Ray Eames Ceramics???  

Looks like an amateur potter...
Looks like an amateur potter project to me.
That's a stretch to assume RE stands for Ray Eames. It's the kind of thing that people who don't know anything about anything say.

What a reach. RE could stand...
What a reach. RE could stand for anything...

nice stamp.
Maybe Ralph Emerson was a potter too!
I've never seen such a clean and highly rated seller.
I wonder where that connection came from.
I really do like the stamp. Clean square graphic.

It is well documented
That both Charles and Ray were very impressed with the work of Maija Grotell, ceramist and teacher of the potter's art at Cranbrook. The Syracuse archives of Maija Grotell include soem letters with Charles Eames. She was born on in 1899 in Helsingfors (Helsinki), Finland,and studied at the Central School of Industrial Art "Ateneum," where she graduated in 1920, she joined a textile firm as an artist while continuing her study of pottery. She immigrated to the United States in 1927 and joint Cranbrook after a number of other instructor or teaching jobs in 1938.
What impressed the Eames' most was her work ethics. Apparently one could find her at any hour of the day in the ceramic studios. In her twenty-eight years at Cranbrook she taught dozens of students, Ray Eames was one of them.
There are a number of reason why these products are not by Ray Eames. In spite small differences in height thes pieces are made by a potter with good experience on the potters wheel. It takes more than an introduction course to make this kind of products. I am sure that if Ray Eames had that skill it would be mentioned in the many publications about her and her husband. I have never seen it mentioned. The clay that is used is quite different from the clay that was used in Cranbrook. This kind of stamp is not something you quickly cut in a small piece of end wood. This is the stamp of someone that takes pottery seriously and has him our herself made a professional stamp. Finally, the bold unrefined shapes are not in line with the refinement usually produced by the Eames'....so....very very unlikely
