A History of Gregorian Copper

I love writing about the history of companies that interest me.

Gregorian Copper: A Family Business

P. R. Gregori and his brother Fred started Gregori Copper in 1946 in Southern California. The newly formed Gregori Copper company began modestly in the garage of the Gregori brothers' parent's home in Capistrano Beach. In two short years, they were able to move into their permanent facility in San Clemente. Soon, Gregori Copper was shipping copper items all over the U.S. and to Latin America.

P. R. Gregori, the artist/founder of the company, was educated at the Butler Art Institute in Youngstown, Ohio. After WW II, he received hands-on experience at Craftsman Studios in Laguna Beach, California, an artistic commune in the 1920s that evolved into a facility that produced a wealth of copper products in the Arts and Crafts style. This experience inspired Gregori and his brother Fred to start Gregori Copper.

The Mark

To be sure the copper piece you're looking at is a genuine item from the Gregorian factory, look for the copper foil label on the back. You'll also find pieces that are marked with an engraving of cursive handwriting script that says Gregorian Copper along with a number.

The number refers to the item itself, kind of like an old-fashioned bar code. It doesn't refer to the quantity of that particular piece that was made at the factory, like when art pieces are numbered. This number refers to the model number of the particular item.

The Manufacturing Process

While Fred Gregori handled sales, P.R. Gregori not only ran the manufacturing site but was also the artist behind the copperworks. He designed all of the copper products and even made his own tools and dyes. Using large sheets of copper in various gauges, Gregori fashioned utilitarian but extremely beautiful items using hand tools and even a spinning lathe.

Each object was hand-beaten and finished with an acid bath. Gregori developed a special bluing process that gave each piece a depth of color, and then he hand-rubbed them with steel wool, creating either a solid copper finish or a satin finish. To ensure that the copper would retain its color, it was lacquered with a gun sprayer and then baked for 40 minutes.

The Gregorian Copper 313 Bowl

The Gregorian Copper 313 Bowl is one of the most famous pieces from the Gregorian factory. It measures approximately 6.5 inches wide by 2.5 inches tall. This bowl has a ruffled edge and a raised leaves and berries motif in the center of the interior. The hammered copper is beautiful, and the pedestal foot gives it an elegant feel.

What Happened to the Company?

At the height of Gregori Copper's business, it employed 25 people and garnered annual sales of half a million dollars. In 1968, the company was sold to Sunbell, and the copperworks was eventually moved to Albuquerque, New Mexico, and continued to produce beaten copper products well into the 80s.

P.R. Gregori and his wife moved to New Mexico but soon returned to California, where P.R. opened a dining establishment, Papa Pio's Italian Restaurant, in Dana Point. Sunbelt sold the company twenty years ago to a firm in Lemmon, South Dakota, that became Gregorian Inc. This company now produces giftware using various metals and resins, including delicate jewelry made with copper, but nothing like the classic Gregorian Copper pieces that the Gregori brothers made.

This 8" high solid copper coffee pot by Gregorian is 5 1/2" in diameter at the bottom, and 3 1/2 " at top is over 35 years old. It is in very good condition but does exhibit a few age-related tarnish spots in several locations that enhance its overall patina.




Sold on 11/16/12 for $11.48.

This beautiful Gregorian bowl is 9" in diameter, 2 1/2" tall, and has crimped edges for extra strength. The Gregorian copper label is still affixed to the bottom. Gregorian used stick-on labels on most pieces (rather than embossing/etching) as labels did not show through to the front of single-ply pieces such as this bowl.

Do you own any Gregorian copper pieces? Let us know which ones you'd like to acquire.

Shellykevin on July 14, 2020:

I purchased a small coal skittle ( with handle). I believe that is what it is. It only has a signature and then 615 with a circled R on the bottom. I only paid $2 for it and just curious what it actually is and if it an original since it didn’t have the stamp on it with the guy on the side with the name ? I would think these pieces would have more value than what I am seeing on eBay. Just curious. Thank you

Jane on July 08, 2020:

My son just brought a gift he purchased for me. A beautiful tray with raised fruit in the center and a fluted edge. It has the Gregorian sticker on the back and designed to be hung. Breathtakingly beautiful. Thank you for talented artisans and wonderful sons.

Susan Keil on April 04, 2020:

I have a engraved 24" double roped tray. It does not have a number under the signature. I have looked online and have not come across at tray that is that large or double roped accent outer edges. I have not found a match like mine. It appears to be authentic. Do you have knowledge of Gregoria Copper trays that size?

Kay Ekwall on April 02, 2020:

I have a beautiful piece, in mint condition, with the engraved script mark which I believe my parents purchased on one of their trips to New Mexico. It is a leaf base as in the look of some of the candy dishes, but has a curved piece on the front, like a tube that one could put flowers into it, with water or not. It hangs on a wall. I am giving it to my niece as a family keepsake. I am an artists/crafts person myself, and I know how much work, and time, efforts, and loving craftsmanship goes into each piece of them and so shocked that they are not valued as much as they should be. They are true works of art, many to be considered antiques these days and just the copper in them is worth more then the prices people are asking for them. Just a big shout out to the founders, designers, people who worked there and made them and contributed to a big of American history. Thank you. And to the family members on down, their legacy is something to be so proud of with their family.

My husband worked for Gregorian Brothers Copperworks in San Clemente in the 50's and 60's and as such we acquired aroung 60 pieces or so. Have a couple of duplicates but that's all. Would like to know if there is a cataloge of product avalilable to see what the company originally made. I believe that the engraved pieces were some of the firstpieces made and that there are least two different adhesive labels that have been used since that time. I think that they play a part in the companys movement from one location to another.

anonymous on October 27, 2011:
