Glassblowing
open-in-new
<p>Glassblowing is a glassforming technique that involves inflating molten <a href="/facts/Glass/hezRsAGf">glass</a> into a bubble (or parison) with the aid of a <a href="/facts/Blowpipe_(tool)/SwzJ9bbV">blowpipe</a> (or blow tube). A person who blows glass is called a <i>glassblower</i>, <i>glassmith</i>, or <i>gaffer</i>. A <i><a href="/facts/Lampworking/kdLSGdmR">lampworker</a></i> (often also called a glassblower or glassworker) manipulates glass with the use of a torch on a smaller scale, such as in producing precision laboratory glassware out of <a href="/facts/Borosilicate_glass/Ywaqt7Ic">borosilicate glass</a>. </p>
