  2. Thermochromism - Wikipedia

    en.wikipedia.org/wiki/Thermochromism

    Thermochromism is the property of substances to change color due to a change in temperature. A mood ring is an example of this property used in a consumer product although thermochromism also has more practical uses, such as baby bottles, which change to a different color when cool enough to drink, or kettles which change color when water is at ...

  3. Glass coloring and color marking - Wikipedia

    en.wikipedia.org/wiki/Glass_coloring_and_color...

    Uranium (0.1 to 2%) can be added to give glass a fluorescent yellow or green color. [8] Uranium glass is typically not radioactive enough to be dangerous, but if ground into a powder, such as by polishing with sandpaper, and inhaled, it can be carcinogenic. When used with lead glass with very high proportion of lead, produces a deep red color.

  4. Chemical coloring of metals - Wikipedia

    en.wikipedia.org/wiki/Chemical_coloring_of_metals

    In the case of titanium, niobium, and stainless steel, the colour formed is dependent on the thickness of the oxide (which is determined by the anodizing voltage). Chemically coloring a metal is distinct from simply coating it using a method such as gilding or mercury silvering , because chemical coloring involves a chemical reaction, whereas ...

  5. Temperature sensitive glass - Wikipedia

    en.wikipedia.org/wiki/Temperature_Sensitive_Glass

    Temp sensitive glass tile. Temperature sensitive glass is a glass material that reacts to ambient temperatures radiated off of other surfaces, e.g. hands or water. The liquid crystals beneath the glass surface impact color upon temperature. [1] There are three main phases of these crystals: nematic, smectic, and chiral.

  6. Titanium dioxide - Wikipedia

    en.wikipedia.org/wiki/Titanium_dioxide

    Titanium dioxide, also known as titanium(IV) oxide or titania / t aɪ ˈ t eɪ n i ə /, is the inorganic compound derived from titanium with the chemical formula TiO 2. When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891. [4] It is a white solid that is insoluble in water, although mineral forms can appear ...

  7. Titanium - Wikipedia

    en.wikipedia.org/wiki/Titanium

    Titanium is a common material for backpacking cookware and eating utensils. Though more expensive than traditional steel or aluminium alternatives, titanium products can be significantly lighter without compromising strength. Titanium horseshoes are preferred to steel by farriers because they are lighter and more durable. [115]

  8. Sea glass - Wikipedia

    en.wikipedia.org/wiki/Sea_glass

    The color of sea glass is determined by its original source, and most sea glass comes from bottles. Besides pieces of glass, colored sea pottery pieces are often also found. [3] The most common colors of sea glass are kelly green, brown, white, and clear that come predominantly from bottles of beer, juices and soft drinks and fishing floats ...

  9. Hydrargyrum medium-arc iodide lamp - Wikipedia

    en.wikipedia.org/wiki/Hydrargyrum_medium-arc...

    Unlike regular incandescent halogen lamps where a halide gas is used to regenerate the filament and keep the evaporated tungsten from darkening the glass, the mercury vapour and the metal halides in HMI lamps are what emit the light. The high color rendering index (CRI) and color temperature are due to the specific lamp chemistry.
