There's been some discussion on these boards about whether the hybrid side on the Les Latneuses is really a true hybrid (read: mixture of yellow coticule and BBW) after all. In some stones it certainly appears to be very hard.
One thing I've noticed is that in natural combos the interface between the yellow coticule and BBW layers is usually very sharp (though there are sometimes streaks of blue in the yellow layer). As in this stone, for example:
(Don't worry about the dishing on the coticule layer on that stone, I only use the BBW on that one anymore.)
Now I've got a slurry stone from an unknown layer that seems to have a gradual increase in 'pinkness' at the interface between the coticule and BBW layers. Note the fuzzy interface between the layers in the pics.
I was wondering if that pink layer would be a more ideal 'hybrid' layer. It does seem to have a mixture of BBW and yellow coticule. I've seen coticules with pinkish tinges, so could those be coti/BBW mixes?
Also, does anyone have an idea what vein this slurry stone is from?
NOTE: The pics do not show the true 'pinkness' of the interface between the coticule and BBW layers. It's actually quite pink, with speckles of yellow mingled in. It was hard to capture, and it doesn't show up well here.
I'm looking forward to hearing your views on this.
