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, […]

ELB 9+2 the glass edge grinding polishing machine from Bovone: beyond standard grinding with groove and arris in one step

Bovone’s high specialization in the production of glass processing machines has enabled it to launch the Elb 9+2 glass edging polishing machine, an ambassador of a useful and appreciated technological innovation. Elb 9+2 is, in fact, a glass edge grinding and polishing machine that allows glass grooving and arrises in a single pass at very […]

Why should we care about quartz?

Quartz is beautiful. It shimmers in light and its rainbow of colors have stoked the imagination of everyone from admirers seeking spiritual healing to young geoscientists. But most quartz on Earth does not look like the gorgeous minerals we admire. Most of its forms are lackluster, dull and not translucent. But quartz plays important roles […]


quartz, widely distributed mineral of many varieties that consists primarily of silica, or silicon dioxide (SiO2). Minor impurities such as lithium, sodium, potassium, and titanium may be present. Quartz has attracted attention from the earliest times; water-clear crystals were known to the ancient Greeks as krystallos—hence the name crystal, or more commonly rock crystal, applied […]

Elettromeccanica Bovone’s ELB 10+1: the ultimate glass working machine for versatility and productivity with dubbing device integrated

Glass processing is an essential part of many industries, including construction, automotive, and furniture production. One of the key components of this process is the use of a specialized glass working machine. Elettromeccanica Bovone is a leading manufacturer of Glass processing machines, and their ELB 10+1 model is a prime example of the high-quality machinery […]


The term ‘silica’ can be misleading. It is important to understand the difference between ‘silica mineral’, ‘silicates’, and ‘silica glass’. Quartz is the best example of a natural mineral that is almost pure silicon dioxide (it is the most abundant mineral on planet earth). Other ceramic minerals like feldspar and clay contain some ‘free silica’ […]
