A previous owner obviously gave up on this lamp - The wires were cut out, but the lamp was still stuck to the wall. Not a big fan of the broken lamp. Nothing dissolved the glue, the chisel wasn't working. So I tried the box cutter. The razor fit into a tiny crack the chisel didn't, and it just sort of popped off. I have to sand the glue down, but at least I don't have to decorate around a dead lamp anymore.
