Limestone consists mainly of the minerals calcite and aragonite, two crystallisation forms of calcium carbonate. Other minerals occur in more or less varying proportions.
Limestone can belong to several types within the sedimentary rocks. However, the majority of limestones are of biogenic origin, i.e. they were formed and deposited by living organisms.
In most cases limestones have a light, grey to greyish yellow colour. By admixtures of other minerals (for example iron compounds) also stronger, above all red colors occur quite frequently. Bituminous limestones can also be dark grey to black in colour.

Glass chunks are a noble garden accessory that can be used for any object design.
In contrast to natural stones, exclusive glass chunks can be used to set impressive light accents in private gardens, parks and public gardens. An attractive appearance of the filling material can be achieved by alternating layers of natural stone and glass chunks or by creative patterns in combination with LED lighting. Light gabions can also be optionally combined with water, for example as a fountain with integrated water chute or a small waterfall. In the dark, the light gabions unfold, a fascinating play of light that is difficult to escape. Light gabions are thought through down to the last detail and convince not only with their attractive appearance but also with their high-quality materials.
It is a volcanic ejection product with bubble-shaped pores and a rough surface. The reddish-brown and predominantly glassy solidified dark brown sweat slags are extracted in open-cast mining, whereby the loose slag layers are directly conveyed and solidified patients are dissolved with the aid of explosions. The lava is crushed and classified according to grain size.Look:
