“…Different Sn isotope d values have been presented in the literature to date. Remaining consistent with Balliana et al (2013), Yamazaki et al (2013) and Mason et al (2016), the d 120 Sn/ 116 Sn and d 124 Sn/ 116 Sn values are presented based on Equation (1)…”

“…Thus, Sn isotope values are corrected using Sb and also bracketed by calibrators as discussed in Mason et al . (). Since no international isotope reference material exists for either element, NIST SRM 3161a (lot number 07033) was used for Sn and high‐purity ICP‐MS Sb reference material 10 2–3 (10 μg ml −1 in 2% nitric and trace HF) was used as a dopant.…”

“…Equally important, the reduction of the data without Sb correction produces larger uncertainty for the variation of the calibrator through the measurement session (on the order of 0.3‰ for d 124 Sn/ 116 Sn rather than the 0.08‰ reported below). Thus, Sn isotope values are corrected using Sb and also bracketed by calibrators as discussed in Mason et al (2016).

“…Tin isotope geochemistry has started to gain momentum as an analytical approach due to documentation of measurable differences within groups of bronze artefacts and between geographically distinct mining camps (Haustein et al 2010, Nickel et al 2012, Balliana et al 2013, Yamazaki et al 2014, Mason et al 2016. With ten Sn isotopes, there is a large mass range to analyse for this metal.…”

Increased interest in the fractionation of Sn isotopes has led to the development of several techniques for preparing cassiterite (SnO2, the primary ore of Sn) for isotopic analysis. Two distinct methods have been applied in recent isotopic studies of cassiterite: (a) reduction to tin metal with potassium cyanide (KCN) at high temperature (800 °C), with subsequent dissolution in HCl, and (b) reduction to a Sn solution with hydriodic acid (HI) at low temperature (100 °C). This study compares the effectiveness and accuracy of these two methods and contributes additional methodological details. The KCN method consistently yielded more Sn (> 70% in comparison with < 5%), does not appear to fractionate Sn isotopes at high temperatures over a 2‐hour period and produced consistent Sn isotope values at flux mass ratios of ≥ 4:1 (flux to mineral) with a minimum reduction time of 40 min. By means of a distillation experiment, it was demonstrated that HI could volatilise Sn, explaining the consistently low yields by this method. Furthermore, the distillation generated Sn vapour, which is up to 0.38‰ per mass unit different from the starting material, the largest induced Sn fractionation reported to date. Accordingly, the HI method is not recommended for cassiterite preparation for Sn isotopic analysis.
