Water boils at 100 degrees Celsius and freezes at 0 degrees Celsius. These phase changes make the thermometer useful for a narrow range of temperatures - those between 1 and 99.
Another issue is water expands as it gets close to its freezing point. Water is most dense at 4 degrees Celsius. Lower than that the water begins to expand to line up in its crystalline form. That cuts the lower range of the thermometer to 4 degrees Celsius.

Water freezes at 0° C.
Water also EXPANDS when it freezes.
Therefore your thermometer would break when the water froze.
If it is an oven thermometer, the same principles apply and the same thing would happen when the water turns into steam.

because of the low denisty of water. you will need a very, very long bar of glass to make a water thermometer.
