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. My domestic services are managed through FABRICA, a registered Norwegian company established with good partners. On this website I publish articles on many aspects of cultural heritage. For the joy of old stone! Per Storemyr

Novel micro-images of lime mortar destruction by frost weathering
Frost is here again and thus weak building materials are at risk, for example traditional lime mortars applied during the last summer season. Over the last few days I was able to observe frost heaving in a lime mortar that has not properly hardened/carbonised due to recent rainy and moist weather. As far as I know, no one has previously documented such ice crystal growth, on a micro-scale. The phenomenon is akin to frost heaving in a soil profile: The force of growing ice whiskers lifting the uppermost parts of the soil. Continue reading
Taken by the frost! The beauty and destructive force of ice growth on masonry
After 29 years of working with weathering of cultural heritage, I have finally seen it “live”: How the force of ice can destroy plaster on stonework. It is more diverse than I though. A complex and fascinating world of beautiful … Continue reading
