Hey, guys. Have any of you been contacted by Jason Kimberling from Hess Pumice Products in Idaho? He emailed me asking if I would like to try their product which is a ground white pumice. He sent me some samples and I have been using it for about a month on a select few of my chins. So far, It seems to work as good as Blue Cloud. He has more than one grade and you can get the non-crystyline pumice which does not cause respiratory irritation. I will be emailing him in a couple of weeks to let him know how well it works, I want to check first to see what it does with an ebony coat since it really shows if the dust sticks to an eb. I do not know what they will be charging for it, but will ask when I email him. the Hess mine is huge and looks like it is there to stay for a good long while. They have a website if you want to check them out. Just google their name.
