Getting All Bugged Out (Was: Have any of you started creating bugs yet?)
Oh we're on the same wave length. I got my laundry done and am getting
chores out of the way today too.
Because we were talking about "Living Jewels" and looking at pictures of
bugs that have metalic colored wings I mentioned it to my girlfriend who
as a cosmetic chemist. She is so smart about such things, makes lipstick
formulas and such all. I was moaning about how I don't have Pearl
Ex powder and
even if I did I've not seen any that have the saturated color that these
So she sent me 101 small samples of colored mica! The box came in this
I just about fell over. As a miniaturist the little plastic containers
have made me happy even if they were empty. But these were filled with
mica samples and they were labeled with a name and I think the
name on most of them.
For the last couple of days I've been making an inventory of the
on the small containers and looking at this pallet of powders and the
just gobsmacking amazing. The saturated colors are the like that we
don't see in
craft stores. Some have two colors depending on which way the light
I asked her for links to where these powders are bought. They are used
cosmetic industry so the sites are geared for that and not for arts and
(Rona is the cosmetics division of this company and they
make all the pearls)
(these people invented pearls! they were originally Merle.
they also make REAL pearl powder.)
(another option but limited)
(prespearls are supposed to be cheaper.)
I asked my girlfriend what are the chemical properties of these powders
told me. Then I did a search for the chemical properties of Pearl Ex
it's the same thing.
So I'll be working with something I've already had exposure to. Since
powders meant to be in cosmetics, soaps, shampoos and moisturizers, they
be smaller particles, ground up real fine. They are supposed to be
safe since they go into cosmetics, one would think. With all powders one
be careful, wear a face mask, don't toss the stuff around like you're
glitter party, that sort of thing.
I'm building a web section to share this information and I figured if I
black clay as a blank canvas and experiment with these metallic powders
see if my theory that using these saturated metal colors on black we
replicate a real wood boring beetle like this one.
I was thinking of making one beetle, curing it, making a mold of it,
a couple of hundred black beetles. 101 beetles to show what each mica
looks like stand alone. Another batch to mix colors to see what we can
with. My girlfriend said that putting the powders in some sort of
acrylic floor polish or TLS would be the best bet, then applying a
it after curing.
So I'm getting all Bugged Out on this experiment. I'm learning more
chemistry than I ever imagined. I'm thinking maybe there's another
source of these pearl powders than at the craft store, eh? I like cheap.
So here's a big hug and tons of kisses going out to Irini, who was so
to us. I say "us" because all this information is going up on my
But that's not the secret thing we've been working on, just in case you
have thought it was. LOL

Some more information on the "Pressie
"Pressie" is a term for presents. ClayMates from the UK, Australia
Zealand have used that term.
More information from my girlfriend:
"They are sorted by particle size and chemical nature. 15 to 150 mircons."
Oh I'm so glad I didn't mix up the samples. Just took them out of the
logged them in an inventory and put them back, so they are still sorted
"The particle sizes are pretty big. Up to 150 microns (look at the
are the largest.
Particle size is very important for feel and visual affect and emulsion
the ultradescence are the smallest particle sizes."
Some of the trade names:
"What is plated on which substrate also determines the visual affect.
light and absorbed light play a part.
Do you have pigment there? hmmmm? Which ones? That plays a part.
colors are titanium dioxide plated unto mica,. sometimes silica. One of
sites given there is small talk on optics and the effcts of interference
You might want to know about mass tone and reflection. Some people call
flash or sheen."
"But you must not confuse the micas with the calcium sodium
calcuim aluminum borosilicates, the
silicas, and the pure titanium dioxide. they are not all micas."
That's right, mica is an ore.
Typical Chemical Analysis
Silica (SiO2) 73.5%
Alumina (Al203) 15.0%
Iron (Fe2O3) 0.15%
Soda (Na2O) 3.0%
Potash (K20) 7.0%
Lime (CaO) 0.3%
Magnesium (MgO) Trace
"acrylic floor polish:
I don't think you can credit me with that one but it is another idea. I
recommended clear nailpolish or clear acrylic
media (used for painting in acrylic paints, go to your local art supply
I thought we discussed acrylic floor polish. Well, it's one thing we
hand and we can experiment with it. TLS too.
Speaking of bugs, there's a bug that's used for pigment, and in a lot of
we eat and we don't know it. Hmmm.
This is an interesting link she sent. It is good information for those
Kosher or Hallal foods only.
Now I know this is a bit more than most clayers want to know about
glitters and shines, but it doesn't hurt to know what's in the products
using. It also doesn't hurt to look for other outlets for powders that
saturated color that we can't find in the craft stores.
So as I get more information I'll be posting it here so it'll be easier
to gather up this information when I make web pages about it.
I still got to find some box or tuppa ware container to hold these
without mixing them up.
