Chronometric studies of charcoal production remains are largely based on 14C‐dating of associated charcoal. Owing to intrinsic limitations, however, this method provides no meaningful time resolution for post‐1650 CE features. We investigate the potential of optically stimulated luminescence (OSL) dating of heated sandy sediments as an alternative and complementary tool for dating charcoal kiln remains. Seven samples from five relic charcoal kilns and 11 complementary samples from the underlying sandy substrate are used. Through a range of procedural tests, we demonstrate that the single‐aliquot, regenerative‐dose procedure in combination with OSL signals from quartz allows determining equivalent doses both accurately and precisely. For four of the five investigated kilns, OSL ages are consistent with independent age information from 14C‐dating and written sources. Especially for post‐1650 CE features, the precision can be significantly better than that of 14C‐dating, and we highlight the potential of OSL dating for distinguishing, relatively, between charcoal production phases with an unprecedented time resolution. We conclude that the approach is a promising alternative to 14C. [ABSTRACT FROM AUTHOR]

A heavy and impressive chest — part of the museum collection of the city of Antwerp — served as a strongbox to securely store the city's historical documents, including citizen privileges, public liberties, and responsibilities. A recent dendrochronological survey revealed that the tree-ring pattern of the lid dates to 1005–1294 CE, suggesting a felling date early in the 14th century. The Silver fir wood originated from the Vosges mountains in France, and hence was transported to the city of Antwerp that had already developed as an important trade centre along river Scheldt by the 13th century. The tree-ring pattern of the bottom plank could not be measured, but the presence of caulking material in some large cracks and metal clamps (sintels) revealed that this repurposed timber must have originated from a medieval ship. The archaeobotanical analysis of the mosses used as caulking material and of the pollen trapped in these mosses points toward two different locations where the ship was repaired, with at least one location outside the Low Countries. During the examination, a collection of wooden boxes stored inside the chest drew the attention. It was unclear whether the collection of boxes had any connection with the original content in the chest. Tree-ring dating on these wooden boxes made of oak and beech revealed their 14th to 16th century dating. Furthermore, inscriptions proved their relationship with historical documents. The combined dendrochronological, archaeobotanical, and historical examination demonstrates that this medieval chest was a privileged spectator of the city's turbulent history. [ABSTRACT FROM AUTHOR]
