In this set the amber piece is part of a lamp base. The CD 120 shows deformed threads that doomed it as a throw away. The deformed skirt piece is from a CD 136 and has the letters B & O embossed. The slag chunk is an example of the many colorful chunks found in sizes up to a softball. Every color from crystal clear to blackglass has been found as well as swirl combos, two, three and fourtones, and incredible "junk in glass". These slag glass pieces are some of my favorites.
