2. Set up the retort stand and clamp alongside the tripod and gauze mat.
3. place the beaker of ice on the gauze mat and gently clamp the thermometer so that it is held upright

The bottom of your thermometer should be low enough to still be covered by water when the ice melts,
but not touching the bottom of the beaker.
