MICACEOUS HEMATITE ('shiny ore') - Moretonhampstead, Devon
« backMICACEOUS HEMATITE
‘Shiny ore’ from Dartmoor
Pepperdon Mine, Moretonhampstead, Devon
Hematite is the main ore of iron and comes in many forms but perhaps the most unusual is micaceous hematite or ‘shiny ore’.
It consists of tiny sparkling, metallic grey, plate-like crystals that catch the light, and it often leaves a glitter of tiny particles when handled. The crystals have similar properties to mica, hence the name.
In the early 19th century micaceous hematite was used to dry ink before the invention of blotting paper. It is also a rust-inhibiter and was later used extensively as an additive to the paint used on railways, bridges and warships.
