During the recent excavations of the harbour area of Classe, a large amount of glass was recovered and evidence of glass working was identified [1,2].
For example, in the United States, in 2001, approximately 11 million tons of glass entered the municipal waste stream, but only about 2.4 million tones (22%) of this glass was recovered and recycled.
Flyash is a fine, glass powder recovered from the gases of burning coal during the production of electricity at Norochchole, thermal power plant in Sri Lanka.

Mag-z-db4, a wound bead, contains high aluminium levels and malayite (Cr-Sn sphene), a phase also detected in some soda glass beads recovered at the Antsiraka Boira necropolis on Mayotte Island (twelfth-thirteenth century) [28].
Present study was conducted to improve a sludge collected from a water treatment plant near Kalu river in Horana, Kalutara and the additive material is flyash, which is fine, glass powder recovered from the gases of burning coal during the production of electricity at Norochchole, thermal power plant in Sri Lanka.
[23] Sintering and densification were observed to result in strength recovery; with sintering time approaching τ s, the strength of single-phase, defect-free melt (glass) was recovered.
Interestingly, the Glass dynamics recover a temporal sequence of attractors, that is qualitatively similar, although not identical, to that obtained using the Boolean model.
