Mostly children work in the glass furnaces. About 20,000 children are engaged in glass bangle industry. Their parents don’t know that it is illegal for children to work in high temperatures, in dingy cells, without air and light. Children work in these hot furnaces all day long, often losing the brightness of their eyes. In dark hutments, boys and girls sit with their fathers and mothers. In the flames of oil lamps, they weld pieces of coloured glass into circles of bangles. Their eyes are more adjusted to the dark than to the light outside. Thus, they lose their eyesight even before they become adults. The children often have to sit for long hours to weld the glass. It eventually leads to their stunted growth and many other physical deformities.
