Tempered glass

[wsiegel]

How can I tell if this is tempered glass. There were no markings on it and it was very thin. Thanks

Break it?

Seriously, if I can't see the etching because it's not there or because of dirty glass I defer it to be verified and recommend the safety/tempered glass for enhanced safety, or some such.

The id bug on tempered glass is imparted during the tempering process and since tempered glass can not be cut... if there is no bug visable call it out if it is in a location that would require it.

From GlazingCodes.Org:

The federal law (CPSC 16 CFR 1201 for Category I or II or ANSI Z97.1-2004), combined with mandates in building codes, requires that each pane of safety glass be permanently marked. The monogram or logo includes the manufacturer, type of glass and the standard to which it complies. Other information may be included. The federal law is designated by its identifying number "16 CFR 1201-II." Look for this designation. If it is not included, the glass may not be safety glass. The 2000 International Building Code and its predecessor regional model building codes specify compliance with the federal law.

Fully tempered glass cannot be cut after fabrication. Every pane would typically include a monogram. Some laminated glass can be cut. Although large sizes intended to be cut to size are generally monogrammed at two opposite corners, the monogram may not be on every pane. In this case a certificate of compliance is furnished attesting that the larger pane was properly marked.

Dosen't have to be a big hammer Greg, but it sure will go out as a bang.

Wasn't glue-chip was it? Hard for me to tell
