· To measure the hardness of a mineral, Mohs scale is used. It is a 110 scale. Diamond is rated as 10 in that scale, and very harder than talc, which is rated as 1. Metal. Metals are known to human kind for a very long time. There are evidences to prove about metal usage back in 6000 BC.
As for the natural source, chemical weathering of heavy metal enrich rocks and minerals makes them available to aquatic environments and sediment (Reza and Singh, 2010). However, the natural source of heavy metal is related to the mineralogy of the specific region ( Karbassi et al., 2008 ).
The Big Brown lignite mine near Fairfield, Freestone County. There are many nonpetroleum, or nonfuel, minerals found in Texas. Some are currently mined, and others may have a potential for future development. Still others are minor occurrences only.

Luster: A mineral's luster is the overall sheen of its surface – it may have the sheen of polished metal, or that of an unpolished metal that is pitted by weathering – or it may have the sheen of glass, or look dull or earthy, etc. Luster should not be confused with color: A brassyellow pyrite crystal has a metallic luster, but so does a shiny grey galena crystal .
Minerals with a specific gravity under 2 are considered light, between 2 and average, and greater than heavy. Most minerals with a metallic luster are heavy. The specific gravity may slightly vary within a mineral because of impurities present in the minerals structure.
· While red causes the most problems, most other colors of standard tattoo ink are also derived from heavy metals (including lead, antimony, beryllium, chromium, cobalt .
