicate glasses have become readily available now.

If you wish to talk with Sally, she is listed on the "Find a Glassblower" page, under the Northeast: http://asgs-glass.org/mo/index.php/northeast
The Corning Museum of Glass is currently closed to the public effective March 16 through April 22, 2020, as a precautionary measure for public health and safety. As a result, resources available to answer your questions are extremely limited. During this closure, you may be interested in searching our Ask a Glass Question FAQs or reviewing our Research Guides on various topics. We also highly recommend checking out The Corning Museum of Glass on YouTube for hours of artist demonstrations, lectures, and special events. Thank you for your patience.
