Erik van der Spek, warden on Texel island in the Netherlands, writes on his blog about archaeological research at the Bleekerij, where a bleaching business used to be; now: an open spot in the forest in the west of the island.
One of the finds there was a silver hairpin from the eighteenth century. Silversmith Reiner Rijnalda (1699-1771) turned out to have made it. He was born in Friesland, but did most of his work in Haarlem. His Texel hairpin was from 1737.
