• Season Ceramic Wares

About Seasoning earthenware

Ceramic is not as strong as porcelain or semi-porcelain, and its high water absorbency makes it susceptible to staining and, in rare cases, water leakage.
We recommend that material number 1 be sealed before use.
Material No. 9 should be treated by cooking porridge before use.
*Sealing reduces the absorption of cooking ingredients and stains. However, it does not prevent them from being absorbed completely.

• Microwave Safe

About Microwave Safe

A microwave oven heats or cooks food very quickly using short electromagnetic waves, namely, microwaves. In most cases, the microwaves heat the water content of the food. However, in some cases, the microwaves concentrate on the carbonized (burnt) parts of the food, causing the temperature to rise higher than the other parts. For example, the microwaves concentrated on the carbonized (burnt) parts of stir-fried vegetables can create a large temperature difference in /on the tableware item, which may cause breakage. In addition to water content, oil content is also heated. The oil has a higher boiling point than the water, so it heats up at a higher temperature, creating a very large temperature difference between the parts that contain oil and the parts that do not, which can cause breakage.

・Never soak hot tableware in water or place it on the cold kitchen counter. Avoid rapidly heating frozen foods or putting [the cold tableware just taken out of the refrigerator] in the microwave. A rapid change in temperature will lead to “crazing” (chaps) or breakage.

※The products with gold or silver paintings, or applied with particular glazes are not microwave safe. We put a “Do Not Microwave” sticker on those items, so please confirm it.

※Accessories etc., made of other materials are excluded from microwave safe items.

Notes on the use of Ovens

・Wipe water on the surface of tableware before putting it in the oven. Never soak hot tableware in water or place it on the cold kitchen counter. Avoid rapidly heating frozen foods or putting [the cold tableware just taken out of the refrigerator] in the oven. A rapid change in temperature will lead to “crazing” (chaps) or breakage.

・Never soak hot tableware in water or place it on the cold kitchen counter. Avoid rapidly heating frozen foods or putting [the cold tableware just taken out of the refrigerator] in the microwave. A rapid change in temperature will lead to “crazing” (chaps) or breakage.

・In cleaning, do not use a metal scrubber, etc. to get rid of the burns or strong dirt and so on resulting from cooking, which may damage the surface.

・High heat may change the color of tableware, but there is no problem in terms of use. It will be restored to the old color after cooled.

Open Fire Safe

The material of this product is heat-resistant ceramic. It can be used over an open flame; it cannot be used in an induction cooker.

This product is made of heat-resistant ceramic.

○ Some of the surface may have cracks (penetrations) at the time of purchase, and others may become penetrated as they are used.

○ The clay particles are coarse and moisture from the food placed in the vessel may seep out.

○ Insufficient drying can cause the following.

・ When put on fire, the moisture absorbed by the vessel may seep out from the sides and burn

.

・ If stored with moisture remaining in the vessel, stains and mold can easily form

• Strong Color Shade Variations

Strong Color Shade Variations

Each piece has strong individual color shade variations. Affected by glazes and natural firing conditions such as changes in temperature, humidity and other climate elements and also how to receive the fire in the kiln chamber, each piece has own expression. It is really difficult to make the completed ware exactly same in color by firing and glazing even when the same materials are used. 100 pieces show 100 kinds of expressions, as it were.



• Strong Color Irregularities

Strong Color Irregularities

There are strong color irregularities of applying a glaze or slip, which are different from part to part in a piece of ware. For example, some parts are glazed thinly or thickly depending on the shape of the ware. That leads to part-to-part differences in appearance of the clay in a piece of ware.



• Glaze or Slip Drips

Glaze or Slip Drips

The glaze or slip may look like dripping. There is unevenness of a glaze or slip when they are applied to ware by hand. There also appear glaze drips or slip drips, which are caused by the glaze or slip flows during firing.



• Pinholes

Pinholes

Pinholes may be seen clearly on the surface. Pottery (earthenware) is mainly made from earth, and green ware contains a lot of air while biscuit firing. While glazed firing, this air inside the biscuit ware becomes air bubbles, which remain and look like small holes on the surface of the glazed part. Those small holes are called pinholes.



• Crazing (Chaps)

Crazing (Chaps)

Crazing (having chaps) may appear clearly on the glazed part. The “direct” crazing means having chaps originally. The “aging” crazing means having chaps over time as you use the tableware item. There is a difference between the shrinkage rate of the glaze and that of the clay, so crazing occurs. Note that those cracks do not come from the damage of tableware items. They might appear just before use, but it is no problem in terms of use. They appear on the surface of pottery (earthenware) and semi-porcelain.



• Iron in Powder

Iron in Powder

Iron in powder may be seen clearly on the surface. Pottery (earthenware) is made from earth, which contains iron. After firing green ware, iron appears on the surface in the form of black dots. Red or black earthen clay contains much more iron, and as a result, not a little iron in powder may appear on the surface of tableware items made from this type of clay.



• Metal Marks

Metal Marks

Metal marks may appear by using metal cutlery where knives, forks or spoons touch the surface of dishware leaving black or gray lines. This is due to adhesion of metal particles on dishware with regular use of cutlery. These marks are not technically scratches, but are tough to remove.
