Diatomite is silica-rish sediment formed by microscopic algae, and has many uses, such as face powder, fire-proofing and insulation, neutral filler, and as a filter in several industrial processes. However, one of the greatest causes of interest in Skye Diatomite was its potential use as a substitute for Kieselghur by Alfred Nobel in the production of Dynamite in Nobel's new Scottish factory at Ardeer in Ayrshire during the 1880s.

Nobel eventually found a better source of material, but the Extraction of Diatomite nevertheless began in Skye at Loch Cuithir in 1886. The Diatomite was transported by tramway to be processed at Invertote, production continuing until 1913. The industry was briefly revived between 1950 and 1961, using road transport.

The principal remains of the Invertote works are a large, rubble-built, rectangular-plan roofless building (NG5201 6049). It has been entirely gutted, but fragmentary remains include a large cast-iron flywheel from a steam engine, and a cast-iron wall-mounted bearing box. The other surviving structure is a kiln (NG5201 6052), comprising a lower chanber or firebox built from Scottish firebricks (produced at the Star Works, Glenboig, Lanarkshire, and Etna Works, Armadale, West Lothian), onto which has been constructed a circular-section fireclay-brick column encased by an outer layer of sheet steel. The exact functions of the processing building and the kiln are uncertain, but it is likely that the latter was used for drying purposes.
