Something square
Here is today's 200X picture.
It's a little out of focus, but it's a transparent grain.
On the right side, it is a square-like Tsubu.
Is it some kind of crystal?
Recently, it has been a bit of a villain, but since ancient times it has been a medicine, a source of life, and a military substance.
Salt. Salt at the kichen.
If it was a more solid crystal salt, would you have been able to see the angular part?
I will try it next time.
What I had at home was a moist type of salt that contained a little moisture.
Unexpectedly, the grains are stuck together, and the thing itself is clean and transparent.
Sodium (salt) is so familiar that children will make fun of you if you say it's a kind of metal, so be careful.
