Beautifully presented, but how on earth did you think to even try this?
#6 and #7 look like automotive logo designs; I could imagine one on the hood of something fast--

( how on earth did you think to even try this? )
We use DEF at work and I noticed that where ever it was spilled and dried it left a crystalized residue.
So I checked it out with the microscope using X polarized lighting.
It looks really good on its own.
So now am trying different things mixed into it and have been getting some really nice results.
:D

Nice crystals. Some look like spaceships to me.

Hello,

After my earlier mistake of assuming DEF was the condensed moisture one sometimes gets on startups, and learning it is an additive injected into the exhaust system to reduce NO2 emissions, I looked at the makes up and see it is aqueous urea solution made with 32.5% urea and 67.5% deionized water.

At any rate - wonderful shots and very interesting.

All the best,
Mike
