Identity HelpSlag or volcanic glass? Found on lakeshore, Utah
2nd Aug 2022 01:09 UTCDan Sko
I found this item washed up on a lake shore near Ogden, Utah. At a first glance it looks like slag, but I am not sure. It is amber in color and has inclusions resembling those found in natural amber except that this clearly feels and sounds like glass. I could not identify any air bubbles within. Any help would be greatly appreciated.

Most glass melts at between 1,400 to 1,600 degrees Fahrenheit and bush fires can certainly reach those temps.
Some metals are melted in bush fires. Magnesium alloy wheels, for example, can turn into amazing flowing masses, and aluminium melts at 1,220 F.
