hello , these beads really look similar to beads I dismantled on part of an old french chandelier - as soon I find them , I will post some pictures .
Il y a environ trente ans , j'ai démonté un vieux lustre , pour réutiliser les perles sur un accessoire de théâtre . le marchand l'avait daté du 18 ème ( le lustre ) - les perles étaient semblables aux vôtres , exepté la couleur - les miennes sont vraiment incolores
In SE Asia, the variables for glass beads are that they are either imported from China or India, or they were locally-made. There were, formerly, glass-beadmaking industries in Thailand and Vietnam.
"Khmer beads" only indicates "worn by the Khmer." It is not an origin.
The beads look like plain furnace-wound glass. Without something like a chemical analysis, and a corpus of analyses to compare with, not much more can be determined. All plain furnace-wound beads look more-or-less the same, from any industry. But most of the oblate beads I have seen from this region look Chinese to me.
Thank you Jamey. I am not really surprised about these two possible origins. Plain furnace-wound beads in SE Asia are a very fuzy subject to me. I find they all look the same, so your answer is somehow a relief. Thank you.
