Mica is a mineral, not a recipe. It's not made of ingredients, but rather a naturally occurring substance.

However, if you are asking about the components of the mica mineral, it's primarily composed of:

* Silicon dioxide (SiO2)

* Aluminum oxide (Al2O3)

* Potassium oxide (K2O)

* Magnesium oxide (MgO)

* Iron oxide (FeO)

* Water (H2O)

The exact proportions of these components vary depending on the specific type of mica.
