Thread: Naturals' colors

Tony,
I just used the stone with a slurry. Definitely not a fast cutter, and feels smooth on the edge. I think I did over 70 laps and there was not much metal removed at all. So this leads me to think that it is not a Hunsrueck. Honestly, I think I would have liked a faster cutting stone than what it is How fast do the Hunsruecks cut? (comparatively) Lapped and with slurry, my stone looks very much like a regular Escher and I have the label that I have seen on the stones sold by Kees.

Eric,
I am pretty sure they aren't Manufactum Thuringens. Kees said they come from a small family operation, iirc

Pilot,
Kees sold a few under his ebay name Roos something something (number, including 0 and 6, iirc). Not an e-bay store. PM him here if interested, he is always very helpful.

Cheers
Ivo

He would be a seller I would trust and i have one of his stones in my collection. I don't expect every dealer goes through that trouble.

Tony

Ah, quite possible - so I have the same Muller stone then. Thank you for clarifying this, Tony.

Yes, I hear that a high percentage of stones have to be returned. Kind of makes you wonder - why do they even send them...

Cheers

Ivo,
To make it even more complicated there are at least 3 Muller firms in Germany selling abrasives. Of course Muller is just about the most common name there too.

I swapped a 5k shapton for a thuringen with kees and i asked him:

Yep!! Didn't you know? It has been mentioned in several posts on SRP.


So I think Tony has it right, in that, while Kees doesn't get his stones from Manufactum, his and manufactums stones are from the same source. Havent played with it too much, but it is quite slow

Yes, Tony - I remember reading about it. I think there are some variations in the spelling like Mueller vs Muller or something but nevertheless, I just meant that my stone came with the label that I saw on the stones Kees was selling

This settles it, Eric! I am sorry for the misinformation I spread - I understand now that Kees and Manufactum get the Thuringen stones from the same source. I absolutely agree that it's very slow after some work.

Guess I was right to think it's a Thuringen (vs. a Hunsrueck) - in hindsight maybe a Hunsrueck would be better if it cuts just as fine but much faster...

I thought I'd add some more info to this thread. Here is a map of Germany, note the area of Thuringer (in grey) in the middle is actually quite large, and accounts for the differences in the stones which can be classified as "Thuringers/Thuringians"




Here is Manufactum's website where they sell their Wasser-Abziehstein (water sharpeningstones) for 19 Euros (roughly $26 USD). The stone is about 7"x2"x3/4".

Here is Wojtec's ebay store where you can get a 6"x2" "Hunsruek" stone for about $35 or an 8"x2" for $47.

Here is Tony's store for Thuringen stones. He might not always have them in stock, but he has a listing on ebay right now here.

I'm not sure, but I think you'll have to PM Kees for a sale on his stock.

Wow, the region is really big. I've been to Erfurt as a kid... Anyway, I think different colors may well come even from the same mine - from adjacent veins, due to various elements... whatever

Looking at Manufactum's product - yes, the same label as my stone. It came lapped (checked with pencil grid) BUT lapped with something quite rough

Cheers
Ivo
