Staining makes it easy to distinguish between colorless quartz, yellow K-feldspars, and pink plagioclase, making quantitative work (e.g., point counting) quick and accurate. On the other hand, staining obscures details of the stained minerals, and sometimes also of other minerals too, and therefore makes routine petrographic work more difficult.

One of the key phases in the manufacture of porcelain is the in situ formation of mullite(2). Mullite is an aluminosilicate material and depending on stoichiometry, has the formula 3Al 2 O 3 2SiO 2 and 2Al 2 O 3 SiO 2.It is a very rare mineral in the ground, but it is understood to form at around 1,100 °C from feldspar and kaolin type materials during the kiln firing process.
