If it has a low specific gravity, of about 1.1 , burns and carbonizes in a hot flame then it is amber. If it has a specific gravity of about 2.7, and scratches glass easily, then it is some variety of silica, such as quartz or agate. If it barely scratches glass, and has a specific gravity of between 2.4 and 2.7 then it is most likely just brown bottle glass.
