Common Questions

Designed for daily use

We throw our stoneware thick to handle real kitchens. Here is what to expect from Clay Heart pieces.

Are they truly dishwasher safe?

What makes them durable?

Yes. We fire our stoneware to high kiln temperatures, vitrifying the clay so it survives the high heat and water pressure of any standard dishwasher.

We throw our pieces with heavy bottoms and reinforced rims. This extra clay at key stress points prevents chipping during clumsy sink washes.

Can I use them in the microwave?

What is your shipping policy?

Absolutely. Our lead-free glazes and dense stoneware clay body do not absorb moisture, meaning they stay cool to the touch while heating your morning coffee.

We pack every order in fully recyclable, heavy-duty paper wraps. If a piece somehow breaks during transit, we replace it immediately, no questions asked.
