Corning Ware Marks and Mayhem - General Dating of Corning Ware Back Stamps

I think it's time to touch on the dates associated with certain marks.  I have avoided this subject, primarily because with Corning Ware, it is not an exact science.  The Hub Machine began forming Corning Ware at the Martinsburg plant in 1961, but there were other plants producing Corning Ware as well.  Greencastle and Main Plant, just to name a couple.  These plants did not necessarily receive new molds for new shapes at the same time, nor would they changed their stamp format at the same time....  So all dates given have a little wiggle room.

1958-1959 - Embossed Bottom Stamp

1959 - Embossed Bottom with stylized flame Stamp (7 inch skillet, 9 inch skillet, 2 1/2 quart Saucepan)

1960-1961ish - Blurry Blue Ink Stamp (may or may not have Pyroceram printed)

1962-1968 - Basic Model Number with stylized flame Stamp

1969-1972 - "for Range & Microwave" Stamp (with or without small Cornflower)

1972-1979 - Hologram Stamp (VERY hard to see unless tilted to the right angle in the right light)

1979-1985/86 - Block Stamp

The Block Stamp first appeared on the Designer Casseroles (DC-Series) in 1977, but moved to square Corning Ware in 1979/80. 

This mark would be revisited for the later Microwave Plus line in the early 90s and remained with the MR-Series until they were discontinued.

1985 - 1999 - 2nd Embossed Stamp (Block mark was still used on Roasting Pans until 1987)

For traditional square Corning Ware, this mark was under the Handle Lug, except for Petites, which were embossed on the bottom, but with measurement in milliliters.

For French White/Classic Black and Casual Elegance, it is located on the bottom.

There are myriad small modifications such as "for Range and Microwave" mark having or not having the cornflower... For a while in the mid 70s, this "cornflower stamp" was reused on Teapots and Percolators.  Also, Hologram stamps were never used on either of these pieces.

Hope this helps to narrow down the dates of some of your pieces.

Where is your Corning Ware??

Corning Ware Microwave Browners and Micromates Booklets - Scanned

After all the information I have posted regarding Electromatic Skillets and Table Ranges, I figured it was time for some scanned documentation regarding the other pieces that receive the most questions. 

The Microwave Browning Skillets and Grills......

and the "Micromates" (which is just Corning's later brand name for Microwave Browning Skillets)

Though I have posted links in the past, that point to the preheating times, hopefully these booklets will answer any questions about Usage (Do's and Don't's) and Cleaning along with the preheating times of various models.
