Yesterday I did my first volunteer stint at a local archaeology lab. I'm going to work my way through various tasks, learning as I go, and this first one was "Washing."
Basically, the dig team collects and bags artifacts and other markers (such as the residue from fires). These bags are labeled and brought to the lab. Before they can be sorted, identified, and catalogued, they must be washed.
Which entails pretty much what you would think: you carefully dump the contents of a bag onto a plastic tray, then scrub each item free of dirt and grime with a toothbrush before rinsing it and placing it on a screen to dry.
What makes the task interesting - besides the "whee! I'm doing archaeology!" aspect - is the way each kind of object requires a slightly different approach.
Little bits of glass are the easiest; it's obvious when they are clean and when they are not, and minimal scrubbing with a soft toothbrush is required. Chipped stone (as in arrowheads) is the next easiest; it tends to be durable and smooth. Ceramic pieces are also good. For them, you need a stiffer brush than you do for glass, and some pieces are fragile and don't take well to soaking (one kind, officially called "tinware" is called "M&Ms" by the dig crew because of the way its thin glaze can pop free), but they are often interesting to look at. Also interesting, but fiddly, are pipe stems, which need to be cleaned both inside and out, which requires delicate work with pipe cleaner and dental pick.
Plastics and bone tend to be fiddly and sometimes fragile. A simple piece of plastic is easy (though it holds onto dirt more than glass, stone, or ceramic), but the screwcap from a milk bottle was maddening. Things like teeth are able to be scrubbed; softer more fragile pieces are not.
The remaining three categories offer several different forms of aggravation. The first is plaster and brick. Both are soft and if they get too wet, they start to dissolve. This is tricky when they are attached to something hard that needs scrubbing like, say, a piece of sewer tile. Pieces of metal are a mixed bag. On the one hand, you cannot scrub them too forcefully, or bits crumble off. On the other, it sometimes seems like the object is nothing more than a crumbly mixture of iron and soil in the shape of a nail. (The crew call these "cheetos" - another bit of apt food slang.) So they're a pain and unsatisfying, but you also aren't expected to achieve much by washing them. The last are these weird bubbly hunks of something that looks like carbonized tar, which are a form of fire residue. They are tough and can be scrubbed without fear - but they are also full of nooks and crevices that fill up with dirt and provide places for lots of tiny roots to attach.
I finished half a tray, and go back next week.

After lunch I went to work in the ceramic studio. They have a deal where you can rent a cubby and studio time, and if you buy your clay from them, the price of the firing and glaze is included. I've been going in there once a week (though I skipped last week) to play with the clay.
When I first went in, I felt somewhat as to a loss as to what I wanted to make, knowing only that I wanted to play with the clay again. (I have realized that it's been nearly 20 years since I've spent much time in a studio.) I've made a pinch pot, and a little cat, which have been fired. I'm working on a small slab box, and yesterday I threw four bowls. I've finally relaxed about not having an Official Project; I've realized that what I'm doing is, in effect, an exercise in reminding myself of the skills I have or had, so none of these practices pieces are a waste of time and clay.
Yesterday, as I noted, I set down to throw for the first time in years. I've always had a bit of a hang-up about throwing in that I find the first essential step - centering - to be both fiddly and demanding of strength I don't have. I also dislike having to work with an electric wheel - the wheel I learned on as a teenager was a good, old-fashioned kick wheel - because the control over the speed isn't as precise, and the angle between working surface and potter isn't as good. So I've had this irritation about centering, but I decided that since there was no one else in the studio to see me screw up, I might as well give it a try. Plus, I really want some nice symmetrical bowls and cups!
Some of the same old issues surfaced; I still don't have the knack of bracing my forearms against a leg to hold the spinning clay still, nor the hand strength to do it that way. But I did manage well enough to produce three smallish containers. And then I figured out a trick that made the centering, if not easy, much less difficult.
It's not pretty. It involves me hunching over the spinning clay, both elbows wedged into my belly, nose inches from the whirling top wheel. But, hey. It works.
