Built to Look Like a Boutique Set and Wash Like Everyday Dishes

Each detail fixes a specific complaint we found in 1-star dinnerware reviews.

Scratch-Resistant Satin Glaze

Vitrified to 6.5 Mohs, the closed-pore glaze gives stainless steel nothing to grind against. Cut steak right on the plate with no pencil-line streaks.

Cool-Grip Microwave Firing

Fired at 1,260°C until water absorption drops below 0.5%. No trapped moisture means the base stays grab-safe while your food heats.

9mm Raised Spill-Guard Lip

A gently upturned rim keeps pasta sauce, pan jus, and dressing on the plate instead of your placemat or lap.

Universal Dishwasher Fit

Tapered rims slide upright between Bosch, KitchenAid, Whirlpool, and GE tines without leaning or clanking.

How the HearthStone 12 Holds Up at Home

Cut Right on the Plate

Description

Why it doesn't scratch: Cheap matte plates use soft, silica-heavy glaze over low-fired clay, and that rough surface shaves steel off your forks. HearthStone is kiln-fired at 1,260°C (2,300°F), so the glaze fuses into a smooth satin surface that cutlery glides across.

Why the bowls stay cool: Porous earthenware soaks up dishwasher water through the foot ring, and the microwave heats that trapped water. HearthStone absorbs under 0.5%, so the base stays under 118°F in our 3-minute reheat test.

Our guarantee: Use the set every night for 30 days. Cut steak on it, run it through your hottest cycle. If you see gray streaks, burn your fingers, or just don't like how your table looks, get 100% of your money back. Each set also carries a 2-year chip and glaze warranty.

Finally a matte cream set that doesn't look like a #2 pencil drawing after steak night

Spent $220 last year on trendy matte plates and after ONE dinner with normal forks the centers looked like someone drew all over them with a #2 pencil. We've used the Cosari HearthStone 12 every night for three weeks—serrated steak knives, heavy forks, the works—and there isn't a single gray metal mark on them. Also the slight raised lip ('blate' style) keeps lemon butter and salad dressing from running onto our counter.

Fits our Bosch dishwasher prongs and upper cabinets flush

Watch the rim thickness if you own a Bosch dishwasher! Our last flat-bottomed matte set had thick 90-degree walls that wouldn't fit between the lower prongs and chipped immediately. The tapered raised rim on these slots right into the rack with room to spare. And at 10.5 inches across, our 11-inch upper cabinet doors actually close flush without hitting the dinner plates.

Bowls don't turn into molten lava in the microwave

Why do half the stoneware bowls online get hotter than molten lava in the microwave after 60 seconds while my soup is still lukewarm in the middle?! I tested the HearthStone bowls with leftover chili for two minutes straight and could actually pick the bowl up by the rim without an oven mitt. Total game changer for quick lunches.

No chalky knife screech

The tactile screech of a knife on cheap unsealed matte ceramic makes my skin crawl. These have a smooth satin-matte vitrified glaze so utensils glide quietly across the surface. Still gives you that zero-glare organic speckled look without the chalkboard nails effect.

Every guest asks if they're from East Fork or Crate & Barrel

Bought two sets so we have matching service for 8. The warm cream glaze with subtle dark mineral speckles makes literally anything you cook look 10x better. Left red pasta sauce and turmeric curry sitting on one overnight on the counter just to see what would happen, and it rinsed right off with zero yellow staining.

Real restaurant heft—just know they aren't lightweight glass

I wanted stoneware with real restaurant heft so they don't slide around on the table, not paper-thin glass that sounds like a cafeteria. These feel substantial and solid in the hand. Knocking off half a star only because a full stack of 8 dinner plates is pretty heavy if you're lifting them into a high shelf, though the sanded foot rings don't scratch each other at all.

Sanded bottoms don't scratch our walnut dining table

Our previous stoneware had rough unglazed rings underneath that acted like sandpaper on our solid walnut table if you skipped a placemat. The foot rings on the HearthStone 12 are polished diamond-smooth. Even when stacked four high in the drawer, they don't grind grit into the plate below.

Deep 6-inch bowls actually hold a real portion of pasta or cereal

So many 12-piece sets give you shallow wide soup plates or tiny condiment bowls. These 6-inch bowls are deep enough for morning oatmeal, ramen, or a big scoop of pasta without sloshing over the sides. I love that it's a pure 12-piece set of plates and bowls without 4 useless tiny mugs taking up cabinet space.

Once you eat off raised-lip plates, flat rims feel wrong

We eat a lot of grain bowls and saucy stir-fries on the couch, and the gentle raised lip on both the 10.5-inch dinner plates and 8-inch salad plates keeps everything contained. Nothing slides off the edge when you're walking from the counter to the living room.

Warm cream color holds up under night kitchen lights

We returned another speckled set last month because it looked beige online but turned a cold concrete gray under our kitchen lights at night. The Cosari HearthStone 12 stays a genuinely warm, inviting cream color both in afternoon window light and under 2700K bulbs at dinner.

Frequently Asked Questions

Will forks and steak knives leave gray marks on the matte cream glaze?

Not in our testing. After 50 serrated steak knife strokes at about 4 lbs of pressure, we found no gray transfer under a macro lens. The glaze is vitrified at 1,260°C into a smooth 6.5 Mohs satin surface, so steel glides instead of grinding.

Do the bowls get hot in the microwave?

The foot ring stayed under 118°F after a 3-minute reheat, even straight out of a wet dishwasher cycle. Water absorption is under 0.5%, so moisture doesn't get trapped in the clay. Food itself will still be hot, as with any dish.

Will the plates fit my dishwasher and cabinets?

Yes for most kitchens. The 10.5-inch dinner plates fit standard 11.5 to 12-inch upper cabinets, and the tapered 9mm rims stand upright in Bosch, KitchenAid, Whirlpool, and GE racks.

Is the glaze lead-free and cadmium-free?

Yes. The glaze is lead-free and cadmium-free and food-safe tested.

What if a piece arrives broken?

Each set ships in drop-tested honeycomb dividers. If anything arrives cracked, send one photo and we ship a replacement piece within 24 hours. You don't need to return the broken one.

What exactly is in the box?

12 pieces for 4 people: four 10.5-inch dinner plates, four 8-inch salad or dessert plates, and four 6-inch, 26 oz deep bowls. No mugs are included.
