Example Sentences
- "Baldwin's phosphorus is prepared by melting nitrate of lime in a crucible or ladle for about ten minutes; it is then poured into an iron pot, or mould, previously heated, and has the property, like Canton's phosphorus, of absorbing light when exposed to the sun, and emitting it when taken into a darkened room."
