Very nice. I have always seen them with a test tube, never thought to use a beaker.
I've been wanting to make one but I wasn't sure I'd even use it. I've heard the heat sometimes melts the stem. What did you use for the heat source, candle/tea light or stove top? What kind of alcohol spirit or isopropyl, proof?
I wouldn't try but I wonder how it'd affect a meerschaum pipe. Maybe it would help color it.
