Firmaet mitt er nå del av FABRICA.no / My company is now part of FABRICA.no

Our new website at fabrica.no

See English text below

Enkeltpersonforetaket mitt “Archaeological & Conservation Services” er fra april 2019 del av nyskapningen FABRICA kulturminnetjenester as. Sammen med Morten Stige og Vegard Røhme håper jeg å kunne tilby enda bedre tjenester til kulturminnevernet. Ideen er enkel: Sammen er vi sterkere og mer kompetente! Les om hva vi tilbyr på vår nye nettside.

For eksisterende kunder vil det ikke bli forandringer. Jeg vil jobbe med akkurat de samme temaer som før, men i et felleskap, noe som betyr mer kunnskap ut til kunden. Alle eksisterende avtaler vil bestå uten endringer. Det eneste som vil skje, er at fakturaen til norske kunder etter hvert vil komme fra FABRICA. Nye avtaler vil gjøres med FABRICA, gjennom meg, dvs. i praksis på akkurat samme måte som før. Jeg legger stor vekt på personlig kontakt og oppfølging, og skulle det være spørsmål, så kontakt meg på 95 330 460 eller per.storemyr@hotmail.com.

Utenlandske oppdrag vil fortsatt går gjennom “Archaeological & Conservation Services”. I praksis betyr dette bl.a. feltoppdrag i Egypt. Her er det altså ingen forandringer.

Websiden min www.per-storemyr.net vil bestå. Det vil komme noen små tilpasninger, men siden vil fortsatt være en kunnskapsbase for de ca. 2000 besøkende jeg har i måneden. Jeg kommer fortsatt til å legge ut artikler om «gammel stein» når jeg har tid.

Sammen er vi sterkere i kulturminnevernet!

Partners in FABRICA: Vegard Røhme, Per Storemyr and Morten Stige

My one-man company “Archaeological & Conservation Services” is from April 2019 part of a new company, FABRICA kulturminnetjenester as, registered in Norway. Together with colleagues Morten Stige and Vegard Røhme I’m determined to offer even better cultural heritage services. The idea is simple: We are stronger and more competent together! Read about the new company at www.fabrica.no (still only in Norwegian).

For all my existing clients, there will be no changes. I will work with exactly the same themes as before, and existing agreements will remain. Only that my Norwegian clients from now on will get the invoice from FABRICA. For my foreign clients (outside of Norway), there will be no changes whatsoever. I will continue to serve foreign customers through “Archaeology & Conservation Services”. This especially applies to my work in Egypt.

My website www.per-storemyr.net will remain. There will be some tiny adjustments, but the site will continue to exist as a knowledge-base about “old stone” for my c. 2000 monthly visitors. I will publish articles as time permits.

I value personal contact in my work, and if you have questions, please call me at +47 95 330 460 or write me at per.storemyr@hotmail.com.

Together we are stronger in preserving cultural heritage!

Kinn kirke er ei av våre viktige middelalderkirker. Der langt ute i havgapet, der mytene og fortellingene om Seljemennene og St. Sunnivas flukt fra Irland råder. Men Kinnakirka er mye mer. Det er ei kirke som på eksemplarisk måte viser middelaldersk byggekunst. Hvordan man søkte, og fant, de mest egnede stein i regionen. Stikkordet er veldannet devonsk sandstein brukt som “fake” kvaderstein. En stein som ikke finnes på øya Kinn og som har sin opprinnelse i Den kaledonske fjellkjedes vekst og fall for 400 millioner år siden. Men bruken av steinen har også sin opprinnelse i felleseuropeiske byggetradisjoner i middelalderen. Continue reading

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.

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

The limekiln at Hyllestad, Western Norway: Rebuilding a new, “historic” kiln for burning lime

Nokre av ovnsbyggjarane. Frå venstre: prosjektleiar Per Storemyr, Leif Akse, Terje Berner, Franziska Rüttimann, Jakob Solheim, Chris Pennock, Ann Meeks, George Murphy, Kjell Magnar Myklebust og Bjørn Idland.

Some of the limekiln-builders. From left to right: project leader Per Storemyr, Leif Akse, Terje Berner, Franziska Rüttimann, Jakob Solheim, Chris Pennock, Ann Meeks, George Murphy, Kjell Magnar Myklebust and Bjørn Idland.

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

Historien om et saghus i Gudbrandsdalen: Produksjon av kleberstein som ildfaststein til smelteovner

Rammesag for oppskjæring av store kleberbloker i Saghuset på Sagflaten: Foto: Per Storemyr (2018)

Bergverkshistorien er full av særegne beretninger. Hva med Einar Sagflaten? Han startet som kleberarbeider som 15-åring og holdt det gående i 43 år i et helt spesielt saghus for stein: Det fortsatt velbevarte saghuset på Sagflaten ved Sel i Gudbrandsdalen. Einar drev på i kulda og kleberføyka til helsa sa stopp og saghuset ble flyttet i 1982. Da hadde han skåret tusenvis av kleberblokker som skulle ut på lange reiser verden over, til Bilbao og Calcutta og Marokko. Der skulle blokkene brukes til å lage smelteovner for celluloseindustrien. Det handler om kleber som ildfaststein. Bli med på en reise gjennom enorme forandringer i steinindustrien – i løpet av bare 40 år. Det blir også en svipptur til kleberindustrien USA og ikke minst til de gamle jernverkenes masovner. For også her trengtes det ildfaststein. 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 forms of ice growth: Ice needles, ice whiskers, ice lenses. An entirely different thing than statements suggesting that the 9% expansion taking place when water freezes to ice breaks porous materials apart. Although supported by one case study only, what strikes me is the resemblance between ice growth and a more well-known weathering agent: Salt crystallisation – the growth of salt crystals destroying materials. My observations took place over the last few weeks, in Hyllestad in Western Norway, on the masonry of a copy of a historic lime kiln. Continue reading

The small, Romanesque Gildeskål church is one of the most complete marble churches in Norway. It resides at the magnificent coast along the Atlantic Ocean far up north, in Nordland county. And it is, presumably, the northernmost marble church in the world. Together with Giske church further south, it is part of outstanding, but little known, medieval marble architecture in Norway, of which Nidaros Cathedral in Trondheim, with thousands of marble columns, is the most spectacular example.
