To make glass, three basic elements need to be fused together: 1. a vitrifying agent, Silica, introduced in the form of sand; 2. a flux, soda or potash, in the form of sulphate or carbonate (lowers the melting temperature of the silica) 3. a stabilizer, lime, in the form of carbonate (gives the glass greater resistance to water attacks) these three components are in fact found in glass compositions since the most remote times. Today the most modern glass, manufactured at the rate of thousands of tons per day is produced with the following composition: Vitrifiable mixture Yes O2 Ca CO3 Ca Mg (CO3) 2 Na2 OR AI2 100% 57.46% 10.56% 9.88% 2.96% Sand Limestone Dolomite Feldspar From 100 parts of the vitrifiable mixture 83 parts of glass are obtained and there are 17 parts of loss due to volatilization. Glass composition (compound in percentage%) Silica 72.0 Aluminum 0.7 Lime 10.7 Magnesium 2.6 Soda 13.5 Sulfur dioxide 0.5 The glass obtained in this way, thanks to its extreme versatility and ability to be cut, ground, hot forged and tempered, is nowadays increasingly widespread in construction, industry and custom. Esso riceve nella sua struttura praticamente tutti gli elementi dela tavola periodica, direttamente o sotto forma di ossidi, variando in diversa misura le proprie caratteristiche. L'introduzione di particolari composti metallici, sciolti o dispersi nella massa allo stato colloidale, conferisce al vetro capacità di assorbimento selettivo della radiaazione luminosa, e quindi colore: Composto Colore Ossido di Ferro Blu - Verde Ossido di Rame (oso) Rosso - Viola Ossido di Rame (lco) Blu - Verde Ossido di Cobalto Blu intenso Oro e Stagno colloidali dal Rosa al Porpora Selenio e Cadmio colloidali dal Rosso al Giallo Arancio Cobalto Selenio Ferro Bronzo Cobalto Selenio Ferro Cromo Grigio Caratteristiche fisico-tecniche dei prodotti vetrari: - Isolamento Acustico - Proprietà Meccaniche - Caratteristiche Ottiche - Proprietà Termiche - Resistenza al fuoco - Sicurezza nelle Vetrazioni Forward tweet ECOSANSPERATE scrl Administrative office : ZI Macchiareddu Cacip 7th street 09010 - Uta (CA) Tel / Fax : +39.070.9606010 E-mail : ecosansperate@tiscali.it VAT number 02603200920 Last news Glass ... what it is 07 August 2015 Armored glass and Pirex 06 August 2015 Useful links Conai CiAl Rilegno Comieco Corepla CoReVe Coou Cobat Recycle CIC Waste Lab Utilitalia Ecocerved © 2015 ecosansperate.it.
