What it is

Mammoth Clay Company is a moist-clay company and pottery supply house in Oklahoma City, Oklahoma. Its site title reads “Mammoth Clay - Clay Mixers, De-Aired Moist Clay, Glazes & Refractories.” Through the official shop at mammothclay.com and a walk-in storefront at 4221 N Walnut Ave, it sells its own Mammoth Clay bodies in low-, mid-, and high-fire ranges, plus L&R and Laguna moist clays. It also carries glazes (Mammoth and L&R lines, AMACO, Coyote, Mayco, Penguin Pottery, Kiwi, Ritual), dry clays and raw materials, tools, kiln furniture, Skutt and L&L kilns, Pacifica and Skutt wheels, pugmills, and Soldner clay mixers. It is a supplier with an official online shop, not a teaching studio and not a membership guild.

Who it’s for

Studio potters, schools, clay studios, and hobbyists in Oklahoma and across the U.S. who need moist clay, glazes, raw materials, kilns, wheels, or a clay mixer. Customers can pick up at the Oklahoma City storefront, call in an order, or have it shipped. Product pages ask buyers of 250 lb or more to call or email, which suits studios and schools buying in volume. Shipping covers the 50 U.S. states, and Soldner mixers also ship internationally (FAQ). No classes or open studio are offered on the site.

Why it’s listed

This is the first-party Mammoth Clay Shopify shop (mammothclay.com) with a printed Oklahoma City storefront address, phone, email, weekday hours, live product pages with prices and stock status, a newly launched 2026 clay body, and printed shipping and return terms. It is not a scraped directory card and not an Amazon storefront.

Notes

• Category is Supplier: sells its own Mammoth moist clay and resells clays, glazes, raw materials, tools, kilns, wheels, and mixers through mammothclay.com and an Oklahoma City storefront. No classes or open studio are offered on the site.
• First Oklahoma listing on Clay Plaza in any category, adding the southern Plains / south-central U.S. (Oklahoma previously appeared only as a region named in ClayHouston’s show eligibility). Away from recent RI/WI/LA, CA/HI/MO, SC/CO/AZ, OR/PA/FL, and TX/MI/MN geos. Mammoth clay is mentioned as a stocked brand in the existing Clay King listing, but Mammoth itself has never been listed. It resells already-listed brands (Laguna Clay Company, AMACO) but is a separate maker and retailer. Keep separate from Lapidary / Mahjong / Bee / Bonsai directories.
• Bag size: product pages print a price per unit but do not state the bag weight in the visible text. The shop’s public product data gives a shipping weight of 11,340 g (25 lb) for the bodies checked (Jezero, Sweet Tooth, Mastodon Mid Fire, Cimarron). Treat prices as per bag and confirm the size with the shop.
• The About page has a heading and no body text. No founding year or ownership history is stated on the pages checked, so none is claimed here. The relationship between Mammoth and the L&R clay and glaze lines it sells is not explained on the site.
• Currency evidence at check: footer © 2026; the homepage “NEW CLAY BODY!” Sweet Tooth (shop data shows the product created Aug 6, 2026 and published Sep 15, 2026); live in-stock product pages and prices. No closure notice.
• The contact page gives one hours line (“8:00 AM – 4:30 PM, Closed on Weekends & Holidays”). It does not list weekday-by-weekday hours.
• No Amazon or affiliate links were found on the pages checked.
• Prices were transcribed from official pages checked on 2026-10-08 and may change.
• Not affiliated with Clay Plaza.
• No Clay Plaza contact, purchase, quote request, or publication action was taken.
• First-party logo saved beside this listing as mammoth-clay-company.jpg (Stacked_Logo_Full_Color_Registered.jpg site-header logo from the Shopify CDN, 1200 × 1237).
