	The Copying Pencil: Composition, History, and Conservation Implications
		Methyl violet found success as a copying ink because of its high tinctorial value and brilliant violet hue which allowed it to produce multiple strong copies.
		Methyl violet's intensity of color is imparted by the highly conjugated organic systems which characterize its derivatives.
		Specific hues of methyl violet derivatives are determined by the number of methyl groups present in the molecule.

		It is shown that rhenium in the form of perrhenate forms a complex with methyl violet, which may be extracted by benxol and toluol.
		The absorption spectrum of a solution of the perrhenate complex with methyl violet in toluol was studied.
		The color intensity of a toluol solution of the rhenium complex with urethyl violet is proportional to the rhenium content and, therefore, the extracted complex of perrhenate with methyl violet may be applied for the colorimetric determination of rhenium.
