Now playing: Nikhil Banerjee - Bhairavi - Gat in rupak tal

Darren Fox, aka “Brother MOLOCH”, posted an interesting
question to the Hyatt list today, regarding the identity
of the ‘Bluestone’ originally employed in Hoodoo.

Since the currently available Bluestone of the trade that
is found in Botanicas &tc. varies widely in both nature and
quality, it is not a bad idea to see if perhaps the identity
of 'Bluestone' might be resolved, so that an authentic
substance or composition might once again enter into
common usage.

There is some debate about this. I've seen the claim that
the original Bluestone was Copper Sulphate, also known as
Blue Copperas, and as Blue or Roman Vitriol, which requires
some care in handling as it will burn you or anyone it
comes into contact with rather badly.

Copperas as Blue Vitriol < and distinct from Green or Iron
Vitriol > turns up in many dyeing procedures that call for
Indigo < and lime >, as it enhances the action of the Indigo
within the fabric being dyed blue.

Yet another candidate for Bluestone is Azurite, which was
anciently and still is employed as both a pigment and in
the fashioning of jewellery.

Azurite served as the default and more common replacement
for the rare and expensive < quite literally more precious
than Gold > *Lapis Lazuli* < literally 'blue stone' >, or
Ultramarine, obtained 'beyond the sea' from mines in the
Kokcha Valley of Badakshan, now northeast Afghanistan.

In the early 1800s, artificial Ultramarine became widely
and inexpensively available, and the once rare and precious
commodity was pressed into service as common laundry bluing,
along with Prussian Blue < Ferric Ferrocyanide >, which is
a dark blue pigment more commonly associated with
engineering and architectural blueprints - as well as the
smeary and smelly blue mimeographs some of us may recall
from our school years. Prussian Blue is obtained from Green
Copperas, or Iron Vitriol.

One can purchase synthetic ultramarine pigment in powder
from any fine arts supply house - I recommend Sennelier's
'Ultramarine Deep' Fine Dry Pigment. Less than twenty bucks
for three ounces.

A mixture of equal parts 'Ultramarine Deep', Sodium
Bicarbonate and powdered chalk < calcium carbonate > will
give you a fine laundry-grade, people- and environment-
friendly 'bluestone' powder similar to what my Grandmother
used in her washing.
