What is the Cooling rate for SiO2 glass formation?

    What is the Cooling rate for SiO2 glass formation???


    I am trying to make a chunk of SiO2 Glass and was wondering what should be the Cooling Rate & what is the minimum temperature required for the glass transition?

    Does adding impurities like Calcium oxide or Lead oxide effect the cooling rate?

    Ps; I have an electric furnace with good insulation & was terrified by learning about very high cooling rates required... So I will be thankful to know the minimum required rate of cooling...

    Thanks in advance
