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.

Values: Check below on Ebay for approximate prices
Sizes and ID#s: #473 (1 quart)

We had some difficulty deciding whether this belonged in the “Promotional” category or the “Advertising / Specialty”. In the end, we decided on the latter because we have been putting the one-off items that are dated in that category. Also, people are not as likely to come across this item so it’s not as important that it be represented in the picture pattern reference - where we try as much as possible to reduce clutter in an increasingly long list of patterns.

Pyrex Love - Blue Chip Week

This is a standard sized #473 1 quart blue casserole with white writing that was made as a limited promotion, we believe for employees of Corning. We are unclear as to the exact nature of the event, but according to the writing on one side of the casserole, it commemorated “Blue Chip Week” which occurred April 21-27, 1963. That side of the casserole also says “Corning Glass” inside the same white outlined circle, and there are two additional circles on either side that have the word “Excellence” in it.

Pyrex Love - Blue Chip Week

The other side of the casserole consists of a single white circle with the words “Charleroi Family Day April 27, 1963“. We are unclear how often Corning produced these “Family Day” promotional items, but we do know that they did do it more than once. We do have this mug which is also for a Family Day, but that was in the 80s. We also know that they produced special pieces like these for anniversary banquets and other occasions. Collecting these special Pyrex promo items is fun, because the variety seems endless!

The casserole that we got had a standard 470-C clear lid. As far as we know this casserole did not come with any sort of carrying tray or caddy. We also wonder how they were given out at the event - whether they were boxed or if they simply gave them out as is to employees at the dinner. We would love to hear your story if you received any of these promotional items in person, or know someone who did.

Here are two closeups of the writing on each side of the casserole:
