When I first started throwing I didn't understand how to recycle clay. So It piled up. After two years and about 200 lbs. of clay to recycle, I tackled it. I have recycling down. When I unloaded the kiln last week several pieces had tiny pieces of metal sticking out of them. I decided to re sieve my glazes. They are in the garage, something must of fallen in. Then on Monday I was trimming. I usually trim very soft, leather hard at the hardest. Well, by the time I got to the last pot in the stack it was pretty dry. While trimming my tool broke. Now I don't have very good eye sight, even with glasses. I'm looking closely at my tool and can see it had worn down to paper thin before it broke. It was a cheap tool, but my favorite. This morning, I am throwing with some of my recycled clay. Every ball had bits of metal in it. I am near tears. I have about 50 lbs of clay I just recycled, wedged, weighed and balled for throwing. I think I need to throw it all away. I don't mind picking the bits out if I cross them when throwing. But if I miss a piece and it shows through the glaze it won't look good. If your still reading, thanks for listening to my rant.
