Welcome!
I work with the geoarchaeology of old stone: quarries, monuments, rock art. And I try to figure out about their weathering, and conservation using traditional crafts. I also burn lime the traditional way. Many of my domestic services are managed through FABRICA, a registered Norwegian company established with good partners. On this website I publish articles on geology and cultural heritage. For the joy of old stone! Per Storemyr

Good stone doesn’t change its location!
There have been few new posts on my blog recently. But there is a very good reason for this apparent laziness, since I’m now writing a book about stone. Or, to be more correct, a book about the cultural history … Continue reading

“Steinriket Bømlo”: Nettsted om steinbrytning i 10.000 år
Her forleden kom jeg over et særs interessant nettsted, nemlig “Steinriket Bømlo” som forteller historien om utnyttelsen av stein på denne ytterst steinrike øya – ytterst i havgapet på Vestlandet. Naturligvis står to av Norges flotteste steinalderlokaliteter i forgrunnen: Øksebruddet på Hespriholmen og pilespissbruddet på Siggjo. Continue reading

De gamle jerngruvene i Neskilen ved Arendal
Neskilen var fra slutten av 1600-tallet et av de viktigste jerngruveområdene i Norge, stort i Norge og stort i “Arendalsfeltet”.

Her var det drift i 200 år fra slutten av 1600-tallet – og her lekte vi som barn ved dype gruveåpninger… Continue reading

Experimental archaeology: The traditional way of quarrying soapstone
Experimental archaeology in old building stone quarries is a rare activity. But not so for Norwegian stone carver Eva Stavsøien. She asked herself how soapstone was extracted in the Middle Ages. Bringing handmade pickaxes, she went to an abandoned quarry … Continue reading

Stone weathering at the westernmost coast of Norway
As probably one of only very few monuments globally, the ruined Selja medieval abbey off the westernmost coast of Norway is built from a metamorphic olivine stone (dunite) rich in talc. The combination of a hard olivine matrix and soft … Continue reading
