Compared to the process just described, thermal tempering (this is the name given to the processing performed to obtain tempered glass) involves:<\/p>\n<ul>\n<li>Very high temperatures (we are talking about over 600 degrees);<\/li>\n<li>Rapid cooling by air jets.<\/li>\n<\/ul>\n<p><span style=\"text-decoration: underline;\">The end result is a glass that is elastic, strong and incredibly resistant compared to the non-tempered variant.<\/span><\/p>\n<h3><em>The limits of floating glass<\/em><\/h3>\n<p>The above considerations lead us to identify what are effectively the limitations of floating glass that make it unsuitable for certain uses:<\/p>\n<ul>\n<li>Low level of safety;<\/li>\n<li>Low mechanical resistance;<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2><strong>The floating glass proposed by TF VETRITALIA<\/strong><\/h2>\n<p>For the<strong><a href=\"https:\/\/www.tfvetritalia.com\/en\/vetri-per-elettrodomestici\/\"> household appliances industry<\/a><\/strong> and for the production of glass for stoves and ovens, our company offers different glass proposals: <strong>coloured glass, coated, decorated and with laser markings.<\/strong><\/p>\n<p>The<strong> heat treatment<\/strong> and <strong>screen-printing<\/strong> process allow us to obtain a final product that is aesthetically pleasing but, above all, characterised by considerable mechanical resistance.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>From the manufacture of tables and small tables, through mirrors and windows, to doors and household electrical appliances: float glass is the most common type used in the manufacture of products in which glass is one of the raw materials.
