I've got on my kitchen stove (which is turning into a bit of junk pile) A skillet full of sesame seeds drenched in sesame oil, on ultra low heat. (Tap turned to just before when the flame goes out.)

Its been there for about 3 days now, and the oil is drying and connecting the seeds together, I can probably tip it upside down now and it'll stay stuck in the pan.    Ill probably leave it another week there (It takes alot of patience, and a big gas bill, but I dont mind, I'm working things out.) and the oil (As I read on the internet) will go thicker and thicker until it goes hard!

I have another pot there with flour and olive oil (But im doubtful its actually real olive oil, they sell at the supermarket.) and some peanut butter. (But Im also doubtful about that being real peanut oil in the peanut butter.)   and I took a couple of samples off early, and they were like old degraded rubber,  they werent very tough but they had flexibility.

I think that maybe im supposed to use less aggregate and more oil and it might be better.   So hopefully the sesame seeds come out better.

So it takes a long time to do, and u have to fuel it for that long. (Id recommend using electricity not gas, and use a good load of insulation and itll take less power.)  but you might be able to get something tough, water proof and flexible out of just drying oil extending it with an aggregate.

If u insulated it, you probably would need to pump air in and out slowly, cause it needs contact with the atmosphere, because its oxidization,  and it actually gives off a micronic amount of flammable gas as it happens, I think.

I wonder if the seed powder u use should match the oil and it connects better?  I dont know, but I see them use silicone rubber with sand, because it connects better to its own kind.

Makes sense for crystalization too?  But maybe alloys work as well.

Just something I'm doing at the moment,  anyone else know anything about drying oil to get a polymer?

It'll be interesting to see the results for this. Could you just leave it out in the sun during the summer, or would the temperature drop at night mess up the solidifying process?

[MagnusWootton]

Its cool if it works!    Just have to be patient and waste a little electricity and get some good building material out of it,  its win win to me.

About left in the sun. prob It needs direct heat constantly applied.     Just left in the sun, probably wouldn't be enough heat I wouldn't think. It would take alot longer :: That's good enough for evaporation but maybe drying oil needs a bit more constant power.   its about 1000x more work requirement?  It takes some time.

So its still on,   and I will present my results when its ready.  But I need another week!   

It can probably heat up and cool down fine,  but it would take AGES...

[MagnusWootton]

Just a short update,  the sesame seeds seem to be stuck to each other like jelly now, and its definitely stuck to the pot.

so its been about 5 days now?    so i think maybe it could be 2 more weeks on the very low heat,   u really have to wait a long time and be patient.

But I'm pretty sure now that without a decent enough excess of oil at the beginning, it cant stick the aggregate together well enough.

If that's a gas stove, I would forget about the idea right away. I wouldn't want to see you get hurt. If gas leaks out into your whole whole, it can combust to make the whole home explode if there is a spark or a flame is lit (and I know you smoke lol). The more scary part is you are leaving it on for a week, on low, and who know what kind of malfunctiony that could cause... If it's old or cluttered this is even worse. Just switch it for a electric stove, say no to gas.

EDIT: If it is on low, it may leak out without the flame burning it. If it mixes with oxygen, then this sets the conditions for combustion.

Yeh its a little dangerous, but material science comes with inherent risk... 
To forge an indestructable war-hammer, u do have to pay a little cost with your body&soul!!!

I'm planning on making a mould that has acid injected into it with electricity!  so a little gas leak is nothing.
I'm going to be really careful, I watch Cody's Lab on the net, he does dangerous things all the time, and why is he still alive, because he is careful. (Either that or god is saving him hehe).

The cool sciency thing I'm trying to attempt is mixing rock with plastic,  to get a dentable rock, that's imperveous to flame and petrol spills, whilst getting high water resistance, and acid resistance.   It might work,  I dont know how good it is to the environment to mass produce something like that tho.  (But it may be perfectly ok, just dont know.)

It's the same group of materials as bullet proof glass, but possibly not quite that amazing, but still quite good and strong, except instead of silicon oxide, which is glass, and im going to use magnesium oxide. (Which is called Periclase, and its almost as strong, just not quite.)

[MagnusWootton]

Gas is an important part of doing material science, and u have to be careful with it.

Why?  If you force a gas into a liquid, if there is solid there with it the solid dissolves more, because its how you make "ous" acid,  (like carbonous, sulphurous, and chlorinous.)  Even works with gasoline (liquid) and gas (methane), if u want to dissolve plastic, but it doesnt have to be flammable if its a water based gas + acid, (if ur working with rocks.) but it still burns you if it contacts and it can explode, yes.

Just make sure u be careful when you do it, and dont go crazy with PSI,   it happens in industry and factories every day, so if u take the right precautions should be ok.


If you want to generate some poisonous gas,   get a couple of dish washing scours, connect them to a battery and have a solution of epsom salts,   u will make sulphur dioxide and thats what comes out of giant sulphur volcano's. 

If u breathe it in, its not much of a joke however, because itll burn down your wind pipe pretty bad.   So not good idea.    Hopefully no children are reading this...

Why would u generate such a toxic gas?  Because it solutes plaster of paris really nicely into a very hard solid.  and also can make an anhydrous version which is good for making a high temperature kiln with, that doesnt crumble under the temperature stress, but its definitely not for stupid purposes....

why maybe u should keep a secret...

[MagnusWootton]

so no good yet,  so im going to pop it back on upside down so the sticky bit is upturned, turn it up a bit and wait another week.

[MagnusWootton]

I think it works,  but the aggregate wasnt good and I didnt wait long enough.
Takes alot of patience, I bet it takes less time and is safer than the stove, if you blow hot air on it strongly.
Prob could use a perferated mould to let air contact it all sides once its solidified to jelly.

It should work.  Sesame seed oil is $20 a litre,   and it comes out a nice rubbery flexable plastic, good for a bio-inspired robo,
and for artificial rubber organels.

[HS]

Huh, maybe this could be used as a shock absorber/cartilage between the joints of a clay robot. If you dipped a piece of fired clay into the oil, let it dry, re-dip, thin layers like painting a wall, you might be able to build up good joint material.

[MagnusWootton]

That sounds like a good idea,  if only it didnt take so long...

It would take alot longer :: That's good enough for evaporation but maybe drying oil needs a bit more constant power.   its about 1000x more work requirement?  It takes some time.

So I think I see the point, but really using sun heat would make it a lot more exciting, if possible. Cause, how much electricity did it take? Maybe a black metal case, with a glass above it, would be enough to heat it? Now if you need constant heat, even during the night, that'd be more complex to setup.

This, and wood.

[MagnusWootton]

Yeh solar ovens are really good, especially if your in a hot climate, i bet the oil would even boil! so best be careful and dont make it too efficient maybe!


Yes Sorry HS I didnt think of this.   this would go really well.



I think if you injected it with about 50 psis worth of pure oxygen, (enough for it to fully polymerize) that would go really good.     But be careful when you open the valve to let it go, because it would all be gas&oxygen mix coming out,  but I bet ud be perfectly fine, if the psi was only 50 or so.

Then that actually might dry out really quick, if it was summer.   (Like maybe 1 week?)
