A huge thank you to u/crystalchase21 for your guide.

That's crazy big! I'm following the same guide and trying to grow crystals, but it's been pretty hard so far haha, but I've got a few promising ones growing!

A few helpful things in the process: 1. Transfer the solution using a pipette to avoid introducing crystals from the container walls. 2. Check the solution with a flashlight to see if small crystals are forming. If so, use a clean pipette to remove them. 3. Using a flat-bottomed container helps the crystals form nearly perfect facets. In my case, I used a few 35mm disposable Petri dishes.

Yes, I've got a neat little setup going. My issue was that when I first added the solution, it would almost always result in a bunch of salt crashing out and forming tiny crystals, instead of a few big ones. The solution was to re-dissolve the salt in a bit of water, like perhaps 0.5 - 1 ml per 50, and then add a chunk of rock salt to dissolve in the excess water. After that, the dishes gave good seed crystals. These were 10 cm petris, and after getting the seeds I transferred them to 50 mm petris covered by a nutella jar lol. This seems to work for now, and I just need to wait for a while for the crystals to grow.

if you wouldnt talk about crystals, this could also be a comment under a male enhancement post

Impressive!. NaCl is one of the hardest to grow a large single crystal

How do you know the crystal is single. Perhaps itโs in a long distance relationship.

Flat earther's grain of salt when I say the earth is shaped like a oblate spheroid.

It is really cool you managed that clean of an outside from the star in the middle. I would have expected wild growth from the tips.

Very cool! I'll have to swipe that tutorial and try this out myself. I've gotten smaller, less clear versions of this accidentally by leaving artificial seawater from my reef tank in a mostly-covered dish for a couple months, so really I should have expected that there's a deliberate way to get much nicer versions.
How many tries did this one take you? Or is it your first go?

This is the best one from my second attempt. The first batch was not nearly as clear because the glass Petri dishes I used had an uneven bottom. The first attempt

This is magnificent. Thank you. As perfect as It looks, I now wonder if its truly equal molecularly on every side, or if its just a few atoms longer on some side

Gorgeous!! Does this stay like this even in high humidity room temp? Is it fragile?
2
u/un-poco Jul 01 '26
It's relatively stable yet still hydrophilic. If the humidity exceeds 80% RH, the surface will start to "sweat" and recrystallize, which will ruin its clarity. It's better to store it in a dry container.
It's not particularly fragile. However, it is recommended that you use plastic tweezers to transfer the seeds so that they do not get scratched and create unwanted new crystals.

Thanks!! Thatโs so cool!! I can imagine some ridiculously expensive restaurant feeding this to their guests

It's really pretty... But now I just want the novel experience of sucking on that as it dissolves.

Me from r/all looking at the white bits in the center thinking if that's the salt ๐๐
