These stoneware bowls are hand thrown on a potter's wheel only a mile from my house in Oxnard, California. I have two color styles to choose from: sky blue with a grey glaze accent around the middle and green with blue. I have both styles in my kitchen.
These bowls are made of stoneware, not earthenware, which you find with mass-produced pottery. And the difference is felt instantly when you hold stoneware in your hands. They feel more sturdy because they are.
Stoneware is fired at much higher temperatures than earthenware. The high temperature (2000-2400 degrees) used to fire stoneware turns clay into stone and the glaze into glass, making the products more durable and scratch-resistant.
You will also find stoneware evenly distributes the heat of your hot food like soups and stews. And if all that wasn't enough, stoneware is chemical free and does NOT leach toxins into your food like other materials.
The same potter made me a handful of spoon holders with similar glaze colors (see the final two pictures). Other ways I use mine are for bar soap or to hold rings when I have my hands in dough or doing dishes. You can find them with this link.
