Thread: Hones under thr ProScope HR

Indeed you are correct… many thanks… now I can go back to the old skin.

I never thought to simply mouse over in the old skin… to see the often ignored .jpg file name that pops up… legend?

Interesting views of the hones.

Interesting. It really looks as if the YG escher is much finer than the grey and blue escher.
I know these are the most prized and expensive ones, but it is nice to get an idea of why this is.

Hey rich, perhaps it would be a neat idea to show what these razors to to an edge?

Nice pics. Thanks for taking the time to post.

Great pics! If you take pics of the slurry you'll see the famous red garnets in these stones.

When I first saw these pictures the I couldn't help noticing the strange colors. I suspect that's chromatic aberration from the poor optics, but I don't think we can derive any meaningful information about the colors of these stones.
So, I took pictures of some of my hones with what I believe to be much better optics (vintage leica and modern canon) and electronics (canon, made to produce photographic quality). I put them in a new thread.

As far as garnets go - I'm yet to find any on the surface or in the slurry of a thuringian stone. I don't think the cutting media of those is garnets.

They definitely contain garnets, I saw them myself. Once you have seen one you'll never miss them again. Belgische Brocken have pics on their site of slurry with garnets. You need a magnification of 100x to see them.

Yes, kees, the garnets on the belgian stones are all over the place. In fact the pictures that I jsut took should have at least a few of them. Also belgisher brocken is only for beligan stones afaik.
But if you've seen garnets on thuringian, I suppose, they have them. I just have never ever seen a single garnet and it's not like I haven't spent enough time looking...

From what I've read, and I'm no expert by any means, I thought Thuringian stones were silica based cutters and did not contain garnet. We should get Tony Miller or Howard Schechter to add their opinion or knowledge here. I've never seen garnet in the handful of Thuringians I have either. On my Belgians, the garnets are noticeable and under higher magnification if the light is right have actually cast the deep crimson glints probably from a facet from the stone that garnet is so beautiful for.

I have had a look again. I think I can see them in both my Y/G Escher and the vintage Thuringian.
The slurry particles of vintage Thuringians and Y/G Eschers are much smaller than those of the NOS Thuringian and coticule. You can see them at 400x and 1000x (oil immersion) magnification.

If you just look at the slurry you won't see them. However when you move the objctive slowly up and down with the fine adjustment (=fine focus) knob you'll see some particles turn red for a short while.
I have always thought those particles are garnets however I stand to be corrected.

the timbertools people and howard say that eschers contain fine grains of quartz (silica) and that this is the cutting medium. both say that there are no garnets in these stones. i've seen garnets in the belgian stones but not in the eschers. garnets are harder than quartz which probably accounts for the faster cutting action of the belgian stones.
