Butterfly Wings
Armenia, 12 Apr 2019
Here is a closeup of the wing of a Sunset Moth, taken using my Mitutoyo 10X objective. 
 
I could see making prints of mosaics or collages of say, these scales from half a dozen or a dozen different subjects.  Printed large in a grid on canvas.  Or say, eyes (human, mammal, insect).

Crystals
Armenia, 6 Apr 2019
Crystals can be grown on a microscope slide and then photographed using polarizing filters.  There is an effect called Birefringence that results in amazing patterns in some materials.

Below are some images I have made.  Most of these were taken at 20X magnification and are approx. 2 mm across.  The rest were at 10X and are approx. 4 mm across.  Please click on an image to enlarge it (then the browser's back button to return) or click on the Size options to the left to resize all the images.  The first one on the left is presently my favorite.

many people are probably thinking: stacking. But with stacking the layers of this crystals would have been lost. Without stacking you can still see that they grew on top of each other, and the image has some depth. It's Tartaric acid with Cetylalcohol.

After looking through some old slides I found many changes in the ones that had not detoriated. This is a very old slide I made of Stevia and another brand of sweetener. The 'pointilist' appearance is new, and adds to the picture.
I just got my hands some dry l-glutamine, ascorbic acid and citric acid to try and make some crystals for polarized light. Do you have any tips on how to prepare these 3 chemicals to get some nice crystals?
Loes Modderman: I have a lot of tips. Keep your chemicals apart. All three are easily soluble in water, normal tapwater. Put half a teaspoon max in a small drop bottle or a testtube. When it is dissolved, you can put two or three drops on a slide, apart or mixed, whatever you want. Prepare your slides beforehand by washing them in plenty of soapwater and drying them between two towels. That way you can use the WHOLE slide, for drops are much harder to crystallize. Spread the drops out, and heat the slide till crystallization starts. I used to do the heating above a waxine tealight, moving gently. When crystals appear, put the slide on a cold surface, your table. Crystallization will continue. But first of all, put polarization filters in your scope!!! Coloring with any color never gives the same results. You can check out all the crystallization pictures put in this group, and read my article in MICSCAPE, May 2019, to get a lot more tips!!

Do you use saturate solutions or less? Which concentration do you use (if is not a secret)? Deionized water?
Rodolfo, no secret. Plain tap water. and no, not saturated, just a little bit, half a teaspoon at most of the pure chemical dissolved in about 20ml. I never weigh or measure anything, I just make a solution and see what happens. Saturated solutions tend to become sticky before they crystallise. With my method they crystallize quickly most of the time when heated a bit, sometimes in seconds, depending on the chemical.
heating? I always thought that heat is the enemy of cristalization ...

"BIG crystal growth (if that's what it is on 1mm²) from Hydroquinone and a soft drink. Fascinating because they never touch other groups of similar crystals, but intrusions of a different kind are added without a problem. For people who want to learn something about crystallization !"
"The proportion of the two solutes is critical to achieving these forms - I generally start from a solution of 4:1 (v/v) of beta-alanine to l-glutamine and vary concentrations until I get something that works. Ensure that your slides are extremely clean - if they are even slightly hydrophobic the results are generally unusable."

"Extract of white snus. White snus is based on the traditional Swedish oral tobacco product but instead of containing tobacco, it contains a gum base to which nicotine and flavours have been added (mint flavour in this case). I took one sachet of snus and allowed it to steep in a 50:50 mix of water and alcohol for 10 minutes I then filtered the liquid through kitchen towel before leaving to airdry on a slide for a week. Images are taken using x4 objective and simple polarized light (no retarder). Slide shown as well for reference."

I just got my hands some dry l-glutamine, ascorbic acid and citric acid to try and make some crystals for polarized light. Do you have any tips on how to prepare these 3 chemicals to get some nice crystals?
Loes Modderman: I have a lot of tips. Keep your chemicals apart. All three are easily soluble in water, normal tapwater. Put half a teaspoon max in a small drop bottle or a testtube. When it is dissolved, you can put two or three drops on a slide, apart or mixed, whatever you want. Prepare your slides beforehand by washing them in plenty of soapwater and drying them between two towels. That way you can use the WHOLE slide, for drops are much harder to crystallize. Spread the drops out, and heat the slide till crystallization starts. I used to do the heating above a waxine tealight, moving gently. When crystals appear, put the slide on a cold surface, your table. Crystallization will continue. But first of all, put polarization filters in your scope!!! Coloring with any color never gives the same results. You can check out all the crystallization pictures put in this group, and read my article in MICSCAPE, May 2019, to get a lot more tips!!
   - The Seven Most Common Grades for Chemicals and Reagents:
  1. ACS grade meets or exceeds purity standards set by the American Chemical Society (ACS). This grade is acceptable for food, drug, or medicinal use and can be used for ACS applications or for general procedures that require stringent quality specifications and a purity of ≥95%.
  2. Reagent grade is generally equal to ACS grade (≥95%) and is acceptable for food, drug, or medicinal use and is suitable for use in many laboratory and analytical applications.
  3. USP grade meets or exceeds requirements of the United States Pharmacopeia (USP). This grade is acceptable for food, drug, or medicinal use. It is also used for most laboratory purposes, but the USP being followed should always be reviewed prior to beginning to ensure the grade is appropriate for that methodology.
  4. NF grade meets or exceeds requirements of the National Formulary (NF). The USP and the NF (USP– NF) jointly publish a book of public pharmacopeial standards for chemical and biological drug substances, dosage forms, compounded preparations, excipients, medical devices, and dietary supplements. The listings here should be reviewed to determine which would be considered equivalent grades.
  5. Laboratory grade is the most popular grade for use in educational applications, but its exact levels of impurities are unknown. While excellent for teaching and training, it is not pure enough to be offered for food, drug, or medicinal use of any kind.
  6. Purified grade, also called pure or practical grade, meets no official standard; it is not pure enough to be offered for food, drug, or medicinal use of any kind.
  7. Technical grade is used for commercial and industrial purposes; however, like many others, it is not pure enough to be offered for food, drug, or medicinal use of any kind.
      ACS, Reagent, and USP-NF grades are typically equivalent and interchangeable
