http://www.gcsescience.com/ex8.htm Web7 de fev. de 2024 · The zinc chloride solidifies in one lump, but there are still crystals. They only have grown together. If it were a real glass, the reactivity would be the highest since there would be no packing. This can only be achieved with extreme rapid cooling. When cooling is fast but still takes some time, crystals grow.
