Acid sulfate soils are known to exhibit coloured mottling
and nodules that are indicative of secondary Fe-minerals (Fitzpatrick and Shand 2008).
Whatever the techniques used, it is clear that this fire clouding or mottling
was deliberately produced for aesthetic effect.
As basic dental care for the island population was minimally existent, is was inferred that most likely increased concentrations of natural fluoride in the drinking water of the island of Brava was responsible for the high incidence of enamel mottling

Germination of nonscarified seeds was not significantly correlated to mottling
except at 30[degrees]C.
It is suited for aqueous inks, paints, adhesives, coatings, and resins and has been shown to reduce mottling
in liquid flexo and gravure inks, particularly on nonporous surfaces such as plastics, films and foil.
Relevant soil properties include texture, coarse fragments, structure, matrix colour, mottling
, and chemical and mineralogical properties.
The company's inks are said to be ideal for mottling
, stamping, silkscreening and marking.
We saw a similar mottling
of teeth," as well as malformations in their mineral structure, she told Science News.
One recycler, for example, has seen times when the carbon black for masking mixed-color mottling
has cost much as the recycled resin feedstock itself.
