Enjoy your LGB. I have got one myself, and although it's not the easiest coticule to work with (significant slurry dulling, requires precise dilutions when doing DiluCot), you'll be rewarded with perfectly mellow, smooth edges. I do love mine. :love:
I'll add that I don't really know what it is and could believe that it's LGB (like no. 46 in the Vault, possibly). I'm just curious how the layer was determined since my first guess would be different.
In the quarry they know from,which layer they mined it. They've just started on top of a new quarrying location.
It looks streaked like often seen at La Dressante. It has the tell-tale white lines of La Veinette.
But I've seen both properties on La Grosse blanche as well. If after a while, the narrow sides that never see use start to turn to a significant darker color (chocolate brown eventually) you can be sure it's a La Grosse Blanche.
Or if it came with a certificate from Ardennes, you know for sure too.
It's a lovely stone.
Enjoy using it, that's the important thing!
For whatever it's worth, my La Grosse Blanche took months to darken after exposure to intense sunlight. I don't know if this is normal for the layer, or perhaps my example is just a slow learner..
With narrow side, I mean the unused sides of the hone, hence not the surface you hone one.
The darkening of La Grosse Blanche is not fully understood. Light and perhaps humidity are of influence. If you mask part of the side with a piece of non-translucent tape, you should be able to notice a difference in color after a couple weeks.
