in the past we’ve had a few videos where
we melted down copper somewhere we
melted aluminum and somewhere we melted
salt and today we’re gonna see what
happens if we try combining some of
these things hey guys I am 8 welcome
back to this centre of science of the
concrete pad to start off with throw
some aluminum into one crucible and some
salt and the other will melt both of
them at the same time and try to pour
them both into one muffin tin and see
start by pouring some aluminum into this
and get mold that’s nice and liquid now
let’s see what happens we’ll be pour in
it looks like the salt is kind of just
floating on the surface of the aluminum
the salt has cooled down the aluminum is
partially cooled down they’re both
pretty liquid I’m going to try same
thing another ingot and I won’t mix this
a bit of salt that spilled out of those
trying to pour already cooled down cool
down as a relative term
it is solidified put that piece of salt
I bet still quite toasty ooh and our
aluminum still is liquid right here so
it’s got solidified salt but liquid
metals still going on that underneath
this salt might still be liquid aluminum
too but I don’t want to break through
the surface of the salt I want to let it
there we go our Lumina has now
solidified at least in that one we’ll
give it a little bit more to cool down
and then we’ll try and pop it out of the
tin and it started sort of moving up at
an angle not sure what’s causing that
might be the bottom of the tin has
warped a little bit alright I think our
salt and our Lumina they’re still very
warm but I think they’re cooled down and
up there they’re quite solid so I’m
gonna see if I can flip this pan over
hmmm this one doesn’t want to come out
so well maybe we’ll come out in pieces
oh there it is
well even though I tried mixing it it
looks like for the most part it’s still
one piece of aluminum at the bottom and
then some slightly mixed up salt and
aluminum on top of that piece on the
bottom and of course this one where I
poured them separate
they’re pretty much separate once this
is completely cooled which it’s still
very hot once it’s all the way cooled
down I might see if I can pull these two
pieces apart alright let’s try this
sold use salt first event aluminum all
right I’ve done aluminum and then salt
and then I tried the same thing and
mixed it up now just to see if I get any
different result I’m gonna pour the salt
pretty sure the aluminum just went right
down through the salt into the tin I bet
it’s gonna end up looking a lot like one
where we didn’t mix it the color of it
really starts to change does it cool
down it’s kind of interesting well we
tried it aluminum let’s try this with
copper which is so much heavier to lift
up with a pair of tongs than aluminum is
oh I think my aluminum was still a
little bit soft yes yes it is kind of
like a paste well I think it was too
eager to get that out of the tin you
just flip that back over let it cool
down on the nice concrete yesterday we
tried melting down the copper ingots to
try and get some molten copper but
despite sitting in the furnace for 45
minutes they wouldn’t melt it’s also
possible if they aren’t pure copper I’m
not entirely sure what they were cast
from they could be an alloy with some
other metals so today we’re gonna try
melting down just some of this copper
pipe there’s a lot more exposed surface
area and should go much faster our
copper is melted and I actually put our
cup of salt in there as well so that
should also be liquid let’s take them
both out of the furnace and see what
happens if we mix them together nice
molten copper down in the bottom of that
cup well it’s pretty neat ponyta cools
down quickly the pipes were sitting over
the edge and some of it had spilled and
so we’ve just got a little puddle of
copper formed at the bottom there copper
here is our salt start by pouring the
copper into the ingot that looks really
cool alright adding some salt 3 2 1 I
think the salt cooled down the copper we
can pour more copper on top of that this
thing’s right through it I guess that’s
not surprising the copper melts at
almost 2,000 degrees Fahrenheit and our
furnace only barely gets above 2000
degrees Fahrenheit the salt melts at
closer to 1500 degrees Fahrenheit and it
started cooling down fairly quickly
after I took it out of the furnace to
the point that I think when I poured the
molten salt on to the molten copper the
he difference was enough that the molten
salt actually cooled down the copper our
our cup didn’t really love being in the
furnace of that temperature either it’s
you can see it’s flaking like mad so
here we have what I believe is now just
completely cooled copper with some still
liquid salt on top of it the salt is
starting to cool down as well you can
see crystallizing on top and it’s just
gonna keep crystallizing until it’s
solid all the way through and then
hopefully we can get this ingot out of
the mold
sometimes our ingots kind of like to
bond to the steel but I’m hoping that
once this one cools down we’ll be able
to get it out just fine
molten copper looks awesome
here’s another piece of copper which
doesn’t look anything like copper right
now because it’s just so covered in
carbon and smoke and stuff but that’s
just copper right there I bet we can
sand that down and maybe even polish it
up bring that color back out he’s now
solidified but of course it’s still
extremely hot so we got to give it some
some of our salt broke out copper still
attached a very different color of salt
so having the copper and it may have
done something to it looks like we kind
that is pretty well attached there I
think we’re starting to have our entire
muffin tin pop out of the whole tray we
might need a new muffin tray probably
about that time whole tray is loose just
need to kind of tear it the rest the way
out and then I’m gonna probably pare it
open if I need to to get the copper out
well I scraped away some salt you can
see the exposed copper underneath it I
think the moral of this story is that
you should always use a new muffin tin
to pour molten copper into because Man
Alive as it’s ticking a lot I don’t know
that a new muffin tin would make it
stick less but I think it would ha well
finally cut the muffin tin off of our
salt and copper block see if I can break
off some more of that you can see
there’s just the exposed copper
underneath it with not a lot of mixing
going on although something turned our
salt very very Brown it’s possible that
was just from being heated up in our
steel cup but we haven’t had anywhere
near that result before so I’m betting
somehow there’s copper mixed into this
salt at least on some level
the salt comes off the copper more
easily than the copper came off the
muffin tin
comparing the aluminum mixed with salt
and the copper mixed with salt is kind
of strange and I don’t know if there’s a
definite correlation but the salt and
aluminum the salt really turns sort of a
grayish white and aluminum is sort of a
grayish white metal whereas with the
copper which is a very orange Brown
metal our salt really took on a brownish
orange color like I said I don’t know
for sure that it’s any of the metal
being mixed into the salt there but it
seems to have picked up some of the
characteristics of it we got some really
cool colors from our copper being melted
down I really like that look that’s
always fun hey guys grant here quick
reminder we’re giving away a Nintendo
switch and Mario Kart 8 there’s a link
down in the description so you can get
your name on the list if that’s not what
you want we’re setting the gift received
as well so you can take it back to the store and get the cash back instead
