Alunite: Meanings, Properties and Powers The Complete Guide

Apr 27, 2019 This is an ancient stone discovered in the 1500s and has since then been excavated to manufacture alum. Alum has served various different purposes throughout history in ancient locations like the Roman empire, ancient China, and ancient Egypt. One of its main purposes was to dye fabrics with color, used mainly by the Romans.

This is not a very known stone and was discovered in ancient times. The history of the alum is different, and it is found in ancient China, Ancient Egypt and was found in the Roman Empire. The Romans would use this stone to dye fabric and the name was given aluminite but was changed to Alunite later.

Jarosite Wikipedia

Jarosite is an iron analogue of the potassium aluminium sulfate, alunite. Solid solution series. The alunite supergroup includes the alunite, jarosite, beudantite, crandallite and florencite subgroups. The alunite supergroup minerals are isostructural with each other and substitution between them occurs, resulting in several solid solution series.
