1793 Glass Dish , First Balloon Flight in America

This is a glass dish I bought about 25 years ago . There is another like it posted on Collectors Weekly , from about a year ago . I am wondering if anyone has any information about this dish . The only other dish like it that I could find is in the collection of the Smithsonian National Air an Space Museum in Washington DC . I am searching for it's maker ! Please help ! I will post what I find. THANKS!!!
