Hope you enjoy using the site! If you have any questions, U2U (kinda like PM-ing) someone. Nice picture, too!
I must comment, glad to see you are on the site! There are not very many females that are interested in chemistry, let alone state their gender.
Regardless of stereotypes, enjoy the site. Is there anything about chemistry you are particularly interested in? Specific branches?

Allow me to extend that welcome - we need more women not in professional STEM (TIL female astronomers and biologists outnumber male astronomers and
biologists), but in hobby STEM, as that's where the interest grows.
Feel free to use the Sciencemadness Wikias a reference (and feel free to edit it as well). The thread discussing it has been topped and resides in Miscellaneous.
There's also the Rador Labs collaborative chemistry outreach project, which needs more interest and videos. Shoot me a U2U if you want the passwords.
Enjoy the site!

Found a 5000 cm3 Erlenmeyer flask written 0,5M NaOH solution of it and found these nice large crystals at the bottom. Single crystals of sodium
hydrogencarbonate/carbonate.
I have a blog where I post my pictures from my work: http://labphoto.tumblr.com/

Hey Nathan & B&F,
Thanks for the welcome. I was not aware I was special lol 
I've always seen myself as 'one of the boys'... in school I was the only female in my class. Never thought much of it.
I mostly like the 'kewl' chemistry, the spectacular, dramatic reactions(as long as it's safe. I tend to have a little too much 'respect' for some
chemicals, almost fear them... not healthy, especially with my job, where I handle those chems almost daily.), and I see beauty in the tiniest
reactions and displays, like the lead iodide crystals, or a water droplet skating off the hot plate(Leidenfrost effect ftw ).
I work as a School Science Tech on a high school. I assist the teachers with their practical classes. My background is Analytical
Chemistry(chromatografy, spectrometry that sort of stuff).
I love teaching, and my goal is to make every student love chemistry as much as I love it 
Rador Labs sound like an awesome initiative. Fighting chemophobia through education, always a good idea

Tried bfesser's Copper(II) Aspirinate Synthesis
Which turned out quite well.

Here's some copper(II) chloride crystals that I set out to crystallize months ago but wasn't able to retrieve until today, because they had been
guarded by angry yellow jackets until now.

Beautiful! I love how the copper chloride crystals have green tints - did you grow them in excess HCl?

Yes,
there was a little bit of HCl. I didn't want them to be too green. The first batch that I made was, and I didn't think it looked representative of the
compound. I like the way these turned out since they're mostly aqua colored with some green highlights. Especially cool is that the green only becomes
visible when you hold it up to the light.

It appears they were grown in excess HCl, but at least some of that excess evaporated off, because the crystal color changes partway. Not that
basement evaporation (what I do) is better than outside.

Strontium Chloride.
Strontium Chloride transferred to a vial.
Copper Chloride in a petridish, crystallized from a mixture of 50% acetone and 50% water.

Those are LARGE pictures... I liked the second one, because it has a sort of gooey feeling to it, while obviously being a group of crystals.

Nice work Jylliana! Inspiring! I like the strontium chloride especially! Looks rather pure, too! I might recommend the acetate as well, it, too, has a
nice looking crystal structure.

To celebrate 1000 posts and a year on the forum, here is one of my favorite pictures of all time: pyranine in neutral to progressively more acidic
environments. The dye's fluorescence changes from green to blue.
I may make a video series regarding fluorescent pH indicators from highlighters.

I work in a Drosophila lab, and in particular I've been doing some scanning electron microscopy. Here's some cool stuff I've seen:
The samples get sputter-coated so that charge doesn't build up on a nonconductive surface. Basically I blast a fly in the face with plasma.
Here's the microscope itself:
Things get pretty Lovecraftian at this scale. Eeesh.
In the back room of the SEM lab: Oh, you know, osmium tetroxide, sitting on the lab bench, chillin'.
And an open bottle of this lovely substance.
(There was also a bottle of 'uranyl acetate waste', but it's not very photogenic unless you really like the color yellow.)

From the look of that can, that's an utterly ridiculous amount of osmium tetroxide to have. The picture makes it look like that's a 1.5L can. Surely I
am missing something here?

Doesn't it say 250mg on the left top? These cans always contain a load of packing material against breaking.

That's crazy. How much did THAT cost? And what's wrong with permanganate? Or do you always recover the osmium Tetroxide?

Yes- the can's not full of osmium tetroxide, it's full of vermiculite. In the middle of the vermiculite, there's a small bottle of OsO4.
Please remember: "Filtrate" is not a verb.

The condenser water was too cold during a distillation of benzene. It froze in the condenser, swapping the cold water for cool water melted it right
away.

Wow, that's crazy. I never thought of benzene as being something that could do that, but I guess it makes sense. You could almost put a 'cold finger'
(a piece of glassware for all who do not know) over such a flask, though I supposed it wouldn't be removed enough from the heat source.

The cooling water had ice in it and I forgot about benzene having a melting point of about 5.5 Celsius. A cold finger probably would have some benzene
solidify onto it but in this case benzene was being synthesized so the temperature in the steel vessel obviously would be too high for a cold finger
to even remotely work. Making this stuff is tedious by the way... Fill reaction vessel, heat, distill, empty clinker stuff, repeat. Ugh.
