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

一旦玻完成，就会被压成细小碎——玻渣。

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.

这些碎玻点低于新玻，因为新玻制作之初那些成已经混合在一起。
