My first crystallisation Caffeine
Hi,
My first go at crystallisation, Caffein;. stacks of 7 images or so
BHT microscope with Nikon BD Plan 40/0.65 via direct projection on Sony NEX-5N
One 5000K bridgelux COB Led, Circular PL above source light, linear PL on Scope.
On the first two I forgot to add 50mm extension so corner quality was not that good and have some cropping. 3rd one has 50mm extension
Caffeine 1

Caffeine 2

Caffeine 3

I would like other suggestions on easy to get things to crystallise, because this is fun..

Re: My first crystallisation Caffeine
Have a look at the Facebook Crystal Art group. Great images and good resources in the file section, including a large list of birefringement compounds. BHT, Beta Alanine, Urea, Thiourea...

Re: My first crystallisation Caffeine
Do you have any advice on how to start with this?
It's quite interesting.

Re: My first crystallisation Caffeine
I am just starting with this too so I can not give much advice. The facebook group Dhmiller suggested is full of examples
This is just caffeine dissolved on a microscope slide looked through crossed polarizers; to me the biggest problem seems to find chemicals in pure form without having to buy a kilogram ..

Re: My first crystallisation Caffeine
I have a polarizer built, it looks like it works. I'm waiting for the fumes and I'll let you know if I have an output
Thanks.

Re: My first crystallisation Caffeine
Thanks, but I do not know if some of these chemicals are regulated and will go through customs OK, maybe is better I buy them in Europe? Any similar source?

Promised output.
I can't judge if there's enough detail in the picture.
However I am satisfied - first try + DiY "polarizer"
FOV 6mm, Lomo 3,7x, 2x led, transmitted light, APSC.

Sorry. I don't know any European sources.

Re: My first crystallisation Caffeine
Do not worry, I found some.
With the right names to look for and possible combinations is more than enough
Thanks!!
