Craft Fair Update

Its been a hectic week of preparation for my run in the Fine Craft and Design Fair at the Arts and Culture Centre in St. John's next week. I've ran into a couple of people who said that they thought the fair was this week. It is, but I won't be there until next week. It runs for 5 days this week and 5 days next week, for a total of 10 days. There are a dozen or more exhibitors attending for the full 10 days and 60 or so exhibitors attending either the first 5 days (Nov 4-8) or the last 5 days (Nov 11-15). You can see the full list of craft producers and the days they'll be attending here.

Elfshot will be there for November 11-15th, and I'll be demonstrating flintknapping on Saturday November 14th for two hours starting at 10AM.

The reason for the move to the Arts and Culture Centre is the Convention Centre downtown kept raising their prices on us. Every year we had to pay more and it was impossible for the Craft Council to break even on the event. There is no comparable sized venue in St. John's. We needed a place with room for 70-100 booths. We picked the Arts and Culture Centre, for a lot of reasons, but the smaller floor space meant that we needed to create two back to back fairs to fit in all the booth holders.

There are some really big benefits to the Arts and Culture Centre for everyone. One is the parking - there are hundreds of free parking spaces, which was a big issue for a lot of people at the downtown location. Since its a public space and so much cheaper for us to rent than the Convention Centre, the admission is free. You can come as often as you want and it won't cost you anything. Although, if you are in the Christmas Spirit, the Craft Council of Newfoundland and Labrador has partnered with the CBC and the Community Food Sharing Association and there will be locations for donating non-perishable food items or cash at the door.

Harpoon Foreshafts and Gelatin Seals

Between the leftover Halloween candy and visions of giant gummy seals I hardly slept at all last night. I've been thinking a lot more about the ballistic gel seal idea.

I think that in order to properly test both barbed and toggling harpoons the gel seal would have to have three layers. Skin, blubber, and meat. I think rawhide would work for the skin layer, and two layers of gel could serve as the blubber and meat layers. The meat layer would be a dense ballistic gel and the blubber layer would be a gel made with more water, so it would be a little squishier. If you aren't squeamish, you can see the layers that make up a seal here: culture camp how to butcher a seal demo.

I've been using Knox Gelatine (its spelled that way on the box) to make the ballistics gel. To make edible gelatin, the recipe is one packet of Knox's for 500 ml of water. I'm using about 700 ml of water and in the first batch I used 2 packets of Knox. This made jello. All it was missing was the sugar and the floating peas and chunks of ham. I remelted the gelatin by floating the tupperware in a sink full of hot water and mixed in a third pack of Knox. The 3 pack-700ml gelatin block is the one I used in these photos. It held together a little better although it still failed (the third picture in the triptych below). It might make an ok fat layer, but I think its still softer than any real animal fat. I'm melting it down again and I'll add a fourth pack. My guess now is that 4 packs of gelatin will make an alright fat layer and that I'll need at least 5 or 6 packs to the same volume of water to make a dense enough muscle layer.



One thing that this avenue of thinking has illustrated for me is the functional difference between the long foreshaft on the barbed harpoon and the short foreshaft on the toggling harpoon. They start to make sense if you think of a seal in three layers, with skin and fat near the surface and meat somewhere deep inside. The toggling harpoon head works in the fat near the skin while the barbed harpoon needs to grip the denser muscle tissue deep inside the animal. The different lengths of the foreshafts would deliver the harpoon heads to the appropriate depths inside the seal.

The harpoon reproductions on the left are two different cultures, and all of the tools made by the Palaeoeskimos were smaller than the Maritime Archaic equivelant, so its kind of like comparing apples and oranges. However, the Maritime Archaic Indians also made toggling harpoons, and the foreshafts for those are much shorter than the foreshafts on the barbed points. One recovered at Port au Choix with the Maritime Archaic toggling harpoon head still attached was only 18 cm long. Out of context, it could have passed for a large Palaeoeskimo foreshaft (the foreshaft in my Palaeoeskimo reproduction is 12 cm long). The Maritime Archaic made both barbed and toggling harpoon heads and they made both long and short foreshafts, which makes sense when you consider where each of these kinds of harpoon heads would work best inside the body of the marine mammals they were hunting.

Maybe an experiment built around foreshaft lengths would be a good excuse for stabbing blocks of ballistic gel with harpoons. I'm thinking about other tests involving barbed versus toggling harpoons and stone endblades versus self-bladed harpoon heads. Thank you everyone for commenting on the last post - keep the ideas coming.

Jewelry and Harpoon Head Ideas

Its a jewelry week here. I'll be focusing on glass, chert, and fibre optic glass. I have bags of points that I keep on hand for emergencies. I don't have a lot of time before the craft fair, so I'll try to avoid starting pieces from scratch and focus on what I already have that is ready to be assembled.

On the other side of the coin, Elfshot is in great shape for artifact reproductions and original knives. I don't usually have this many artifact reproductions on hand so I'm looking forward to seeing how the craft fair display will go together. I have two harpoons ready to go, one is Dorset Palaeoeskimo and the other is a Maritime Archaic Indian style, just waiting for a red ochre application. I put a braided line on the Maritime Archaic harpoon because I liked John's idea so much. The 4 strand round braid takes the relatively thin harp seal leather and turns it into a pliable strong rope. I still wish I could find some good strong bearded seal skin, but the braided line does look nice.

I don't often have extra harpoons around the house either, so I feel like I'd like to do a little extra photography with them. Its especially interesting because they are so different, the Maritime Archaic Harpoon is a self-bladed barbed point while the Dorset Palaeoeskimo harpoon has a stone endblade fitted into a toggling harpoon head. This would be a good opportunity to illustrate the differences in how they work. Thanks to Mythbuster's the internet is full of recipes for homemade ballistics gel. I think I'll make some and stab it. If I have some successful experiments I'll post pictures.

Craft Fair Obsidian

The 2009 Fine Craft and Design Fair at the Arts and Culture Centre in St. John's starts next week. The fair is 10 days long this year with a switch over in booths after five days. I'm participating in the second half of the fair so I have just under 2 weeks prep time left.

I've been working on larger one of a kind pieces, like harpoons, knives and Lost Stone necklaces this week. They aren't the sort of pieces that I like to be working on at the last minute and if something goes wrong I want as much time as possible to fix them. In the next couple of days I'll switch to smaller jewelry. If there are colours or materials that you'd like to see at the fair let me know ASAP and I'll be sure to have some on hand.

Here's a peak at the knives while the sinew is drying and the Lost Stone necklaces before they are strung. I've had these knife blades around since at least last spring, but I just got around to making handles for them this week. There are a couple maple handles in there from some left over hardwood flooring at Lori's parent's cabin, a couple pieces of yew from this summer's bows and a couple moose antler handles. I don't think I've used any of these materials in knife handles before so the fair will be a chance to see which materials and styles appeal to people. I like the moose antler tines more than I was expecting.

The Lost Stone necklaces are different every time. It looks like I'll only have 6 ready for the fair, so if they appeal to you come see me early between November 11-15th. Parking and Admission are free this year so you can come check out the show as many times as you'd like!

Ivvavik, Aulavik, and Tuktut Nogait Recap

This is the final post on the Parks Canada project and then I'll stop talking about it. It went on a few weeks longer than I expected and I blame a lot of that on the weather slowing down some of the final drying stages. The photos show the original Inuvialuit artifacts alongside the reproductions. These aren't casts - they are 1:1 reproductions made in the original materials; wood for wood, antler for antler, tin for tin, etc. All of the artifacts have Parks Canada numbers attached to them somewhere. I marked or engraved a "TR" in the same location on all of the reproductions to help distinguish them from the originals. I have one last meeting in at The Rooms this morning. Elaine Anton has been a tremendous help arranging the shipping and storage of the artifacts while I've been working on them. Today she assesses the condition of the artifacts to ensure that there was no deterioration of their condition over the summer and we'll package everything up for FedEx to pick up. Later today the artifacts go back to the conservation lab in Winnipeg and the reproductions head to the Parks Canada Office in Inuvik.

Final Parks Reproductions

Here's a look at the last of the Inuvialuit artifact reproductions done for Parks Canada in Inuvik. I'll post side by side group shots of artifacts and reproductions from each of the three parks in a future post.

Tuktut Nogait Bow: Tuktut Nogait National Park. This reproduction was great fun to do and although this isn't a functional bow I learned a lot about bow-making from this artifact and I still plan to make a working copy of this bow over the winter. Its made from yew. Its in two parts with a V or fishtail splice through the shorter, lower limb. Its very light and thin limbed compared to a lot of other cable backed bows that I've come across.
In each photo the artifact is shown closest to the ruler, with the reproduction on the opposite side. In the first two photos the pieces are shown belly side up, and in the third the bow's back is facing up. I've already talked a lot about making this piece in earlier posts. Finishing involved a lot of wire brushing to bring out the wood grain and match the weathered texture. The colour and texture matching came from rock dust, sawdust, water based stains, red ochre, charcoal, and burnt umber. This is a piece that will benefit from handling. The more wear and tear the reproduction gets the better it will look.



Slate Knife: Ivvavik National Park. The artifact is in the middle. This knife is a little unusual in that its chipped slate instead of ground slate. Ground slate knives may be roughly shaped by flaking, but slate isn't a very good stone for knapping. Usually slate is finished by grinding and polishing. The handle portion of the original artifact is almost completely unworked, so the chipped blade may have been a quick attempt to turn a knife shaped rock into a real knife. Slate is a pretty soft stone that likes to break apart along flat planes, which is why its so difficult to knap. Under the sawdust and woodshavings in in my workshop there are at least a dozen failed attempts at making these two knives. I finally had to go with a slate that isn't as perfect a colour match as what I was hoping, but the best look alike slate I had found refused to stay in one piece. These reproductions will be much more durable, I feel much more confident sending them off knowing that they will be able to hold up to the sort of handling they are intended for.

Antler Handle: Tuktut Nogait National Park. This is an antler socket that was extremely deteriorated. It was a challenge to reproduce because I wanted to match the flakey weathered look of the original, but at the same time have something that wouldn't fall apart being handled. There's not much point in making a reproduction of a fragile artifact that is more fragile than the original. To match the texture and colours of the piece I used layers and layers of sawdust, antler dust, whalebone shaving, and rock dust. In between the layers I'd brush with a wire brush to create the pitting and texture of the disintegrating antler. There was plenty of blowtorch in there as well.
In both photos the artifact is on the left and the reproduction is on the right.

Kayak Rib: Tuktut Nogait National Park. This was that bent wood piece that was giving me so much trouble. I finally got it to hold its shape by building a stand for it. As long as its stored in its stand there's no danger of it straightening out again. There is an interesting patch of green staining on one end which I used verdigris from the copper experiments earlier in the summer to match. It gave a very good match - I wouldn't be at all surprised if the staining on the artifact came from contact with copper.
I keep referring to this as a kayak rib, because that's what I think it is. I don't have any evidence for that other than the fact that its shaped an awful lot like a kayak rib and I'm not sure what else it might have been used for.
In both photos the artifact is closest to the ruler. I'm going to try to be more consistent in the future with my photography or artifacts and reproductions, with artifacts always below or to the left of the reproductions.

Fort Garry Tobacco Tin and Quartzite, Again, Finally

I ate about six pounds of jujubes, gummy worms, and gum balls yesterday so it must have been a good birthday. Lori also topped up my chocolate covered espresso beans to help me wake up in the mornings, which is good because six pounds of jellied sugar rolling around your guts sure doesn't make you want to pop out of bed the next day. I also got a bunch of new clothes including this shirt.

I had hoped that yesterday would be the last day working on the Parks contract, but after comparing the final reproductions to the artifacts and talking to a conservator friend who works at The Rooms, I realized that almost everything was missing an important brown colour. Its all done, but the last set of artifacts could really use some more Burnt Umber, so on the way home I stopped at MF Kelly and picked up some pastel and charcoal sticks to grind up and dust on. I have one more trip today to confirm that Burnt Umber made them good and then thats it. It'll just be packing and shipping after that.

Fort Garry Tobacco Tin: Aulavik National Park. The reproduction is above the original in both photos. This was a new sort of reproduction for me so it had a bit of a learning curve. I've talked a little about the history of the tin and my approach to reproducing it in previous posts. The words that you can't quite read say "FORT GARRY SMOKING TOBACCO". Aging the paint and adding the rust were the most challenging aspects of this project. I wound up using white washes over areas of the paint to create the sun bleached look of the paint. Without the white wash the paint colours and contrast were a little too sharp. The rust/paint boundaries were still a little sharp. In the artifact there is a kind of rusty halo that creaps out around the exposed rusted metal into the adjacent paint. On my reproduction the paint/metal boundaries were too sharp until I added a final red ochre wash around the rust patches to create the fuzzy boundaries and depth that I needed.

It was possible to have a lot more control over the rust than I'd imagined. The paint did its job and prevented the muriatic acid from rusting anywhere that it touched. To guide the shape fo the rust pattern all Ihad to do was scrape off the paint in the areas that I wanted to rust. Once the muriatic acid had rusted an area I could tweak the colour by adding water, sunlight and a quick drying environment to give me brighter reds and oranges. Dabbing a bit of tea on the rust would turn it black from the tannins. The piece was constantly evolving and responding to the temperature and air around it, on dry days it would be more orange and on damp days it would be more black. To try and stabilize it at the point I wanted it, I sprayed on a clear varnish. I needed that clear finish to match the gloss of the original tin and blocking out the air should prevent future changes in the rust colour.

Quartzite Scraper: Tuktut Nogait National Park. The artifact is on the left and the reproduction is on the right. This is the last piece of quartzite in this contract. I don't know how many versions of this piece I made over the summer, but I destroyed most of the quartzite that Jack Cresson gave me trying to get this piece out. Basically, its a very short hard hammer flake removed from the dish shaped flake scar of a previous hard hammer flake. Its part of a cone made on the negative space made by a cone. Its another one of those really simple and really difficult pieces to make. The original artifact would have taken less than 20 seconds to make by hitting one rock with another rock twice. But trying to match those exact conditions a few hundred years later is like trying to copy a snowflake. Like I said on Wednesday, the simpler something is the harder it is to reproduce.
