Principal component analysis using Mg, Ca, Zr, Ba, Sr and U suggests most samples belong to m-Na-Al sub-type 1, while a few belong to a new type m-Na-Al low Al low Ca. (The comparative m-Na-Al 1 glass samples are unpublished data from Sri Lanka and South India, the m-Na-Al 2 glass samples are beads from Chaul, Maharashtra, India [32], the m-Na-Al 3 glass samples are beads from Kopia, Uttar Pradesh, India [33], the m-Na-Al 4 glass samples are glass vessel fragments from Sumatra [34] and the m-Na-Al 6 samples are beads from the Juani School site on the island of Mafia in Tanzania [35])
