Hello,

I'm using microcrystalline wax with a melting point of 175F in a focusing screen application.

Procedure:

Two microscope slides are held apart by .1mm spacers on ether side. One of the ends is dipped into melted micro-wax. Through capillary action, the wax fills the space between the slides. Optimally, a "grain-less" .1mm thickness of wax should form after it cools.

--I have yet to achieve a completely grain-less sample(visible to the naked eye under light)

My questions are:

1) Does melting micro-wax multiple times affect grain size?

2) Does heating micro-wax past its melting point affect grain size?

3) Does cooling micro-wax too rapidly/slowly affect grain size?

4) What is the best way to purify micro-wax? (I'm currently melting the wax, allowing impurities to fall)

Thanks for any suggestions, I hope I put this in the correct forum.
