A question came up recently as to whether it's not a good idea to use small witness cones instead of the large ones. I thought someone on the forums made a case that it wasn't a good idea, but I can't remember, who, or why or when.
A forum search (done properly from the main page) came up empty. The orton website says the small cones can be substituted in cases where space is an issue. Well, if they're interchangeable, then why not just use them since they're cheaper and take up less space? Unless, of course, you're trying to see them in the kiln, in which case the large ones will be easier to see.
Anyone have input on this?
