    Characteristics of Porcelain

    The following phenomena may occur even in products that are shipped as good products after inspection. Please be aware that these phenomena are unavoidable due to the manufacturing process and that  they are characteristics of the product.

    Bleeding or Blurring of Logo
    The ORIGAMI logo is painted by a technique called underglaze painting, which means that it is printed under the glaze. Therefore, some of them may fuse with the glaze, causing blurring or bleeding. Also, since the logo is coated on top, it will not fade or come off during use.
    Iron Dust
    Even white objects contain iron in the clay from which the vessels are made, which appears as black spots on the surface when the vessels are fired.
    Pinholes
    Glazed vessels may have small indentations that look like pins. This is a phenomenon peculiar to ceramics in which organic matter attached to the fabric during glazing is baked and forms small dents, and is not a defect.
    Individual Differences in Glaze (Colour and Texture)
    Porcelain has a variety of expressions depending on natural conditions such as seasons and temperatures, as well as the glaze and the heat used during firing. For this reason, even vessels made of the same material will vary in colour and texture after firing. The two items below are the same colour, but the colour intensity may vary depending on the time of production.
    Uneven Colour or Texture
    The thickness of the glaze may vary depending on the shape and thickness of the vessel, and the exposure to fire may cause the colour and texture to be uneven in some areas within a single vessel.
    Fine Surface Irregularities
    This can occur during the firing process and is not considered a defect.
