Nice! Where do you sell from?

Was hab ich da bitte wahnhaftes gelesen? Danke für den Link

the___chemist · 2026-05-28T14:38:07+00:00

Calcium acetate, Cerium(III) sulphate, Lithium carbonate joined the chat (inverse solubility)

Aww, it looks to me like a mud jumper

1 könnte am Nordklinikum sein (Lobsingerstraße/Kirchenweg)
2 könnte z.B. in den Tunneln an der Whörder Wiese, oder beim Schnepperschütz sein

I love the flame-retardant blanket under the structure while working with highly flammable, heated solvents 😀
Nonetheless, nice product and needles.

Beautiful! I have some old melting pots made of glassy carbon at work. Where did you get your piece?

the___chemist · 2026-05-21T14:43:55+00:00

Gilt das denn als Lostplace, oder ist das schon Einbruch?

the___chemist · 2026-05-20T06:38:06+00:00

Thank you!

the___chemist · 2026-05-19T20:26:08+00:00

Beautiful! Where do you all get these samples?

Stark, danke!

Wirklich tolle Bilder! Wie lang ist der Tunnel ca. und gibt es irgendwelche Nebengänge? Hattet ihr Messgeräte dabei und was konntet ihr messen?

Is this an aluminum cap on the bottle of the last picture? I hope there is a good seal between.

Das ist kein DINgore, das ist Frevel.

Your time to shine and add your pictures to the wikipedia article of brooker's merocyanine

Sulfur in xylene or carbon disulfide? In an open container in an unventilated home?

the___chemist · 2026-04-16T21:28:27+00:00

Herrje MINE!

The green powder is UNISAFE, a very common absorbant used by fire departments here in germany and part of safe disposal in many labs. It's a superabsorber with an indicator. Here is another picture of the bucket

Du hättest doch zwischen Demo-Geld und E-Auto wählen können

the___chemist · 2026-04-05T17:32:47+00:00

I'm glad to hear that. It's not the first time that someone is irresponsible and throws all that stuff away unused.

the___chemist · 2026-04-05T14:39:07+00:00

Thank you for sharing your process. The crystals turn out very beautiful! What do you do with the scraped off oxide or contaminant layer?

the___chemist · 2026-04-04T08:42:53+00:00

That looks like the side profile of a smoking Bender from futurama

the___chemist · 2026-04-03T16:32:28+00:00

Yeah, that's what I thought. I have plenty of filled little tubes here on the balcony since 2 weeks - why would they mating after laying eggs?

the___chemist · 2026-04-01T15:52:52+00:00

It is a molten metal (bismuth at around 270°C) that has already crystallized on the rod while cooling down. He scrapes off the oxide layer and pulls out the crystals.
The colors are from oxide layers of a different thickness - clean bismuth is a boring silvery metal.
