2. Iron oxide - Wikipedia

   en.wikipedia.org/wiki/Iron_oxide

   Iron oxides feature as ferrous or ferric or both. They adopt octahedral or tetrahedral coordination geometry. Only a few oxides are significant at the earth's surface, particularly wüstite, magnetite, and hematite. Oxides of Fe II. FeO: iron(II) oxide, wüstite; Mixed oxides of Fe II and Fe III. Fe 3 O 4: Iron(II,III) oxide, magnetite; Fe 4 O ...

3. Ceramic colorants - Wikipedia

   en.wikipedia.org/wiki/Ceramic_colorants

   Ceramic colorants are added to a glaze or a clay to create color. Carbonates and oxides of certain metals, characterize most colorants including the commonly used cobalt carbonate, cobalt oxide, chrome oxide, red iron oxide, and copper carbonate. These colorants can create a multitude of colors depending on other materials they interact with ...

   Pieces can be grey, red, or white, painted with iron oxide or decorated with glaze. Shino glaze ( 志野釉 , Shino uwagusuri ) is a generic term for a family of pottery glazes . They tend to range in color from milky white to orange, sometimes with charcoal grey spotting, known as "carbon trap" which is the trapping of carbon in the glaze ...

6. Wash (visual arts) - Wikipedia

   en.wikipedia.org/wiki/Wash_(visual_arts)

   In interior design, a wash or color wash of paint on a wall can be used to create a textured effect as a faux finish. [2] In ceramics, a wash is typically a coloring oxide thinned with water applied to the piece to achieve an effect similar to a glaze. [3] Digital image creation software can have features that simulate the painting technique. [4]

7. Iron(III) oxide - Wikipedia

   en.wikipedia.org/wiki/Iron(III)_oxide

   Iron(III) oxide is a product of the oxidation of iron. It can be prepared in the laboratory by electrolyzing a solution of sodium bicarbonate, an inert electrolyte, with an iron anode: 4 Fe + 3 O 2 + 2 H 2 O → 4 FeO(OH) The resulting hydrated iron(III) oxide, written here as FeO(OH), dehydrates around 200 °C. [18] [19] 2 FeO(OH) → Fe 2 O 3 ...

8. Glass coloring and color marking - Wikipedia

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

   Ordinary soda-lime glass appears colorless to the naked eye when it is thin, although iron oxide impurities produce a green tint which can be viewed in thick pieces or with the aid of scientific instruments. Further metals and metal oxides can be added to glass during its manufacture to change its color which can enhance its aesthetic appeal ...
