Thanks for the response & practical wisdom, Neil!
If I may pose a question -- would adding combustible material to the slip, or applying it after the slip is dried on the pot, be a terrible idea? Or another way to ask the question -- why would that not work? Would it essentially create the atmosphere that I am attempting to avoid? Just trying to find some clarity on this, as there doesn't seem to be much information out there on the matter.
Along that vein, what elements are present in Shino that create the flashing, and is it possible to merge the two to perhaps have some of that effect "cross over?" I'd like to eventually not be a newbie with all this, thanks so much for your time!
