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 […]

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, […]
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 […]
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 is the mineral form of silica powder used in ceramic glazes and clay bodies. It is the mineral that silica “wants to be” when cooled from molten to solid (it can be other things depending on the speed of cooling). Unlike silica glass, the quartz phase of silica is subject to inversion and accompanying […]
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 […]
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’ […]
Bovone’s BVA, the virtual assistant that accompanies the machines and plants sold and installed by the company, brings the Glass Industry 4.0 paradigm inside the customer’s production flow by assisting and guiding them in the initial stages of machine installation, set-up and start-up, and assisting them throughout the machine’s life cycle. The digitization of all […]
