Phillips, Metallurgy, p. 317. Faraday found in Wootz 0·0128–0·0695 per cent. of aluminium, and attributed the ‘damask’ of the blades to its presence. Karsten, after three experiments, and Mr. T. H. Henry, failed to detect it, and suggested that it may have been derived from intermingled slag containing silicate of alumina (Percy, Iron, &c. pp. 183–84).
