Pattern: Advertising / Specialty
Identifiers / Alternate Names: This category includes pyrex items that were customized for companies, produced for advertising purposes, or made for special events such as one time employee gatherings. While there might not be much distinction between this category and the "Promotional / Unknown" category, we felt that because of the large number of advertising items (mugs in particular) that they should be placed in their own category to avoid cluttering the already crowded promotional category. In most cases, these items are not sets but single items.

Sizes and ID#s: No number (300 ml)
This is another of those specialty mugs that were made for in-house Corning events. It’s a Diagonal D Handle in the 1410 series that holds about 10oz (300ml), but once again the bottom of the cup is not marked as Pyrex, but marked only as “Corning”. This is very similar to the marking on the Pyrex Labware mug that we have.
I have doubts whether this is Pyrex, but because of the shape we are going to include it here anyhow. This was produced for a Charleroi Anniversary Banquet in 1972 and features those words in darker blue (different than the familiar lighter slate blue that is present on the Labware mug).
The reverse side of the mug reads simply “Corning” in block letters in that same darker blue color. I have no idea on the mintages on these types of mugs, but it can’t be a huge amount. One bad thing about living on the West coast is that there nearly zero chance of ever finding them because all the Corning facilities are on the East coast… it means that I spend a lot of time looking for them on Ebay!
