SLAM PROJECT 2016: Oil and Timber Section

May 5, 2016

Hi Folks!

It has been more than a year since I last posted, and it would be an understatement to say we are working hard. SO much has happened in the past year! I promised myself I’d keep this one short and just get blogging again, so here is a glimpse of conservation from the Oil and Timber Section we recently installed. YES installed, Opening Day is June 6!


How about this gorgeous chainsaw? Gotta start with an image of Alaska State Museum registrar Andrew Washburn, we’ve been with the artifacts through the whole process and keeping track of the info at breakneck pace. Documentation!!! And really interesting conversations about the strangeness of the out-of-context museum world and what it means for artifact interpretation. In conservation, we have been endeavoring to make industrial objects look reasonably cared for without removing evidence of their useful life. Andrew’s pose captures our discussion about which way the blade faces.


Iron! Here we have a couple of boom chains. The blacker one was treated with OSPHO and the lighter one got a tannic acid treatment. Most of the iron that needed help from the collection got tannic acid and stayed brownish. The brown boom chain was the one selected for exhibition. Incidentally, there were some prop desk legs also treated with OSPHO…they accidentally got wet and a tough white substance showed up on the surface. So difficult to remove! Anyone have experience with that white crust? In general, I wouldn’t OSPHO a museum object but if a blackish appearance is desired a controlled phosphoric acid like OSPHO does the trick. If the white crust had happened on a museum object, that would have been a disaster.



A giant round of spruce. For many many years this was an exhibit prop in the old museum and treated as such. When I came on staff in 2006, it was strapped to the basement wall and only recently been added to the permanent collection. This sturdy iron support had been added years ago to support a large crack. Note all the disfiguring drips.


Most invasive treatment of my life: I took a Festool sander to the face of this spruce round to remove severe staining. I’ll spare you the long in-house decision making process that made that choice even possible, but suffice to say I am in love with Festool now. When the spruce round had been an exhibit prop, there were also large holes drilled to mark certain rings as a timeline. Paintings conservator Gwen Manthey is shown here filling and inpainting those holes. There were four holes, but I dare you to find them now!


Here is the jacket Click Bishop wore back in his days working on the oil pipeline. Yes, that Click Bishop, the Alaska State Senator. There are pants and hat with this outfit too. Here is an image of humidifying the pocket flaps so they would lay flat when the mannequin was dressed.
