"and the use of etching to bring the inscription out in white against the ground of the stone."
Remarks
This entry refers to the white colorant produced by etching on hardstone amulets and seal rings (primarily carnelian and chalcedony) acquired by Sir Hans Sloane from 17th-century Iran, specifically Isfahan (p. 277). The text notes that these objects feature predominantly Qur'anic texts, sometimes in gulzār script (ornamentation inside script contours), where etching brings the inscription out in white against the stone ground (p. 277). Footnote 6 identifies specific museum samples (e.g., A14 to A114), including dated examples such as A110 (1666-1667) and A114 (1659-1670) (p. 277).
