In previous geological post I created a woolly colorway of Sandstone.   Second in my geological series of the mountain, and underfoot quite a lot, is shale.   A refresher of a quote from a reliable local vintners’ source, they who take the geology of this appellation very seriously…

Mount Veeder is primarily an island of ancient seabed, pushed up in the mountain’s formation five million years ago.  This is the only Napa Valley appellation that can claim this unique geologic phenomenon. While the rest of Napa Valley was covered in volcanic ash 1 million years ago during the eruption of Mount Saint Helena to the north, Mount Veeder received just a sprinkling. Within the marine soils lies a complex tapestry of fractured shale, sandstone, volcanic (ash) dust, and other various constituents.  — From Mt Veeder Appellation

This rock I have seen in some places mounded up into nearly hill-sized formations which I suspect to be left behind by an ancient volcanic upheaval.  Hard and a bit brittle, this broken shale is generally dark charcoal grey,  although sometimes a medium grey.

To achieve this color I use colors from the color-saturated neutral, blended with undyed wool shades of  natural black and natural grey.

And as natural black and brown fleeces are amazingly varied in breed and color, so can be this shale colorway, ranging from medium grey to almost black, just as the rock is.

Stay tuned for geologcial 3,  which will be a woolly colorway of yet another geological composite.   Very pleased with the charcoal/black in my  tweedy palette, I give you the recipe I have written for “Shale” …

Techy stuff for Shale…

• Began with Primary & Secondary Neutral recipe using approx 2.5g each of green, purple, and orange  AND  blue, red, and yellow, (or alternately 5g each of primary or secondary triad colors) blended thoroughly on blending board (see Blending For Tweed Simplified) ,lift batt, set aside.
• Layer 15g natural black with 15g natural grey,  lift batt.

Note: This blend is 50/50 black and grey. For darker color blend more black and less grey, and for lighter blend more grey, and less black.

• Layer color-saturated neutral batt with black/grey batt alternately.

• Lift batt, layer again.   Layer once more for a more homogenized result, or go on to next step.
• draw off rolags.
• Colorway blend:  ” Shale” .

Inspired by the rock forms of the mountain, I have created three more colors in my palette, introduced in three parts.  But first, let me borrow a quote from a reliable local vintners’ source, they who take the geology of this appellation very seriously…

Mount Veeder is primarily an island of ancient seabed, pushed up in the mountain’s formation five million years ago. This is the only Napa Valley appellation that can claim this unique geologic phenomenon. While the rest of Napa Valley was covered in volcanic ash 1 million years ago during the eruption of Mount Saint Helena to the north, Mount Veeder received just a sprinkling.

In my observation the most prevalent of these three mentioned geological rock forms must be sandstone, ranging from a dull tan, to a rusty brown and sometimes sparkles with colors, sandstone is the color of everywhere …Especially at the summit of the mountain these rocks are of rather large proportion, and an outstanding geological feature.   Sandstone, with color-saturated neutral base, so like the true rock form created from a composite of many grains of colorful sand, blended with natural white and natural brown wool …

The nice thing is, using natural brown fleece, there is quite a variation of color, and as I blended with natural white, even more of variation of natural values & hues can be accomplished.   Just as the rock itself is so varied in color, the Sandstone colorway is too…

Next , in Geological 2, I will produce a woolly colorway of another popular rockform, but as yet, I am waiting for my wool to come in the mail!     Until then, here’s how I made “Sandstone”  …

• Lift color-saturated neutral batt, set aside, and blend 7.5g each of natural brown, and natural white.

• Combine layer of color neutral with brown…

• Lift batt, layer alternately with 7.5g each more of natural brown, and natural white.  Note: In second blending, for a browner tone, continue with only brown, omitting the white, and for a creamier beige tone,  omit the brown.
• Draw off rolags.
• Colorway blend:  ” Sandstone” .
