How can I create a program to measure the internal pressure of a pressure cooker by changing the material used in the cooker?

Question

I know I have to include a system that uses: the melting point of the material, the value of the flame that will fall on the pan, the materials that will be used inside the pan and some more information. If someone could help... I'll be very thankful.

Answer 1

I was trying to find a material that allows the internal pressure to reach 60,000 bar. with a temperature nearly 1500 °C
