Clay and consequences

Hello everybody

I could do with your advice and opinion on something personal that's happening with me that relates to this group. Last October I was diagnosed with mild emphysema/COPD. I used to smoke a very little bit in my twenties (I'm now 61). I was also brought up in a smoking household, so I can't pin down just one cause from then.

I suspect that a more significant and maybe more likely cause is that fact that I've worked with clay since I was 12, going on for 50 years now. Having to do the sums makes me feel just ancient :-(( Years ago there weren't the knowledge/warnings that clay and ceramic dusts could give long term problems with lungs. Were there? Clouds of particles from so many sources - plaster, sanding dry work, metal oxides etc, mixing glazes, using onglaze and underglaze colours - the list goes on and on and on. I'm going to have to use masks, take precautions and listen to good advice from now on - something that the group might come up with to help me and others.

The diagnosis of emphysema just stopped me in my tracks. I'm only getting back to work now after several months of being down in the dumps. My husband has been very supportive, as have friends and family. Still, when it comes down to it, I'm on my own with this.

I'm not after the sympathy vote at all. But, I do wonder if it is worth raising the health risk problems in view of where I am now? Young folks think that they are immortal and invulnerable but perhaps putting up a warning might be a good idea? Perhaps it's a warning for us all - I was ignorant of the risk of dust and particles for years and simply didn't take all the care that obviously I should and could have done. But then I didn't realise and wasn't warned about the long term consequences all those years ago.

I'm feeling pretty good at the moment and plan on going back into the workshop on Sunday morning at around 10.00 am. I'll let you know how I get along.

Thanks for being there folks.

I am not snipping this down because I think it is a very important message and wish it were one we all talked about more.

It is so easy to think that nothing can happen to us - it always happens to the other guy. I came very close to losing a hand because of that mind set. I also think it important that it is a regular topic of discussion because new potters are constantly coming into the field who have no idea that silica can be as dangerous as asbestos and silica is in just about all materials that we work with (clay, flint, feldspars, etc.). A studio should always be cleaned with water and never dry swept. When mixing up glazes or clay it should be done with a mask and you and your clothes should be washed afterwards. The fine dust of silica can stay in the air for days - spray the area with a mister after playing with materials.

Nicotine smoke and fine dust particles interact to be a far greater danger than either alone and second hand smoke is actually worse than what smokers inhale.

Yes, we all know potters and smokers who have lived to a ripe old age but they are not the norm. I like potters - they to me are a special breed of people. I want to see them all live well and live long.

Thanks for your posting, Susie. I just finished setting up my home studio and am a novice potter. I will try to think of your post every time I start to decide that it's just too hot or uncomfortable to wear the mask/gloves.

Not trying to be picky here, just want to make clear to any clay newbies that "mask" is *not* one of those little disposable "dust masks" they sell in the paint aisle for a buck or two. It should be what they typically call a "respirator" that covers the bottom half of your face with an air-tight seal. These have replaceable filter cartridges rated for various substances. If you buy the unit at your local hardware store, it will probably come with "Organic vapor/P95" for paint and pesticides. This is really a 2-stage unit: The vapor cartridge is the bulky part closest to your face, which is typically removable via a twist-lock. You don't care too much about this part for pottery work. Just leave it as-is.

The "P95" is a fuzzy white particulate filter pad that goes over the cartridge, usually with some sort of simple snap arrangement. P95 means it is rated to remove 95% of the particulates bigger than

0.3 micron ("fume sized" particles). While that is orders of magnitude better than a disposable dust mask (those *always* leak air around the edges), it is recommended that you get a P100 replacement filter. These remove 99.97% and are also called "HEPA" for High Efficiency Particulate Air filters. As far as I know they are always pink, not white. (There are also apparently thinner/chaper N100 and R100 versions that need replacing more often, but I've never seen them.) Replacement P100 pads are around $5.00 per pair from on-line suppliers.

The main thing with a respirator is that it *must* have an air-tight seal around your face, so that all the air you breathe in comes through the filters. That requires a soft rubber construction with a very flexible lip or edge. When you buy a respirator, the instructions explain how to test for a good seal. Some designs may work better than others with your particular face shape, especially for those with beards. If you don't have a good seal, you don't have a respirator... take it back and try again! (Maybe you could try on a friend's ahead of time, to see if that model is right for you... someone who doesn't mind sharing "cooties" with you!)

Thank you Bob - I just learned a valuable lesson - this will go in my save file and I will make a trip to the hardware store tomorrow. Donna
