    Ceramic glazes come in many types and fire at different
    temperatures.  Ceramicists tend to use a system called "cones" for
    determining firing temperature--this dates back to the days before
    modern pyrometers were available.  Chances are, your Raku glaze has
    "cone xxx" on the label.  If we know that, we can go to a chart and
    determine the actual temperature in degrees.  What does the label
    say?
