Once the glass is all separated, it's crushed into tiny pieces, called " cullet" .

一旦玻分拣完成，就会被压成碎——玻。

These cullets melt at a lower temperature than new glass, because the ingredients and have already been mixed and fused together when that glass was initially made.

这些碎玻熔点低于新玻，因为新玻制作之初那些成分已经混合在一起。
