You need to use any substance which has a very high degree of consistency with regard to expansion as a function of temperature and one that doesn’t evaporate as a result of the temperature is an evacuated chamber.
Water should do; the chamber is the most critical. It must have a superior integrity to flaws on aging in its use.
