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

Kvernsteinsbruddene i Hyllestad: en historie i tre akter
Lihesten er selve symbolet på Hyllestad. Majestetisk ruver den over en liten kommune med et av Norges største kulturminner: kvernsteinsbruddene. Herfra ble det skipet ut håndkverner og vasskverner til store deler av Nord-Europa i vikingtid og middelalder. Men Lihesten er også et symbol på den dramatiske geologihistorien som gjorde kvernsteinsproduksjonen mulig. I denne artikkelen får du hele historien i tre akter; den første akten startet for flere hundre millioner år siden, den siste foregår nå – i friluftsmuseet Kvernsteinsparken under det ruvende fjellet.

Beautiful Neolithic and Iron Age querns from Norway. On the history of grinding grain
The basement of the Archaeological Museum at Stavanger University holds the largest collection of grinding stones and querns found at archaeological excavations in of Norway. Dating from the Neolithic to the Middle Ages, they show the development from saddle querns to standardised rotary hand querns. The finest querns are on display in the museum, and together with the magazine objects they particularly show the early development of the rotary hand quern in Norway: From 1800 year-old, very diverse specimens to the standardised, transportable rotary quern that we know so well from the Viking Age and later, and which became an important commercial trade good.

The rhyolite quarries at Bømlo in Norway: Traces of firesetting in the Neolithic
A couple of days ago I climbed the mountain Siggjo in Western Norway together with my family. Siggjo is renowned for its deposits of the volcanic stone rhyolite that was heavily used for arrow heads and other tools from c. 4000 to 2500 BC in the Norwegian Neolithic. Finally I got to see the great traces of firesetting that are present in these hilltop quarries! The traces were interpreted by archaeologist Sigmund Alsaker almost 30 years ago, and we relied on them as an important reference when conducting experiments with firesetting in the North-Norwegian Mesolithic Melsvik chert quarries two years ago – experiments that I have previously reported in my blog.

On the origin of Roman concrete
You mix burnt lime, volcanic ash and sand/gravel. Then you have the famed concrete that made the Romans able to build the Pantheon cupola, or to make underwater constructions, like big harbours. And without Roman concrete, we may not have had our modern concrete, based on Portland cement, enabling us to build ever bigger, higher and deeper. But how was Roman concrete discovered?

Nidarosdomen og forvitring – sett fra 17 år tilbake i tid
Ganske tilfeldig kom jeg over en utgammel tekst om Nidarosdomen og forvitring her forleden. Det viste seg snart at det var en omtale av min egen doktoravhandling om temaet fra 1998; stødig ført i pennen av Hans Georg Jürgens og publisert i Universitetsavisa i Trondheim. Så leste jeg gjennom. Og fant ut at det meste har aktualitet den dag i dag. For om man googler “Nidarosdomen og forvitring”, så dukker det fortsatt opp helt tullete skremselsbilder om gigantisk luftforurensning som tærer på nasjonal-helligdommen. Nei, forvitringen på Nidarosdomen er nok mer kompleks enn som så.
Så jeg tillater meg å sitereden 17 år gamle omtalen til Hans Georg Jürgens i sin helhet. Den har tittelen:
“Nidarosdomen skranter… Continue reading

Palaeolithic rock art at risk: New discoveries in Wadi Abu Subeira, Upper Egypt
The number of discovered Late Palaeolithic rock art sites in Wadi Abu Subeira (Upper Egypt) is ever increasing, now with finds also outside of the wadi, at el-Aqba el-Saghira. Archaeologist Adel Kelany of the Ministry of Antiquites (MAS) in Aswan has just published an overview paper, now listing ten sites, all with numerous panels. The largest site has a much as a hundred ones. As previously noted on this blog, this world-class rock art is under heavy pressure from modern mining, though efforts to protect the sites have shown some effect recently. Continue reading
