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

旦璃分拣完成，就会被压成细小的碎——璃渣。

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.

这些碎璃的熔点低璃，因为的璃制作之初那些成分已经混合在起。
