Product care

Are your products dishwasher safe?

Yes, all our products are dishwasher safe. You don't have to wash them by hand.

Do your plates fit in my dishwasher?

Yes, most of our plates should easily fit in your dishwasher.

An exception is our Unterplate/Serving plate, which may not normally fit in your dishwasher. With many dishwashers, however, the height of the middle basket can be adjusted. There are usually small levers on both sides.

Can your products go in the oven and microwave?

Yes, you can use our products in the oven and in the microwave up to 230°C.

However, make sure not to expose the ceramic to extreme temperature changes. For example, a hot plate from the oven should not be quenched with very cold water. And a plate from the fridge or freezer should not be placed in the hot oven. Otherwise cracks may form.


What material is your tableware made of?

Our products are made of high-quality and durable stoneware.

What is stoneware?

Stoneware is a subcategory of ceramics and is fired in a kiln at a temperature of up to 1300°C. These high temperatures allow the ceramics to "sinter" and then be waterproof even without glazing it.

What is the difference between ceramics, porcelain, stoneware and earthenware?

Porcelain, stoneware and earthenware are subtypes of ceramics and have different properties and compositions.

Porcelain is made from a very light clay with a high proportion of kaolin and fired at high temperatures. The pieces are usually covered with a transparent glaze, sometimes the raw material is already colored. Porcelain tableware is therefore usually white or pastel-colored.

Stoneware is a very strong and durable material that can be glazed in a wide variety of colors. The clay has a high proportion of silicate crystals, which enables a high firing temperature of up to 1300°C. These temperatures are necessary so that the ceramic is waterproof afterwards, even without a glaze.

Earthenware is cheaper to produce and easier to work with, but of lower quality than porcelain and stoneware. The clay contains more fat and, due to its composition, is only fired at lower temperatures. Therefore stoneware dishes are not completely watertight and in any case need a glaze. Stoneware is rather unsuitable for the dishwasher.

Stoneware and earthenware are often confused. However, since there are qualitative differences and the two types are usually very difficult to distinguish visually, you should pay very close attention to the designations.

All products in our shop are made of stoneware and are therefore particularly resistant.


Where and how are your ceramics made?

Our products are made by hand in a small manufacture in northern Portugal.

Because this process is so exciting, we have documented the entire production for you. Here you can see how our colorful plates are made from sand and clay, a lot of experience and time.

Where do the raw materials for your products come from?

The raw materials for our ceramics come from the surrounding area of our manufactory and are mixed and processed directly on site.

Colors and glazes

Why are there differences in color, shape and pattern within a collection?

Our products are coated with so-called reactive glazes which react with each other in the kiln and create different patterns. Some of our pieces are also glazed in two or more colors, so that the lower color sometimes shines through more or less.

The manufacturing process of our ceramics includes a lot of manual work, which is also reflected in the products. This makes every product unique.

What are reactive glazes?

Reactive glazes are so-called effect glazes, to which small metallic and/or mineral particles are added. These react with each other in the kiln, creating unique patterns that look a little different on each piece.

Each of our products is therefore unique.
