Sorry your clay got contaminated Chantay
Metal in recycled clay is a problem. My sad story is that I do metalworking in the same studio as where I throw clay. I was noticing ugly dark spots in some of my finished pieces and they turned out to be metal particles that were thrown out when I was cleaning up welds with a grinder. You would be surprised how far the grinder shaving fly... some right into my slop bucket!
I am more careful now and never aim the grinder anywhere near where the clay is being worked. I also have a fine mesh screen over the slop bucket. It slows down drying time but Keeps, at least the big chunks out. I also put a garbage bag over my wheel to keep stuff from getting into the wast tray.
Same thing for me that has had me spreading the two aspects of my studio to the far ends. Clay is on the far left, glass/wood in the middle, and metal on the far right. My angle grinder is my best friend on most days and I find that the dust can go the distance. Not to mention the wire brush pieces that fly off during use. I find them in my laundry. Ill be at work and wonder what is poking me on my shoulder...yep metal wire.
Chantay just use it as a test clay like the others have mentioned. Even for test glaze tiles, considering if there is a leeching of the metal after firing youll know it wasnt in the glaze. I have some old terra cotta that got plaster flakes in it that I use from time to time as throw away pieces. You could even use it to make supports for clay pieces during firing.
