Blog Action Day 2009: Climate change

Blog Action Day is an annual event held every October 15 that unites the world’s bloggers in posting about the same issue on the same day with the aim of sparking discussion around an issue of global importance.

I remember as a child going to Man and His World (the site for Expo ’67, the 1967 International and Universal Exposition) in Montreal, and visiting all the international pavillions. I remember in particular the American Pavillion and always seemed to gravitate to it whenever we visited.  It was a huge, clear panelled geodesic dome structure that really stood out among the rest of the buildings.  It being so long ago,   I admit, memories are a little vague, but I have fleeting images of the experience such as the sun blaring through the glass.. vegetation lining paths on the ground level.. futuristic bits of art and culture.. stairs going up to a different level where screening rooms with films about acid rain, air & water pollution, the depletion of the ozone layer, etc. , etc, were shown.

Biosphere Montreal Expo 67I know I was young, but it obviously left an impression on me, because I still remember it.  The warning was clear that we should be very conscientious of how we live, how we treat the environment, and take care of the world around us, or the fragile natural world as we know it will be lost for future generations.

Despite what certain special interest groups tell us and want us what to believe, I think its naive to think that the climate change is not real and that we can keep on the way we have been.   Human activities might not be the only reason why global warming is occurring, but it is occurring nonetheless. The exponential growth of human populations and industrialization has had a huge impact on the ecosystem and has undoubtedly helped to expedite climate change.  We’ve known about it for a long time but denying a problem does not make it go away.   On that note…

Over the last few days, I’ve tried to think of how life at our studio might relate to the global warming. Thinking back, most of the changes we have implemented in the past few years were for economic reasons, but they have spinoff benefits that are releva for the  environment as well.  In the past 9 or so years, the cost of propane (we glaze fire in a gas kiln) has more than doubled and the cost of raw materials and shipping has gone up by at least 1/3.  Working smarter and more efficiently , obviously, has become all that more of a priority.

THE KILN

Nitride Bonded ShelvesWhen I think of climate change and how it relates to pottery, what first comes to mind is my kiln which uses propane.  A fuel burning anything is a potential area of concern when you are trying to reduce your carbon footprint.  One thing working in our favor is that  our studio and kiln are located on a treed 5 acre plot of land.  A friend yesterday reminded me as well that propane does burn more efficiently and releases less particulates and pollutants into the air than, say, a wood kiln or even a salt kiln.

So working with what we have, we have tried to make some changes to help it fire more efficiently and use less fuel.  A big change we made about a year ago was getting some of those new nitride bonded silicon carbide shelves which are much thinner (and lighter) than regular kiln shelves and take require less energy to heat up. (When you fire a kiln, you heat everything in the kiln.. the pots, the shelves, the posts… everything. Anything extra you have means that much more energy consumed.)  So anyways, we did that and replaced the flat top with an arch and I was delighted to discover that the firing took a fraction of the propane it did previously.  Something else that we just did this last firing is reduce the pressure at the regulator on the propane tank. Again, much less propane was used. Brilliant. More firings for less and what fuel we did use what burned that much more efficiently.

NATIVE CLAY

Like propane and natural gas, the cost of raw materials has shot up.  Thankfully we dig most of the clay we use locally. We do this for a number of reasons. Besides the fact that it is very responsive and throws beautifully, it being so readily available and so close to the studio definitely works in our favor. Since we process it ourselves, it is a little cheaper plus we don’t have the additional expense of shipping it down from places like Ohio, Atlanta, California, and some other such places where clay is commercially processed and distributed from.  The environmental impact?  Well, one benefit is there is one less truck on the road and therefore less emissions released into the atmosphere.

OTHER THINGS

We usually have to travel away to do art shows and fairs, so for a number of reasons, we’ve lightened up the weight of our show display so when we do have to travel, its a lighter load and hopefully less wear on the vehicle, less gas, and less emissions.

Shows, Quality not Quantity –  What with the economy, rising show fees and travel expenses,  and the uncertainty of shows, like  many craftspeople,  we have been forced to be a lot more selective about where we go and what shows we do. Consequently that often means travelling less and sticking closer to home.  The internet has also made promotion to a broader audience without travel possible.

At home, I am trying to make changes as well. I switched (mostly out of necessity) from a large SUV to a Toyota Corolla which helps consumption, and switched out all my light bulbs for flourescents or compact florescents bulbs. My gasoline and electric bills have both gone down considerably as a result.  There’s always room for improvement though. I started the summer with plans for a big vegetable garden, but this year with things that come up, as they seem to do, the more invasive weeds just took over. But there is always next year, when I hope to have better luck with planting in raised beds.

So no matter what your lifestyle or how small your operation is, changes to our lifestyle and how we work are possible. Even small changes can have a positive effect on the environment.

Blog Action Day October 15

Bloggers Unite - Blog Action Day

Today is Blog Action Day when blogs everywhere talk about one thing: the environment.

Potters tend to have a reputation for being frugal. Some stems from necessity, some stems out of principle. I started thinking about ways in which we here at the studio try to make a difference to the environment and recycle:

– Building: recycled wood & windows in building studio (reclaimed lots of waste wood from hurricanes which would otherwise be taken to landfill or burned).
– Plastics: We recycle grocery bags & use them for shows (people don’t mind when you tell them it is for the environment) as well as dry cleaning plastic which works perfect for covering pots & protecting controlling how they dry
– Paper: Newspaper and newspaper roll ends are used in the studio for a multitude of uses. Also excellent for packing pots away for/at shows
– Metal: We bought a can crusher and while they don’t pick up recycled items here, we take our tin/aluminum cans to the recycle depot when we are in town.
– Appliances: We have two defunct refrigerators & freezers make excellent damp cupboards and places to keep moist clay.
– Old Machinery: our clay mixers are 2 recycled old machines: one is made from an old WWII anti-aircraft gun and the other a 1915 dough mixer.
– Waste wood & pine needles: We get scrap wood cast offs from the local wood mill and use them to fire the wood kiln. Wood and pine needles burn much more efficiently and with less smoke at the temperatures we fire the kiln to, than it would in a burn pile.
– Cast offs: We use cast-off bisque ware (cracked and unusable) in holes in our driveway, and try to use as many of the glazed cast-offs as bird feeders, planters, dog bowls, etc.. Lots of other shards go to a friend who does mosaics. (We have also used waste oyster shells from the local fishery to fill holes in the driveway – smells a bit at first, but definitely organic)
– Our clay: Now that our clay mixer is operational again, we try to pay extra attention these days to recycle all of our scrap clay into a new batch of mixed clay and make it go as far as possible. A lot of the clay we use, we dig ourselves. The white and bubble gum colored clay that we like to use is considered waste clay to contractors (not good for road base) and they are quite happy if we cart as much as we like off.
– Organic Gardening: We try our best to garden as organically as we can. We have several neighbors with horses that are glad to part with their more than ample supply of muck.
– Commuting: Our little chunk of land houses both where we live and the studio, so thankfully I don’ t have to commute anywhere (except to shows, wholesale customers, and some of my suppliers, of course).
With a group of like-minded artists, we also started a small artist collective to hopefully open up more marketing opportunities closer to home and cut back on travel. Less traveling not only saves us expense, time, and wear and tear on our vehicles (and us) but also means less fuel consumed and less impact on the environment.

Coming from away, I couldn’t help but notice the absence of things such as public transit for commuters and carpooling lanes when I first got down here. SUVs are the vehicle of choice it seems here and its not uncommon to see a Hummer or 2 cruising up the road. No attention to carbon emissions on old vehicles either. Big cars, big boats and often big inefficient houses too. How do permits get granted to construct on valuable wetland? Always has baffled me how a place with so much sunshine has so few people taking advantage or even the slight bit knowledgeable of solar power. Welcome to the Alabama Coast. Consuming with very little thought of conservation. You used to be able to see to the bottom of Mobile Bay not 50 years ago, apparently. Not now though. Pollution from industry-friendly Mobile and other places upstream have unfortunately taken its toll. Its a pity.

Southerners are known to be resistant to change but hopefully they will sit up and take notice before it is too late.
