Copper oxide, including black cupric oxide and red cuprous oxide, is one of the most reactive metallic coloring oxides. The range of glaze colors produced depends in part on the kiln atmosphere and the composition of the base-glaze recipes. -Copper oxide and copper carbonate can produce greens, browns, blacks, turquoise and reds in glazes.

Kaolin is registered as an OTC skin protectant drug with the FDA (Category I, allowed concentration 4-40%). This means that if you want to sell a finished product containing kaolin and you make a skin protectant claim (incl. minor cuts, scrapes, burns, chapped skin and lips, poison ivy, poison oak, poison sumac, and insect bites), kaolin must then be …
Samples Q and DW had a high amount of calcium oxide content compared to the other kaolin samples at about 19.97%and 12.72%, respectively. The presence of calcium could significantly influence the characteristics of the resultant geopolymer binder; it has been reported that the existence of calcium-based compounds increases the …
The main components of kaolin are the chemical compounds SiO 2 with around 46% and Al 2 O 3 with around 38% [47]. The quality of natural kaolin fillers is defined in ISO 3262, Part 8. It contains the purest kaolin with a minimum content of 90% kaolinite (aluminum silicate containing water of crystallization).
No significant differences between commercial metakaolins were found, but some facts must be evidenced: i) relatively high content of titanium oxide related with the presence of anatase; ii) the ...

While this clay is usually white, kaolinite can also be a pink-orange-red hue due to iron oxidizing and causing rust. Red kaolin clay indicates that there are high levels of iron oxide near where it is found. This type is most suited for people wanting to prevent signs of aging. Green kaolin clay comes from clay that contains plant matter.
ions that would be required by carbonation reaction, kaolin was treated with lime based on the result of the modified ICL test according to the definition presented by [2].
