- Talc Mineral Milling
Talc is a hydrated magnesium silicate. Talc deposits form from the transformation of high magnesium rocks by siliceous hydrothermal fluids. Most talc originates from the alteration of dolomite, or ultramafic intrusive rocks. Following this process, talc is always found in combination with other mineral (s). Carbonates and chlorite are the most ...

Talc is a widely used additive in the milling process throughout the world. While many neophytes to the business balk at the use of talc, it is an accepted industry practice, just not a very heavily publicized one. Talc helps increase yields when used with high quality fruit and also facilitates the milling of difficult fruit such as overwatered and/or over-ripe fruit.

The mineral is similar to talc but is used to create the frost in your lipstick or eye shadow. When you break down mica, it breaks down flat—like a mirror—so, depending on the particle size, you can go from club glitter to frosty to illuminating to just glowy. "When you rub mica into your skin pure, it disappears," describes Casale.
