Appearance

At first glance, armour glass looks identical to an ordinary pane of glass especially when it is framed and no glass section is unable to be seen. Since the glass is very thick, light transmission is low. Sometimes, it may look green because general glass contains iron and thick glass has much higher iron content. Thus, less iron content of ultra clear glass is, when necessary, selected to increase higher light transmission and eventually turns its transparency as close as single pane of glass.
