Sulphur is the 16th element in the Periodic Table; and is important for its role in biology, ecology, industry and mineralogy.

Sulphur is part of of many minerals, including,  important ores of many metals, for example galena (PbS), Cinnabar (HgS), sphalerite (ZnS2), and Sulphur (FeS2). Sulphur also exists as a free element which is not combined with other elements.  Elements that exist in the free state, such as gold and silver, are described as “native elements”, and are considered minerals. Native sulphur is is found in sizable quantities around volcanoes.

Sulphur plays an important rolein biology, especially in the structure of protein molecules, which are the little machines that enable our bodies to function. Such proteins include hormones like insulin and antibodies that enable us to fight infection. Because of its biological role, sulphur has an ecological role as it cycles between the non-living world  and the food chain.

And then there is us, humans,  We’re good at finding uses for things we encounter; including sulphur. In fact Sulphur compounds are so ubititquitous in the 21st century culture that society would collapse without them. In fact sulphuric acid  is the starting material for making so many products that it is a measurement of the degree of industrialization is sometimes determined by the amount of sulphuric acid it consumes.  We make indispensable products  that depend on sulphur, yet we pollute our environment with it. It is now time to look at the good, bad andugly sides of sulphur

He has been collecting rocks and minerals, off and on since He was  10, when his aunt gave him a rock collection. Thus began a collecting odyssey which has grown into a frenzy over the last 25+ years resulting a sizeable collection of just about anything imaginable that is related to minerals.
