Hammerscale appears in two forms: flakes and hollow spheroids. The flakes can vary greatly in appearance and size; however, their color ranges from a dark black to a lustrous blue or grey and their thickness from one to five millimeters. Like the flakes, the spheroids are also quite small but their size can vary.
The desired flake shape is achieved by controlled crystal growth in the axial and equatorial directions. The color purity and transparency of the effect pigments obtained by coating the Al 2 O 3 flakes with metal oxides can be attributed to the synthesis procedure yielding single-crystalline thin flakes [1] [2]
Whitewash aids in sanitation by coating and smoothing over the rough surfaces. Successive applications of whitewash build up layers of scale that flake off and, in the process, remove surface debris. The coating also has antimicrobial properties that provide hygienic and sanitary benefits for animal barns. [4]
Size and reflectivity of flakes is higher than conventional metallic paint as seen on this custom paint job. Metallic paints may be generically referred to as metal-flake paint, but a specific variation uses larger flakes of metal that are individually visible. Flakes with different colour effects may also be used within the same paint. [3]
The flakes are constructed of aluminium coated with glass-like magnesium fluoride embedded in semi-translucent chromium. The aluminium and chrome give the paint a vibrant metallic sparkle, while the glass-like coating acts like a refracting prism , changing the apparent color of the surface as the observer moves.
[6] [7] At least two modern reproductions of Scheele's green hue with modern non-toxic pigments have been made, with similar but non-identical color coordinates: one with hex#3c7a18 (RGB 60, 122, 24) and another with hex#478800 (RGB 71, 136, 0). [8] [9] The latter is the more typically reported color coordinate for Scheele's green. [10]

A fabric softener (American English) or fabric conditioner (British English) is a conditioner applied to laundry after it has been washed in a washing machine.A similar, more dilute preparation meant to be applied to dry fabric is known as a wrinkle releaser.
