? nylon fibers in clay

Dear Susan,
Nylon fibers look like unpacked cigarette filters. I mix them into some
hand building bodies in a Soldner mixer by stirring them into a 1/2
gallon container. I use a small handful and swish the clumps away. Then
put the mix into the batch. This additive does lend some resilience and
allows for thin walls. I also add a lot of grog of various sizes and I
am not concerned with the super thinness. I just added some to a paper
clay terra cotta for a large structure. Will see how that works.
