  2. Non-stick surface - Wikipedia

    en.wikipedia.org/wiki/Non-stick_surface

    For example, a mixture of titanium and ceramic can be sandblasted onto the pan surface, and then fired at 2,000 °C (3,630 °F) to produce a non-stick ceramic coating. [19] Ceramic nonstick pans use a finish of silica (silicon dioxide) to prevent sticking. It is applied using a sol-gel process without the use of PFAS. [20] The coating layer of ...

  3. Conservation and restoration of ceramic objects - Wikipedia

    en.wikipedia.org/wiki/Conservation_and...

    The danger of mechanical cleaning is the potential for the surface to break or become scratched with a tool. Dusting is used when dirt is not strongly adhered to the surface of the ceramic and is carried out by either a brush or a soft cloth. Large ceramic vessels are cleaned with a delicate vacuum cleaner with a soft, muslin-covered head ...

  4. Glaze defects - Wikipedia

    en.wikipedia.org/wiki/Glaze_defects

    Crazing is a spider web pattern of cracks penetrating the glaze. It is caused by tensile stresses greater than the glaze is able to withstand. [1] [2] Common reasons for such stresses are: a mismatch between the thermal expansions of glaze and body; from moisture expansion of the body; and in the case of glazed tiles fixed to a wall, movement of the wall or of the bonding material used to fix ...

  5. Ceramic glaze - Wikipedia

    en.wikipedia.org/wiki/Ceramic_glaze

    Ceramic glaze, or simply glaze, is a glassy coating on ceramics. It is used for decoration, to ensure the item is impermeable to liquids and to minimise the adherence of pollutants. [1] Glazing renders earthenware impermeable to water, sealing the inherent porosity of earthenware. It also gives a tougher surface.

  6. Environmental impact of paint - Wikipedia

    Measures can be taken to reduce its environmental effects, including accurately estimating paint quantities so waste is minimized, and use of environmentally preferred paints, coating, painting accessories, and techniques. The United States Environmental Protection Agency guidelines and Green Star standards can be applied. [not verified in body]

  7. Low emissivity - Wikipedia

    en.wikipedia.org/wiki/Low_emissivity

    Low emissivity (low e or low thermal emissivity) refers to a surface condition that emits low levels of radiant thermal (heat) energy. All materials absorb, reflect, and emit radiant energy according to Planck's law but here, the primary concern is a special wavelength interval of radiant energy, namely thermal radiation of materials.

  8. Seasoning (cookware) - Wikipedia

    en.wikipedia.org/wiki/Seasoning_(cookware)

    The coating known as seasoning is formed by a process of repeatedly layering extremely thin coats of oil on the cookware and oxidizing each layer with medium-high heat for a time. This process is known as "seasoning"; the color of the coating is commonly known as its "patina" - the base coat will darken with use. [9]

  9. Coating - Wikipedia

    en.wikipedia.org/wiki/Coating

    A coating is a covering that is applied to the surface of an object, or substrate. [1] The purpose of applying the coating may be decorative, functional, or both. [2]
