I work with the geoarchaeology of old stone: quarries, monuments, rock art. And I try to figure out about their weathering and conservation. My domestic services are managed through FABRICA, a registered Norwegian company established with good partners. On this website I publish articles on heritage. For the joy of old stone! Per Storemyr

Burning sea shells to make quicklime once was a great tradition in the North-Atlantic region. In Millstone Park, Hyllestad (W-Norway), we have built two limekilns, reviving old lime burning traditions, involving craftspeople, volunteers and the public. Recently we burnt sea shells to make lime paint and mortar! Read about the experiment in a new poster and web article. Continue reading
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
Last year we built a limekiln at Millstone Park in Hyllestad, Western Norway, reported on this website. The kiln was built in a traditional fashion, following Roman and Medieval principles. Experimental archaeology! After one burn, which gave excellent quicklime, the kiln was, unfortunately, badly damaged. Cracks in the masonry! So we had to rebuild the kiln to be able to produce more quicklime! Over the last few months a team of professional, Norwegian masons and local volunteers, 15 people altogether, has undertaken the task: Just a little more work to be done, and soon we’ll have two(!) limekilns, one big and one small – for producing “historic” quicklime in the years to come. For restoring old stone buildings.
Below, you will find a report of the rebuilding, written in Norwegian. Use Google Translate if you are not familiar with the language. The report is written by me and was first published on the website of Millstone Park (kvernsteinsparken.no) a couple of days ago. I work part-time as an Associate Professor for Millstone Park and I am project leader and responsible for building, rebuilding and running the limekiln. Great combination of craft and theory, experimental archaeology! But I’m also involved, privately and through my company, Archaeology & Conservation Services, as a local volunteer. Building and running a historic limekiln is a very big task, many months of work for many people! And though the Norwegian Directorate for Cultural Heritage is a generous sponsor of the project, voluntary work is indispensable. Thank you all! And here’s the report, with many videos and photos: Continue reading
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
Mange har meninger om frostforvitring på kulturminner, på stein, murverk, puss og mørtel. Men det er få som har dokumentert fenomenet med bilder. Derfor er det mye synsing om «isens ødeleggende kraft». Her presenteres nye fotos av hva som faktisk kan skje når kalkmørtel blir offer for frost. Det dreier seg bl.a. om islinser som dannes og vokser i eksisterende svakhetsplan og sprenger biter bort. Stedet er den nye, «middelalderske» kalkovnen i Kvernsteinsparken i Hyllestad i Ytre Sogn.

Experimental archaeology: Building a “classic”, intermittent limekiln and burning marble at Millstone Park, Hyllestad, Western Norway
It took us about six months: Building a cylindrical limekiln of the classic Roman/Medieval type with local materials only – stone rubble and clay. In June this year, we built the firing chamber and filled the kiln with 2.5 tons of local marble, covered the kiln with clay on a layer of spruce branches and started burning. Five days and five nights with much of the local community involved! Here’s an extended photo story of the project – the first of its kind in Norway. The quicklime (burnt marble) will be tested at Selja medieval monastery and other restoration projects in Norway. Thanks to all paid and volunteers and support from The ruin restoration programme of the Norwegian Directorate for Cultural Heritage, as well as Hyllestad Municipality! The project was carried out by The Norwegian Millstone Centre/The Museums in Sogn og Fjordane County. Continue reading
With a picture – taken today – of a most beautiful little, old quarry in Western Norway, I wish all my clients, partners, colleagues and followers of my website a Happy New Year!
I’ve been up and down Norway many times in 2016: Special thanks to my clients! Those who have actually made the world go round for my company and my family: first of all Archaeological Museum at the University of Stavanger, but also Tromsø University Museum, the Norwegian Directorate for Cultural Heritage and Selje Municipality, Norwegian Institute of Cultural Heritage Research, the Restoration Workshop of Nidaros Cathedral and Akasia Bergen, as well as Statsbygg and Forsvarsbygg.
Also thanks to institutions that I have cooperated much with in 2016, in particular Bergen University Museum, Geological Survey of Norway and The Wadi el-Hudi Expedition (Egypt/US).
The photo above was taken in the afternoon today, on New Year’s Eve. It shows a tiny part of the grand Viking Age and Medieval millstone quarry landscape in Hyllestad. In my world it is the most beautiful quarry in Western Norway, a quarry taken over by a creek in the rainy midwinter season. But no wonder why I think it is a beauty: it is located in my backyard.
Thus, also thanks for 2016 to Norwegian Millstone Centre/The Museums in Sogn og Fjordane County, that are responsible for this largest Viking Age and Medieval quarry landscape in Northern Europe. This is where I work part-time and the reason why my family and I settled at the Atlantic coast a couple of years ago.
All the best for 2017! Continue reading
Menneskene har brutt stein til alle mulige formål siden tidenes morgen. Men hva er et steinbruddlandskap? Hva kan vi si om alle de millioner av steder der folk har tatt ut stein? Fra den tidligste steinalder til i dag? Det var temaet jeg fikk til et foredrag på det 14. Hyllestadseminaret i slutten av april 2016, i regi av Norsk Kvernsteinsenter. Dessuten skulle jeg snakke om hvordan steinbruddlandskap kan formidles. Jeg innså raskt at oppgaven var helt umulig. Continue reading
Det er nesten ingen gamle steinbrudd på UNESCOs verdensarvliste. Det er ikke bra, for steinbruddene var helt sentrale produksjonssteder for verktøy, husgeråd, våpen, boliger, kunst, monumenter – arkitektur – kort sagt en vesentlig del av hva som var viktig i gamle samfunn – og i dag: Store deler av verdens kulturarv er jo basert på brytning av stein. Spørsmålet er: Hvor går veien videre for gamle steinbrudd som verdensarvsteder? Kanskje Norge burde fremme en egen steinbruddsnominasjon? Eller kanskje dette rike landet burde hjelpe mindre bemidlede nasjoner med å få eldgamle steinbrudd inn på verdensarvlisten? Man kunne jo starte i Egypt, landet med den største konsentrasjonen av gamle steinbrudd i verden. Continue reading
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.
