Answer :
In order to make pottery water-tight, it should be fired at a minimum temperature of a. 1350 degrees Fahrenheit. At this temperature, the clay undergoes a thermal reaction that leads to the formation of a solid, water-tight structure. This is due to changes at a molecular level, where heat causes the clay particles to fuse together, changing their physical characteristics and thus making the pottery resistant to water.
Looking at other materials, like quartz for instance, it melts into a viscuous liquid at 1600 °C and cools to form an amorphous structure, called silica.
It's important to note that a temperature difference of one degree on the Celsius scale is 1.8 times as large as a difference of one degree on the Fahrenheit scale. For example, water boils at 100 °C (1.00 Atm pressure) in the Celsius scale, and this temperature is equivalent to 212 °F in the Fahrenheit scale.
Pottery needs to be fired at a minimum temperature of 1350 degrees Fahrenheit to become water-tight. At this temperature, the structure of the clay changes, and it becomes fused together and resistant to water. Comparatively, other materials such as quartz undergo similar changes at different temperatures.
