Silicon has stable isotopes '28' ~92%, '29' ~5% and '30' ~3%.
Oxygen has stable isotope '16' at >99 %, so effectively mono-isotopic.
Do the three Si isotopes have significant effect on melting point etc of their silica SiO2 ??
For a 'world-build' (*), I'm trying to figure how pure silica window(s) might be reinforced with pure silica fibre mesh / web. Without none-silica interlayer(s) or adhesive...

In theory melting point of heavier mono isotope is higher.
$$T_{28}<T_{29}< T_{30} $$
For an example D2O has melting point 3.82 degree Celsius.
We need an equation of melting point that includes mass of molecule to investigate the difference in quantity.
