There's a bowl I have with no markings of any kind, made from nothing but metal. How can I tell if it is reactive aluminum or non-reactive stainless steel?
Telling aluminum from stainless steel?

if you don't have a magnet, bang a screwdriver against something metallic and it will give it a slight magnetic charge... then you can quickly test the metal.
Sure they do.
It depend on the composition of the stainless steel whether it's magnetic or not.
Not really sure how to explain it. I would be able to tell if it was aluminum or SS the second I picked it up.
If it is thin and very light, you can be assured it is aluminum.
If it's like a batter mixing bowl, then it is going to be stainless steel. Aluminum is much too soft to be used for something like that, you would end up eating aluminum shavings each time you mixed something up in it.
I don't think I've ever seen an aluminum bowl..
magnets do not stick to my stainless steel mixer bowl.. I checked.

I have a 70 Ft3 steam sterilizer at work made of 316 and 303 Stainless steel.. Magnets do not stick.
This is also one of the points with new fridges. Get one of the nice brushed SS ones and try to stick a magnet to it. It will fall to the floor.......so not a good fridge to get if you have kids and want to stick picks on the fridge.
stainless steel feel a lot more hard and dense... try to knock/tap on the side and get a feel of it.
and yeah, aluminum has a melting point of 1200C, and you can try to test that.

I did just look up some properties of some of the more common SS types...and apparently there are some types of SS that can exhibit some magnetic properties. I've never seen them and our plant works with SS everyday, but then again we don't manufacture magnetic plunger valves.

Like I said, totally depends on the composition.

Yep, (see my post above). You learn something new every day.
Damn wippersnappers...err....old codgers...err, ummm. Eli, how am I to properly attemt to insult you without knowing how old you are!!
Yeah, didn't see it before I posted.Originally posted by: Sundog

I'm 23.
Step 1: Weigh the bowl
Step 2: Submerge the bowl in water and determine the change in volume of the water. This change in volume is equal to the volume of the bowl.
Step 3: Divide the mass of the bowl by its volume. This gives you the density of the bowl.
Step 4: Determine the density of stainless steel and the density of aluminum. These should be available on-line.
Step 5: ...
Step 6: Profit!

Try scribing it with a stainless fork. If it doesn't scratch it, it's stainless. The fork will be able to gouge out aluminum easily.
