just wearing my confused face all the time like what am I doing here? Hey guys welcome to Dig it With Raven
we’re doing a very special edition today in the name of virality and to stay
internet relevant, we saw this thing the other night and we thought we should
get off of it before it like gets buried in the next viral thing. What it is, is
the Instagram account named Blossom. I’ve seen it on a food channel on Instagram. It’s been shared everywhere I think it’s gathered over a million views.
And what it is, is it’s this video. The description of this video is literally”
“Brighten up your day with these five surprising hacks!”
it starts off with a broken plate where they tape it together and then they
cover in warm milk leave, it for 2 days and it gets fixed! The
next one is a really tarnished dirty silver thing and then use heinz ketchup.
They’re doing it with their hands! They rub the ketchup in their hands and
they wipe it all over the metal and magically it’s clean! The next one is take a dirty
painting they take a bagel then they just rub this bagel. They cut it in
half they rub it over the painting and apparently like takes off all of the
dirt. It’s funny for us as conservation students because…
so anna is a painting conservation intern here in Hamburg and I’m doing
stone and ceramics so when we both saw these things are like people… really. Couldn’t
believe it like… what?! So it kind of sparks our interests to be like you know what let’s do a
Mythbusters type thing and see if it actually one is it that’s work yeah, but
I want to get to know the science behind it yeah and that’s why we’re wearing our
coats today because you know science. We wanted to take these life hacks kind
of turn them on their head, take them from a conservation standpoint and see
how well they hold up. And then also talk about the implications that these would
have on works of cultural heritage and maybe why not to use it. I’m a little
concerned so we’re going to do some experiments. Hopefully they all turn out.
So the first one we’re going to try is the ceramics.
I actually went looking specifically for things that I would hate so I wouldn’t
feel so bad about subjecting them to these things. The ceramics
conservator in me is very sad about breaking this.
I don’t know if I can do it. The good thing is I can always fix it if this milk
thing does not work out. Pretty good right? Oh my god we’ve got three pieces I
don’t want to break it into a million pieces though. I feel we should be wearing some
protection… yeah I was thinking about it oh it didn’t break! Go like this! It already got a crack here. Perfect yeah yeah I think that’s perfect.
Do we dare do this one now? It actually won’t break guys. There’s a hole
in it now. You know we’ll do we’ll do it as a crack. Okay so we have broken our
pottery. We’re going to put it into these two containers here with some milk and
try it out. First I want to talk to you about the science behind this and why
milk would actually work .So it
actually all has to do with the proteins that are inside of milk.
Milk has casein in it and that is a protein and what it does is
that when it’s heated and then cooled it can actually make some sort of like a
plastic with it and we use Casein I think, I don’t know actually
how to pronounce it. In German it’s Kasay-een. iand that’s how I’ve been
saying it is three months because I’m in Germany. It comes from the latin
word caseous which means cheese. All milk has casein in it but cow’s milk has
about 80 percent or so it has with a lot more casein in it than other milk so it
works a lot better with this kind of binding and we use it with paintings
right. So it used to be a binding agent with paint grounds as a
glue. Yeah, yes. The science behind it is there. So I’m actually quite confident in
this. What my main concern is is that it’s organic and it can be dissolved. If
you’re eating from it.. I’m thinking or if you’re trying to drink a hot thing and
you’re washing it a lot, I feel like it will eventually break down at some point.
So what the milk is going to do is that once we put it inside it’s going to, its
heated right so to expand and the proteins will then kind of like form
some weird cohesion with the ceramics making its own kind of glue. And
in theory it should work. The video showed us that it was magic and you
can’t even see the cracks anymore. I don’t know so we’re going
to wear gloves because we are professionals. We need to make sure that
this is actually quite well put back together so the seams are pretty close.
So I would press it together, do a bunch of tape over it.
We’ve got our piece of ceramic here that’s been taped up and then we have
here our cup. We need to make sure that the milk completely covers the entire
cracked area in order for it to actually get the sciency bit going. Let’s do it
away from the laptop. Well I trust you I don’t trust myself. Oh
do we have enough milk I don’t know. Let’s cover this up now. We’re gonna
leave it aside and we will check in with you guys in two days.
Alright so it is two days later we have waited patiently for this moment.
Here it’s super stinky… oh oh it’s just so gross! I don’t drink milk.
I haven’t had milk in many years and this is just confirming that I probably
will never drink milk ever again. Are you ready?
So just by touching it by lifting it out I could tell it has not actually worked.
That was easy. Yeah, the video lied to us. What about this guy? There’s milk curds
inside the cup. Excellent I actually think it works for the crack.
Here okay the hole…actually you can see the hole. In the video they literally
took it out of the milk, took off the tape, dried it off and then it was
good as new. You couldn’t even see the cracks. I really just think they took a new plate. But the crack itself is actually stabilized.
Before we put it in, you could move the crack and the
crack is now very very stable. I’m feeling like it’s because of the, the
proteins. Yes they probably don’t act as really strong binder, but with a crack I
feel like the the proteins would just kind of fill the space so it was more
stable. So I do think that if you do boil something in the milk and just like if
it’s just slightly cracked to make sure that it doesn’t crack
further and then actually break into pieces… I do think the milk is
actually a good idea for that. If it’s just like a normal pot that you use
every day and not like an artifact or a piece of cultural property or some
antique or something. So what are you using in conservation for glue? For that, if
you want to use it again we just use normal epoxy resins. Alright. It’s not
reversible, it’s food safe, it works really well it dries really quickly. It’s
done in like a day and then we do a little bit of retouching. And that’s what
we would use. Obviously there’s different things for cultural artifacts especially
if you want it to be reversible and it’s not being used every day. I don’t think I
would use this ever again ever again. Just for the smell, it is
nasty. It’s just not good. So that was a first experiment
completed of our myth-busting Instagram challenge. Tune in later this week for
the ketchup and metal polishing, tarnish removing, magic, whatever. If you
