Bituminous coal is an organic sedimentary rock formed by diagenetic and sub metamorphic compression of peat bog & swamp material. Its primary constituents are macerals: vitrinite, and liptinite. The carbon content of bituminous coal is around 60-80%; the rest is composed of residual water, air, hydrogen, and sulphur. It is graded according to its vitrinite reflectance, volatiles content, plasticity & ash content which in turn gave rise to specific uses e.g. smithing, coking or just general heating fuel. These particular examples are from the Carboniferous deposits in Lancashire. the samples are supplied by weight and come in a kilo bag with a label.

Cannel coal by it’s physical morphology and low mineral content is considered to be coal but by its texture & organic matter content it is considered to be oil shale. Although historically the term cannel coal has been used interchangeably.

Specimens of Bituminous Coal, collected from the Carboniferous deposits in Yorkshire. Bituminous Coal is an organic sedimentary rock, that forms by diagenetic and sub metamorphic compression of peat bog & swamp material. Its primary constituents are macerals: vitrinite, and liptinite. The carbon content of bituminous coal is around 60-80%. The rest consists of residual water, air, hydrogen, and sulphur. These specimens are available in multiple sizes and come in a white card tray with an information label.

Cannel coal by it’s physical morphology and low mineral content is considered to be coal but by its texture & organic matter content it is considered to be oil shale. Available by weight in lots of 1 kilogram.
Specimens of Lignite (Brown Coal), collected from Germany. Lignite is a soft, combustible sedimentary rock which forms by the natural compression of peat material. It has a high carbon content 25 – 35% & a moisture content up to 66%. The high volatile matter content makes it easier to convert into gas and liquid petroleum products than higher ranking coals. It is used almost exclusively for the generation of electricity in countries such as Greece & China. These pieces are Miocene in age. They are available in multiple sizes and come in a white card tray with an information label.

Anthracite coal specimens, a vitreous, high grade coal with a hard and compact nature, these samples are from the Carboniferous coalfields of South Wales, UK and are one of the coals which have fewer impurities and a high carbon contents. Available in optional sizes, each sample will come supplied in a card tray with a label.

Specimens of Puddingstone, collected from Hertfordshire, UK. Puddingstone is a variation of conglomerate, which is term used to describe a coarse grained sedimentary rock, featuring large, well rounded clasts in a finer grained matrix. It dates back to the Paleocene to Eocene period around 56 millions years ago. This particular rock is composed almost entirely of silica and has no porosity, likely contributing to its notorious hardness. This rare rock is only found in quantity at one locality in Hertfordshire. As such, it is becoming exceedingly difficult to obtain. This rock is available in multiple sizes and each piece comes supplied in a white card tray with information label.
Pumice specimens from the Lipari islands, Italy. Pumice is an igneous rock with a highly porous structure resulting from trapped gas bubbles as the lava was being ejected. The rock is usually very light & buoyant in water. Specimens are supplied in a card tray with label.

Specimens of Limestone, collected from Derbyshire. Limestone is a common, well known sedimentary rock. It consists of the calcium-rich shells, bones, and skeletons of the fauna that dominated during that period. It was laid down approximately 350 million years ago in semi tropical seas and comes from the Dinantian epoch of the Lower Carboniferous. This rock is very pure, about 98% soluble in rainwater (over time) leaving only residual clay. Its uses include aggregate, building stone, the manufacture of cement, paper & calcium carbide. Available in various sizes, each piece comes supplied in a white card tray with information label.

Adamellite granite also known as shap granite from Cumbria, famous for its large pink feldspar crystals his granite is well known. The samples come from the Shap Quarry, Shap Fell, Cumbria and are supplied in a polythene bag in lots of 1 kg with a label.
Snowflake obsidian is quite striking in appearance. It is characterised by the inclusion of radially clustered crystals of cristobalite, which when viewed at a glance, appear like snowflakes on the surface of the rock. These crystal clusters are set in an otherwise black vitreous matrix of obsidian, which is an naturally occurring volcanic glass, even exhibiting a conchoidal fracture. Cristobalite is a high temperature polymorph of silica, it can form as a result of the devitrification of the obsidian. These specimens come from Java, Indonesia and are supplied in card trays, sizes which are optional, each tray also has a small data label supplied.

Graphic Granite is a leucocratic igneous rock found predominantly in granitic pegmatites. It’s coarse intergrowths of feldspars display a Runic or Cuneiform configuration hence the term “graphic”
