Liquefying is melting. The melting point of aluminum is 660 C. The melting point of iron is 1537 C. Lead melts at 328 C. Glass melts at between 1400 & 1600 C – depending on the specific composition. The fire had to be in the ballpark of 1400 – 1500 C to melt the glass and aluminum, without fully melting the steel / iron. However, I can’t posit a guess about the heat source.

This is what we needed after the Paradise, CA fire. People asking the real questions. Thank you so much for doing videos like these.
