How often do you clean out a pug mill, in pounds of clay probably. And...

How hard do you pull down on the handle? I put quite a bit of force on it, but I'm not absolutely certain that is necessary.

Thanks,

I will likely be purchasing a pugmill in the next few weeks. I've used a 3" Venco and like that machine, but it may be too pricy for me. I'm currently using a Bailey and I'm not a big fan, but it may just be set too high (my main complaint is the work it takes to pull the lever down). I've also used a small Bluebird and that isn't an option at all. The Peter Puggers look way over priced. I don't know anything about the Axner or the Shimpo. Does anyone have any recommendations or suggested bullet points to take into consideration?

Do electronic kiln controlers actually simulate heat work on pyrometric cones or do they just measure air temperature?

I noticed years ago that there are two layers of glaze on a bisqued pot, dipped specifically. There is the glaze and if that layer is chipped off there is a faint layer of residue. Then there is the bisqued substrate. I just got to thinking today about that and wondered if anyone here knows what that residual layer is, and/or is called?

I can't find any recipes for a cone 6 "color active," or fluxing slip. I'm really not sure what designates a slip as such, beyond the presence of more than normal percentages of flux(s). If I were to use a lower cone slip would it act like a color active slip?
