Musannaf Ibn Abi Shayba 13:2155

Abu Bakr narrated to us, he said: Hushaym narrated to us, from Mansur, from al-Hasan, that he used to see no harm in [exchanging] intact glass vessels for broken ones by weight, if they were better than the intact ones. And Ibn Sirin used to dislike that, unless it was weight for weight.
