Wow, I order at least a ton a year for the last few years from Highwater. Never got anything but clay. Just got a pug mill and oops it chewed up my wooden rib. Time to be more careful!! Yes, I will screen my slop from now on and in any shared space with a pug mill everyone would need to push scrap through a screen. I used to run the pug mill for an Art Center, but had forgotten this.
