Thread: Correct use of a Thuringian/Escher

So I think I have finally gotten the use of a Thury down pat with water or dry.

My question is, if I use it with slurry how "low" of a "grit" can one achieve? Is it like a coticule where it will go very "low", like to "1k"? Will it only go "4k"? "8k"?

Please notice the use of snear quotes please. I know that naturals are all different and cannot be rated. I am just asking if I use a slurry where can I aim to fit it in to my rotation?

Background info: I am asking because I am deciding about splurging for a biggish Thury (8x2) or hunting down a vintage one (7x1.5). If it ends up as one of the "NOS" Mueller ones I know it would most likely be coarser than a typical Escher. I am okay with this if with a slurry I could go down in "grit size" because I have a 5x1 Thury already that gives amazing finishes but is too small to be useful for anything more than finishing.

I mostly just want to know what "sharpening grit range" I can expect from a Thuringian type hone.
