Thank you for contacting the Rakow Library with your question.
Found your Grandmother’s hooded chimney shade in a 1973 Corning Glass Works Residential Lighting catalog. Attached is a copy of the pages. The next catalog we have of lighting products is from 1982 and the shape comes only in a clear Pyrex or a grape pattern/white satin. The grape design is in both catalogs. It was made in the Corning plant in Muskogee, OK in 1982 and I am assuming that your earlier chimney was made there as well.
Hope this answers your question. Please let me know if you need more information.
