Optional fiber reinforcement for tufa
May not be original but haven't seen it suggested to date but have found what I believe to be a reinforcement fiber that I think is superior to the typical fiberglass I had been using. I had a piece of braided poly rope in my shop that had started to unravel at one end and a light came on. I cut the individual braids into several length and unraveled the individual strands. Mixed them in my next batch and had no problems with clumping. Also believe it to be much stronger than the fiberglass. I can adjust the length of the fibers with a pair of scissors or a razor knife. So far so good. Don't see any down side yet. The fuzz burns off exactly like the fiberglass. The rope I have is white but I imagine ski rope or something similar would work as well. Anybody know any downside before I do any more ?
