: would not appear gritty since it is so fine. I have checked my
: titanium dioxide and it is extremely fine even under 300X
: magnification. My skin flakes from my dust filter were much larger!
: HA HA!! This $20 toy microscope has been lots of fun!
At the resolutions I'm useing, fine stuff could by me. I'm just
testing for a few things like obvious grit, plant debris and dye. The
basic nuisance stuff that hangs people up. I'm working between 10 and
50x so I can easily scan over a sample and see what's there. Most of
the samples I have are boxes of henna I've picked up at Indian markets
and suchlike. People often post here fussing about henna they bought
at a store that does nothing but clog, jam ... so I'm surveying all
the henna I've ever bought or been sent just to see the comparitive
debris levels. Seemed to me that a comparison of "what's in it" would
be of benefit to people who wonder why the box of henna they bought
sucked so bad ... and it might nudge some exporters to stop sending
over crap henna on the assumption that stupid Americans will buy anything.
I could go up to higher resolutions and see what's there. This
weekend I'll ask my husband to help me hook up the microscope to my
computer so I can photo a few of these and post pics...
