(A) If I use a magnet and the pan or pot is not magnetic is it than stainless for shure?
(B) Are there any alloys which still could be not suitable even if they are stainless?/Or how can I be shure that my equipment is safe.
(C) Is it easy to get the stuff clean afterwards, because I would like to use a pot which I normally use for food?
(D) How to get normal cooking pots really clean, I noticed mine have some chalk or dark residues from cooking in it?

If you're not sure, best buy a new one from a reputable dealer, or borrow one from someone else.

Go to the manufactures website and look for specification details. Or even a google search.
If in doubt use glass preferably somthing pyrexish or similar brand.

To clean your pots and pans, hot water and washing up liquid, any tough food stains let soak for a while
Maybe a scouring sponge.

Why do you need to know if your pot is stainless?

I want to do A/B and I always read, that the pot should be stainless. Hmm actually I could use glassware as well. But I dont want to spend too much extra money, because I already did spend around 300$ for Lab Equipment, chemicals and mimosa hostilis.
I got 2 beakers (2000ml boro 3,3mm), but I'm not shure if I can use them. I heard for cooking u use more the round erlenmeyer glassware. Not that it gets cracks or s.th when cooking. I think round glassware has the advantage that its more resilient to tension and that the evenly distributed, which is better to avoid superheating.

Another question if I would use glassware, I propably would use also an waterbath for cooking. Does this work, if the waterbath has an boiling point of 100 deg. and the mixture as well, or does the waterbath evaporate first? I mean I could use oil, but I read that this is dangerous and oldschcool, because if s.th spills or the glass breaks the waterbath goes crazy


Actually i meant more these kinds of dirt:


The upper one is the ground, Ok in this case it touches just the heating plate but I think it's burned fats ( EDIT: I alread got rid of the dark brown stuff in the center with naphtha and a razorblade. but the light brown stuff near the rims is still there.). Actualy I just postet it because of the number and because I would love to get it nice and shinny

And the lower picture shows I think chalk inside the pot. But this dirts maybe relevant because they get in touch with the solutions. Maybe some citrus acid could be used. But what I mean, maybe the agreesiv iyes or acids solve that stuff and I dont want to get any extra crap into my DMT. The pot tells stainless (is that correct english?), but I want to get shure, that it's not damaged afterwards, because it's my everyday cooking pot and also I dont want some crazy alloy parts into my DMT if that's possible...

Wikiepdia tells me 18/10 is how much Nickel or Chrome is used in the alloy, and that this alloy is not resistent against salts and chlorine. Ok propably it is resistent to alstwater otherwise cooking would be impossible but maybe it's not resistent if you use crazy acid and then get salts when basifiying...

Mason jars aka kilner jars, should do what you need. Google the phrase. These work well in the water baths. The main threat to your regular glass is, sharp increases and decreases in tempreture. That is why it is always nessacery to let your regular glass cool down naturally rather than under a tap, otherwise pop and the bottom may come off

When the water is running low in your water bath top it back up with more water, small amounts each time for when you need, preferablly already hot. You do not need to go mad and use oil or go spend hundereds on glass.

Using the chems you have mentioned can cause reactions with the metal. Perhaps invest in a new one for all your food usage, and use that for your tricks. Always use glass where possible.

To get your metal clean you will need to use metal polish a brand called "autosol" comes to mind there plus some elbow grease. You can always rinse after with washing up liquid etc, when you have polished it to kill/ remove any nasties.

Check out an STB tek if your using MHRB, will save you lots of time and mess.

HiH (hope it helps)

Hmm but that's also bad, because if the solution does react with metal, it also brings impurities to my solution. But it seems a lot of teks use metal stuff, so how to determine which stainless pot is OK. Maybe I only use glassware, as you mentionend, but for the cooking step a pot has the advantage that a lot of solution fits in there.


Yeah I read a lot of disadvantages, that you gain way less and that the result has more impurities. I think I will stick to the A/B. I heard what you save on time with the stb you have to invest later too get it pure or to get the DMt which you didn't get in the first time.

That is a myth ime purer products from A/B than STB with MHRB (only). If any other material then A/B is highly likely needed. But with MHRB stb is totally ok. But the best tek is the tek you are comftable with in your head

Get a larger cooking pot then Im sure you can get large glass casserole pots.

Glass ftw.
