What reading level is The Blowpipe Manual book?
To quickly assess the difficulty of the text, read a short excerpt:
when touched by the reducing flame, disappears, impart- ing to the flame, when consisting of sulphate of potassa, a bluish violet color, and, when of sulphate of soda, a reddish yellow. Sulphide of lithium, formed by the reduction of sulphate of lithia on coal, is also volatilized by an intense heat, but more difficultly than sulphide of sodium, and gives, instead of a pure white, a greenish white, thin crust, which touched with the reducing flame vanishes, coloring the flame caimine red. The s...ulphides of lead and b'lMnutk also belong here. Each of these sulphides, both in the oxidizing and the reducing flame, affords two different deposits of which the most volatile is white, and is a sulphate. When these deposits are heated in the reducing flame, that of lead disappears, communicating a blue tinge to the flame ; that of bismuth vanishes, but does not color the flame. The incrustation nearest the assay consists of the oxide of the metal, and may be recognized from its color, both while hot and after cooling.
