French Vosgienne

I got my French Vosgienne today and I thought I'd share. I saw something real similar on here a long time ago and no one seemed to know what it was so I'm guessing there not commen. Also if anyone knows anything else about this stone I would like to know.http://uploads.tapatalk-cdn.com/2016...6cbfee695d.jpghttp://uploads.tapatalk-cdn.com/2016...8ed02c2b59.jpghttp://uploads.tapatalk-cdn.com/2016...dda33f36d9.jpghttp://uploads.tapatalk-cdn.com/2016...007f658f50.jpghttp://uploads.tapatalk-cdn.com/2016...f31cf8d940.jpghttp://uploads.tapatalk-cdn.com/2016...aa1cd2529a.jpghttp://uploads.tapatalk-cdn.com/2016...57fe231a35.jpg

Also it looks like someone painted the sides at some point and was scrubbed off at some point. Is this something I should be worried about. I've heard of Japanese stones being laminated on the sides to keep them from falling apart. It dosent smell like oil at all. http://uploads.tapatalk-cdn.com/2016...b1baf4e768.jpghttp://uploads.tapatalk-cdn.com/2016...6a1500e7b2.jpghttp://uploads.tapatalk-cdn.com/2016...432b596458.jpghttp://uploads.tapatalk-cdn.com/2016...d67be51721.jpg

In the width measure pic it looks to have writing, what does it say? looks like a date to the right and above?

How does the stone hone>??

I haven't tried honing with it yet. But if you're referring to the picture with the tape measure in it believe that they are embedded fossils.

Well, it is a good looking stone, did you get a good price on it?

I would say its a slate...i own several slates like this. Actually its difficult to point out the origin of any of those.

Mottled slate appears in many different regions of the world...

Iam actually trying to get some analyses done from a geologist. To get thin cuts of some stones. This would be the only way to try to compare those samples with others beeing already done.

The coloration comes from a Redox reaction.
Red comes from Hematite, green comes from Chlinochlor....

I also talked about "Vosgian Stones" to a certain time for my stones. I have to admit today this Term cant be proofed in detail....

I'm not sure. I paid $110 for it shipped. At first the guy didn't know what it was, but when I messaged him asking if it was a finisher he messaged me back saying that one of the ebay shoppers told him it was a Vosgienne razor hone. It's 8in x 1.5in

Do you think it would be a good idea to seal the edges? I'm worried about using it since it seems someone sealed the edges in the past. I don't want to destroy the stone.

Especially on slates there is a easy procedure to check if a Sealing might be useful...make the area where you want to check the condition wet...then directly dry it with a towel...

Now check how fast the surface gets dry...if there a bigger cracks inside the stone they will remain wet and look darker....

If you have many cracks i would personally seal a slate, if not a sealing is not needed

This Stone holds water incredibly well so it differently needs to be sealed. Do you have any suggestions on what to seal it with( preferably something clear so that way I can still see the grain)? Also is there any special care for a stone like this?

Actually there are many possibilities around which do go from classical natural sealing with shellac or Urushi Laquer (mostly done on Jnats)...i prefer synthethic clear coating.

For Jnats check Keiths page:
http://www.tomonagura.com/jnats/japa...ng-a-jnat.html

I use a clear coating (Hobby Line Acrylic Clear Coating) which is UV stable....

I also used Dupli Color Clear Coating on some of my stones which till now works well...

I use rust-oleum crystal clear enamel from the hardware store. 3-4$. Tape off anywhere on stone you don't want the spray to get to with painters tape. I also use a spray handle on the can which makes it like a spray gun. It cost a couple bucks at the hardware store too and just clips on. That way you can get a good even spray. Quick light swinging sprays. Just do a few thin coats and let dry in between. Go light with each spray or it will run and you can always add more.
