  Potash is often used as a soil nutrient.  In some West African cuisines it is often used (if anyone can tell me more about this, I’d be indebted).  It is composed of KCO3 and KNO3 among other compounds.  Here is Potash with plane polarized light.

 Here is Potash with polarized light and you can see the birefringent KNO3.
