Bovone stone straight-line edgers: discover how the pluses of the Stonedge 15/45 and Stonedge 15/45 radius models adhere to the needs of kitchen countertop manufacturers

The Stonedge 15/45 and Stonedge 15/45 Radius models represent the natural evolution of the Stonedge 11/45 model in the panorama of stone straight-line edgers. Among the range of straight-line edging machines for stone, the Stonedge 15/45 model is particularly suitable for the processing of kitchen countertops because, in addition to the possibility of simultaneous edging […]

Silica Group of Silicate Minerals

Quartz was the mineral upon which the Stone Ages were based. With few exceptions, most early stone tools were fashioned of quartz. Outcrops of quartz that were suitable for tool manufacturing were targeted by some of the earliest known mining activities and the mined quartz was traded across vast distances, even before humans began to […]

What is Quartz?

A widely distributed mineral on the Earth’s surface, quartz is a crucial constituent of igneous, metamorphic, and sedimentary rocks. It is formed in igneous rocks as magma cools and silicon dioxide crystallises. Quartz is highly resistant to chemical and mechanical weathering and can form at all temperatures. This is why mountaintops and beaches, sea, and […]

Uses of Quartz in Glass Making

Geological processes have occasionally deposited sands that are composed of almost 100% quartz grains. These deposits have been identified and produced as sources of high-purity silica sand. These sands are used in the glassmaking industry. Quartz sand is used in the production of container glass, flat plate glass, specialty glass, and fiberglass. Quartz glass sand: […]


Quartz refers to a specific chemical compound (silicon dioxide, or silica, SiO2), having a specific crystalline form (hexagonal). It is found is all forms of rock: igneous, metamorphic and sedimentary. Quartz is physically and chemically resistant to weathering. When quartz-bearing rocks become weathered and eroded, the grains of resistant quartz are concentrated in the soil, […]
