In this context you may compare with
Marie-Luise HILLEBRECHT, Holzkohle als Informationsquelle der
Archaeometallurgie. Ergebnisse aus Untersuchungen im Bereich der
Harzregion.
(Charcoal as a source of information in archaeometallurgy. Results of
reseach in the Harz region - Germany). In: Symposion Archaeometallurgie
von Kupfer und Eisen in Westeuropa. Mainz, 12.-15.09.1986. Jahrbuch RGZM
35 (1988) - Inga Serning volume, 495-505.
There are still several copies of the Inga-Serning-Volume available.
