A Note on the Heavy Minerals Present in Some British Glass-making Sands
JSGT 1945 V29 T266-T267
The heavy mineral content in sixteen British sands which have been used in varying amounts for glass-making has been determined by separation in bromoform. It varied from 0·03 to 0·30%. The minerals identified were magnetite and limonite, ilmenite and leucoxene, tourmaline, kyanite, zircon, rutile, garnet and chromite.
