How to prevent hot cracking of glass, glass curtain wall, building glass and glass.

There is only one key point to prevent this phenomenon, that is, "don't produce excessive temperature difference on the same glass surface." If there is no temperature difference, there will be no thermal stress, so it is impossible to cause thermal cracking. As for the measures, the first consideration is to make glass that can withstand this temperature difference. This kind of glass exists.

For example, when the temperature difference is large, the thermal stress inside the glass is very small; (such as borosilicate glass), it belongs to this category, but it is expensive because of its special composition, such as hardening it; It's also good, but laminated glass can't be tempered like tempered glass: another idea is to improve the strength of the glass edge first, which is not easy to realize in practical operation because I don't know how to use it. Therefore, except in every stage of design, construction and use; Attention should be paid to prevent hot cracking, and there is no other suitable solution.
