Low-melting glass based on the products of phosphate ores

The possibility of obtaining low-melting glasses with the use of phosphate ore processing products as one of the charge components has been investigated. Glasses of different shades of green, yellow and brown with satisfactory properties have been synthesized. The resulting glasses have a unique decorative effect that reproduces the texture of ornamental stones. Tab. 4, ill. 2, bibliography: 3 titles.
