which is similar to that for the action of potassium hydrosulphide
upon gun-cotton.
4. Flowers of sulphur and slaked lime were boiled with water, till a
bright orange solution was obtained. This was filtered, and some
nitro-glycerin powered into it. The reduction took place much more
slowly than in the other cases, and more agitation was required,
because the nitro-glycerin became coated with sulphur. In a few
minutes, the reduction appearing to be complete, the separated sulphur
was filtered off. The filtrate was clear, and the sulphur bore
hammering without the slightest indication of nitro-glycerin.
This would be the cheapest method of decomposing nitro-glycerin.
Perhaps the calcium sulphide of tank-waste, obtainable from the alkali
works, might answer the purpose.--_Chemical News._
