in this video are going to experiment
with melting epsom salts also known as
magnesium sulfate YouTube user Gallus
waken was curious what would happen if
we put Epsom salt in our foundry will it
melt down into a liquid the same way
table salt does here’s what we want to
learn it can we melt Epsom salt in our
furnace and if we pour it out into a
mold
can we cast something out of it Epsom
salt is magnesium sulfate and it’s most
commonly dissolved into water and used
as a mild first aid for things like
sprains or bruises this is also used as
a saline laxative meaning you mix it in
with water it turns it into a salty
water and it helps you go if you’re
stopped up but it is a type of salt and
we’re gonna see if we can get it to melt
down into a liquid similar to the
melting down table salt it’s kind of
bitter I really don’t enjoy that it
doesn’t taste at all like table salt
like none whatsoever it’s not terribly
surprising it’s entirely different
compounds it’s entirely different
chemicals it just happens to look
similar and it is a type of salt but
it’s not table salt but let’s see what
happens when you melt it down can we get
this to turn into a puddle of clear
liquid
[Music]
don’t know why one is blue and one is
green it does look like something is
happening around the edges of the cup so
I’m inclined to think that maybe this is
gonna go somewhere however magnesium
sulfite is supposed to melt at quite a
bit higher of a temperature than table
salt so we are gonna put the lid on and
let it sit for a while and see what
result we get after we look at the
melted Epsom salt I wanted to try
casting it and I was trying to decide on
a good shape and I thought well it’s a
crystal what if we make it look like a
bigger crystal so I took this piece of
wood and I cut it and I sanded it down
to sort of look like a crystal growth
then I fit an eye bolt in the back we’re
going to try and mold this wooden
crystal in some dirt pull it out and
then cast our magnesium sulfate in that
crystal shape our Epsom salt has been in
the foundry for probably 30 maybe 40
minutes at this point and it’s just
starting to liquify however the steel
cup that it’s in is starting to fall
apart the added heat makes it oxidize a
lot faster and it’s possible that the
magnesium sulfate does something to it
as well but I think we’ve started losing
part of the side wall of our steel cup
we’re gonna take a look at what’s
happening inside this thing it’s all
so we’ve got some liquid down there it’s
sort of like a thick liquid but this cup
was solid when it went in and it’s just
now falling to pieces very thin walled
steel cup I’m afraid if we give it any
more time that cup is just gonna
completely going to disintegrate in fact
it might already it might just fall
apart as I try and take it out and
leaving the top off of the foundry
cooled it off enough that whatever
liquid we did have at the bottom of that
cup is just gone by Dawn I mean it’s
Risa Lydda fied I have a crucible that
is now full of a regular table salt and
we’re gonna try and melt it down here
and the reason we didn’t use the
magnesium sulfate in this crucible is
that these crucibles insulate quite a
bit more and since I knew that our
foundry was only barely able to get to
the temperature that melts the Epsom
salt in the first place I didn’t think
it would be able to melt it through this
crucible however the table salt has a
much lower melting point and we should
be able to liquefy it in you
[Music]
cool down turn it back to being mostly
white but it’s still very hot so let’s
lot of steam
[Music]
that’s some weird formations with shapes
that this is turned into on the sides
it’s pretty funky stuff rest in peace
stainless steel measuring cup completely
destroyed the integrity of that steel
cup it’s just gone and here’s our salt
[Music]
to mold our little wooden crystal we’re
gonna mix some water in with this dirt
that I’ve sieved a little bit to get all
the large pebbles out we’re gonna try
and use these two by four pieces of sort
of box to hold it together I’ll press
this in and really press all the I guess
we call it mud but it won’t be quite so
wet as that and we’ll try and make a
mold then pull this out hopefully it
comes out nice and cleanly and we can
pour our salt into that
okay inside that looks pretty good
that’s gonna be our mold see what
happens when we try casting salt into it
oh I believe the force of the salt
hitting the water in the mold broke the
mold apart and we started having our
liquid salt flowing out the bottom I
admit I did have some suspicions that
something like that would happen
[Music]
salt flowing over there right there
there is still some in the mold but I’m
not sure if any of it stayed intact in
there like the shape of the mold might
be completely destroyed I don’t see any
clear exit points though so that could
all just be salt that bubbled over off
the top and ran it might not have broken
out of the mold might have just bubbled
up from the mold
give that a couple minutes to cool down
[Music]
well I wouldn’t say it cast it up very
pretty but we did get in the shape of
the crystal a little bit
attempting to melt epsom salts did not
really work very well we were barely
able to get it to melting temperature
and by the time the heat had caused our
steel cup to oxidize so badly that they
lost all structural integrity and all we
got were some lumps of half-melted salts
melting down the regular table salt we
then tried casting that and it was mixed
results we passed again really wet dirt
and the salt reacted with the moisture
in the dirt unsurprisingly and a lot of
the salt bubbled up out of the dirt and
what didn’t bubble up had a tendency to
stick to the dirt itself so there’s dirt
sort of embedded in the salt there have
been a lot of questions asking whether
or not we can cast salt a lot of people
have commented wanting to see that and
this is by no means a definitive answer
we got a fairly poor result but we did
get a result it took the shape that it
was poured into but it’s so full of air
bubbles and the dirt of the substrate
that was being poured into it’s not a
very good representation but there’s
lots of different things you can cast it
just because it did not work in this one
method doesn’t mean it won’t work at all
and we might want to try some other
methods in the future hmm salt and dirt
what a great mix guys that’s not the end
there’s always more to see that box up
at the top will transport you directly
to our last video you should go check
that out the other box will show you
what YouTube thinks you need to be
watching next and there’s balm in the
middle will subscribe you to the channel
so you never miss out on the fun don’t
forget to ring that Bell and we will see in the next one talk to them
