Shouko Seto : Daddy, Daddy! (0:00:02.54)
Shouko Seto : Look what I got. (0:00:05.65)
Shouko Seto : This one's smooth and slippery. (0:00:08.07)
Shouko Seto : And this one's sparkly! (0:00:10.81)
Shouko Seto : Yeah, I love them! (0:00:22.11)
Shouko Seto : Look! (0:00:25.83)
Shouko Seto : All these rocks are different colors. (0:00:26.83)
Shouko Seto : This one has stripes. (0:00:29.51)
Shouko Seto : And this one's round. (0:00:31.86)
Shouko Seto : We can find a ton here. (0:00:33.59)
Shouko Seto : Wanna look for them with me? (0:00:36.02)
Shouko Seto : Sensei! (0:00:52.06)
Shouko Seto : Look, I found a rock. (0:00:53.82)
Shouko Seto : A really pretty one. (0:00:56.59)
Shouko Seto : Huh? (0:01:06.61)
Shouko Seto : Wait! Sensei. (0:01:08.21)
Shouko Seto : Sensei! (0:01:10.30)
Shouko Seto : Mommy, is it weird to like rocks? (0:01:21.88)
Shouko Seto : Really? (0:01:33.61)
Shouko Seto : Yeah... (0:01:45.82)
Shouko Seto : Okay! (0:01:49.66)
Shouko Seto : Daddy! (0:02:10.03)
Shouko Seto : Okay, I'm coming. (0:03:02.96)
Shouko Seto : It's exams week. (0:04:46.19)
Shouko Seto : Really? I'm fine. (0:04:50.17)
Shouko Seto : It's okay. I have stuff to do. (0:04:58.08)
Shouko Seto : I'm off. (0:05:07.72)
Aoi Kasamaru : Finally! We're done! (0:05:31.69)
Aoi Kasamaru : Ready, Ruri? (0:05:33.98)
Aoi Kasamaru : Let's head to the beach! (0:05:35.63)
Ruri Tanigawa : Hey! (0:05:37.45)
Aoi Kasamaru : Quit dragging your feet. (0:05:38.40)
Ruri Tanigawa : I'm so exhausted. (0:05:39.70)
Ruri Tanigawa : Man, this is the life. (0:06:00.74)
Aoi Kasamaru : Told ya it'd be fun. (0:06:03.72)
Ruri Tanigawa : Sure, but it's a bit far to come after school. (0:06:05.62)
Aoi Kasamaru : Who cares? We're done with exams! (0:06:09.13)
Ruri Tanigawa : Ugh. Don't remind me about that! (0:06:11.98)
Aoi Kasamaru : Yeah, wait up! (0:06:19.86)
Ruri Tanigawa : What's this? (0:06:32.56)
Ruri Tanigawa : It's so blue and pretty. (0:06:34.62)
Ruri Tanigawa : Hey guys! Take a look... at... (0:06:37.08)
Ruri Tanigawa : Maybe it's agate. (0:06:45.80)
Ruri Tanigawa : Or what's it called without bands?
Chalcedony?
(0:06:47.12)
Ruri Tanigawa : I'll ask Nagi-san when I get home. (0:06:50.27)
Shouko Seto : Tanigawa-san? (0:06:52.93)
Ruri Tanigawa : Oh. Hey, Seto-san! (0:06:54.72)
Shouko Seto : Short time no see. (0:06:56.70)
Ruri Tanigawa : What's up? Wanna swim with us? (0:06:57.94)
Shouko Seto : No thanks. (0:07:00.32)
Shouko Seto : Um, what's that you're holding? (0:07:02.32)
Ruri Tanigawa : Oh, this? (0:07:05.16)
Ruri Tanigawa : I just found it! Cool, huh? (0:07:07.48)
Ruri Tanigawa : It's a blue gem. Could be worth something! (0:07:10.23)
Shouko Seto : It's glass. (0:07:12.75)
Ruri Tanigawa : Huh? (0:07:14.16)
Shouko Seto : It's a glass fragment from a bottle
or something, not a gem.
(0:07:14.92)
Ruri Tanigawa : B-But there're minerals like agate
that you can find on the beach.
(0:07:18.48)
Shouko Seto : Genuine blue agate isn't transparent like that. (0:07:22.71)
Shouko Seto : That's glass waste, no doubt about it. (0:07:27.49)
Shouko Seto : It's virtually worthless. (0:07:30.64)
Shouko Seto : Trust me, I've searched
this beach up and down.
(0:07:32.68)
Ruri Tanigawa : Searched...? (0:07:38.23)
Aoi Kasamaru : What's up? Was that Seto just now? (0:07:41.36)
Ruri Tanigawa : Nagi-san! (0:07:44.80)
Ruri Tanigawa : I found this at the beach. (0:07:45.86)
Ruri Tanigawa : Could it be anything other than glass? (0:07:47.38)
Nagi Arato : That's an odd question. (0:07:50.59)
Nagi Arato : Looks like sea glass. (0:07:53.03)
Ruri Tanigawa : Is that a gem?! (0:07:54.56)
Nagi Arato : Nope, it's glass. (0:07:56.66)
Ruri Tanigawa : Ugh, that was misleading! (0:07:59.50)
Nagi Arato : It's a fragment of man-made glass, for sure. (0:08:01.21)
Nagi Arato : Maybe from a bottle or something. (0:08:04.04)
Ruri Tanigawa : So there's zero chance it's something else? (0:08:05.70)
Nagi Arato : Why? Does it have to be? (0:08:08.56)
Ruri Tanigawa : It doesn't have to be, but... (0:08:10.30)
Nagi Arato : So that's why. (0:08:15.39)
Nagi Arato : A girl from class told you
the same thing, huh?
(0:08:16.73)
Ruri Tanigawa : She told me it was worthless garbage. (0:08:19.30)
Ruri Tanigawa : I guess she looks for stuff along that beach. (0:08:22.14)
Nagi Arato : You mean she collects minerals, too? (0:08:24.65)
Youko Imari : Hey, if you ask me, that isn't just glass. (0:08:28.43)
Ruri Tanigawa : Really?! (0:08:33.57)
Ruri Tanigawa : So it's something else?! (0:08:34.62)
Youko Imari : U-Um, well it's definitely glass, but... (0:08:36.35)
Youko Imari : Ahem. (0:08:38.63)
Youko Imari : My point is that it's not worthless. (0:08:40.42)
Ruri Tanigawa : Huh? (0:08:46.11)
Youko Imari : Okay, you two. (0:08:56.06)
Youko Imari : Got your gear? (0:08:58.02)
Youko Imari : All right, let's go! (0:09:00.19)
Ruri Tanigawa : It's cool to have Imari-san
taking the lead for a change.
(0:09:02.26)
Nagi Arato : Yeah, let's see what she has in store. (0:09:05.29)
Youko Imari : Sea glass has its own origins, just like rocks. (0:09:08.49)
Youko Imari : We'll look for that first. (0:09:12.47)
Ruri Tanigawa : Like a source site?
Glass waste has deposits?
(0:09:14.31)
Youko Imari : Mmhm! (0:09:17.66)
Youko Imari : Garbage dumps! (0:09:19.12)
Ruri Tanigawa : Hold up! We're dumpster diving? (0:09:22.70)
Youko Imari : Yup. (0:09:24.94)
Ruri Tanigawa : J-Just to check if I'm following... (0:09:26.19)
Ruri Tanigawa : We're not rummaging through
stuff like that , are we?
(0:09:28.41)
Ruri Tanigawa : What the—Seto-san?! (0:09:33.23)
Ruri Tanigawa : Wait, I never meant you're garbage! (0:09:34.80)
Nagi Arato : Is that the classmate she was talking about? (0:09:38.65)
Ruri Tanigawa : I promise! It's a misunderstanding! (0:09:38.65)
Youko Imari : Sure looks like it. (0:09:40.83)
Youko Imari : Hi, is it Seto-san? (0:09:42.68)
Youko Imari : Do you know where we could find
a lot of trash around here?
(0:09:44.27)
Shouko Seto : You're looking for trash? (0:09:49.65)
Youko Imari : A rice bowl fragment. (0:09:53.92)
Youko Imari : This looks like a good spot. (0:09:56.27)
Shouko Seto : What are those people doing? (0:09:57.42)
Nagi Arato : It does? (0:09:58.62)
Ruri Tanigawa : Looking for sea glass. (0:09:59.34)
Youko Imari : Yeah! We might find you-know-what! (0:09:59.71)
Shouko Seto : I don't get it. All that work for some trash? (0:10:01.46)
Nagi Arato : Nice. What's you-know-what? (0:10:02.86)
Ruri Tanigawa : O-Oh yeah! (0:10:08.34)
Ruri Tanigawa : I never knew you collected minerals. (0:10:09.74)
Ruri Tanigawa : I do, too— (0:10:12.17)
Youko Imari : Found one! (0:10:13.02)
Youko Imari : Just as I thought. (0:10:14.05)
Nagi Arato : Yeah, that's a nice find. (0:10:16.37)
Shouko Seto : I wonder what she found. (0:10:18.47)
Ruri Tanigawa : Imari-san, whatcha find? (0:10:20.56)
Shouko Seto : H-Hey, wait up. (0:10:22.19)
Ruri Tanigawa : Whoa, so cute! (0:10:24.17)
Ruri Tanigawa : Such a pretty blue bottle! (0:10:26.11)
Ruri Tanigawa : This is the same color as the rock I found. (0:10:29.67)
Ruri Tanigawa : Aww man, turns out it was glass. (0:10:32.35)
Shouko Seto : Is that trash from around here? (0:10:35.74)
Shouko Seto : I've never seen a bottle like it in stores. (0:10:37.98)
Youko Imari : Well, that's no surprise. (0:10:41.05)
Youko Imari : Judging from its form and imperfections,
it's probably close to 100 years old.
(0:10:43.16)
Ruri Tanigawa : 100 years old?! (0:10:48.84)
Ruri Tanigawa : Why would something like that be here? (0:10:50.07)
Youko Imari : It's all based on how people
used to process waste in the past.
(0:10:52.74)
Youko Imari : In the old days, it was common
for people to process their own trash.
(0:10:56.33)
Youko Imari : Over time, the glass waste
drifted into the ocean,
(0:11:00.65)
Youko Imari : broke down, and eventually
washed up on the beach.
(0:11:03.84)
Youko Imari : So when there's a lot of glass or
ceramic pieces like you can find here,
(0:11:07.19)
Youko Imari : that usually indicates there's
an old garbage site nearby.
(0:11:11.28)
Youko Imari : That means there's a better chance
of finding old bottles intact.
(0:11:13.66)
Nagi Arato : This one looks more recent. Or is it old? (0:11:18.27)
Youko Imari : There's no processing
at the base, so it's pretty old.
(0:11:21.70)
Ruri Tanigawa : You can tell by the bottle's base? (0:11:25.35)
Youko Imari : It's called knurling. (0:11:27.42)
Youko Imari : Bottles made after the 1960s usually have (0:11:29.69)
Youko Imari : small ridges at the base
from the knurling process.
(0:11:32.40)
Youko Imari : This one must be from
before the mid-Showa era.
(0:11:34.73)
Nagi Arato : The glass waste here must all be pretty old. (0:11:39.54)
Ruri Tanigawa : That's way before I was even born. (0:11:42.14)
Ruri Tanigawa : So it wasn't just any glass piece. (0:11:45.21)
Shouko Seto : You think so?
Maybe if it was in its original form.
(0:11:48.31)
Shouko Seto : Still feels like ordinary glass to me. (0:11:51.64)
Youko Imari : It may seem normal to
find glass along the beach.
(0:11:55.15)
Youko Imari : But just think of just how
uncommon it'd be anywhere else.
(0:11:59.59)
Youko Imari : Glass is a useful material, (0:12:03.72)
Youko Imari : but ever since plastic came along,
it's been used less and less.
(0:12:05.39)
Youko Imari : On top of that, people aren't meant
to process their own garbage like they used to.
(0:12:10.88)
Youko Imari : They may just be glass pieces along the beach. (0:12:16.19)
Youko Imari : But in a way, these are remnants of the past. (0:12:18.66)
Ruri Tanigawa : And they'll eventually break down
until we can hardly see them.
(0:12:22.55)
Nagi Arato : When you put it that way,
they start to feel finite.
(0:12:27.68)
Youko Imari : Not that it's great, since they're
still waste at the end of the day.
(0:12:31.47)
Youko Imari : But all things considered,
they're historical artifacts.
(0:12:36.44)
Youko Imari : One day, we won't be able to
find glass on the beach.
(0:12:40.18)
Shouko Seto : It might be worth keeping one piece... (0:12:49.00)
Youko Imari : Isn't it pretty? (0:12:54.09)
Shouko Seto : Yeah, I guess. (0:13:01.90)
Ruri Tanigawa : I found one! (0:13:12.98)
Ruri Tanigawa : Another pretty shade of blue. (0:13:14.31)
Shouko Seto : And here's a medicine bottle. (0:13:16.07)
Ruri Tanigawa : Hey, isn't it weird
how most of these are blue?
(0:13:18.96)
Ruri Tanigawa : Or should I say greenish blue? (0:13:22.34)
Ruri Tanigawa : I wonder why. (0:13:24.20)
Shouko Seto : Maybe it was popular. (0:13:26.04)
Shouko Seto : Like Ramune soda bottles.
Those are the same color.
(0:13:27.80)
Ruri Tanigawa : Imari-san! (0:13:33.04)
Ruri Tanigawa : Why's there so many blue bottles? (0:13:34.38)
Nagi Arato : You got this one? (0:13:37.21)
Youko Imari : Mhmm. (0:13:38.50)
Youko Imari : It could either be to cut costs or (0:13:40.30)
Youko Imari : because of supply shortages,
depending on the time.
(0:13:42.06)
Youko Imari : Ordinary glass can have
a greenish blue tinge.
(0:13:45.17)
Nagi Arato : Glass is normally blue? (0:13:48.30)
Youko Imari : Yup. Material for glass
turns this color if not—
(0:13:50.09)
Shouko Seto : How? Glass is typically made from silica. (0:13:54.49)
Shouko Seto : Silica is a colorless, sand-like mineral. (0:13:57.65)
Shouko Seto : It should stay colorless
when made into glass.
(0:14:00.14)
Shouko Seto : At the very least,
it shouldn't turn blue on its own.
(0:14:02.48)
Shouko Seto : Is that wrong? (0:14:06.32)
Shouko Seto : I mean, that's what the book said... (0:14:07.56)
Youko Imari : Seto-san, I can tell you've been studying. (0:14:11.10)
Youko Imari : You're right, silica is
a raw material for glass.
(0:14:13.61)
Youko Imari : But like any other sand found in nature, (0:14:17.77)
Youko Imari : we can't forget the presence of impurities. (0:14:20.22)
Youko Imari : The most common impurity
in silica is iron oxide.
(0:14:23.15)
Youko Imari : This is what gives glass
a greenish-blue tint.
(0:14:26.46)
Youko Imari : To make it fully colorless, you need
to add ingredients that counteract it.
(0:14:30.51)
Youko Imari : But that's difficult to fully achieve. (0:14:35.20)
Youko Imari : Even the clear glass we see today often has
a faint green-blue tinge along its edges.
(0:14:37.76)
Youko Imari : Did that make sense, Seto-san? (0:14:43.79)
Shouko Seto : Yes, that makes a lot of sense. (0:14:45.57)
Ruri Tanigawa : Nice, another cool bottle! (0:14:50.91)
Ruri Tanigawa : Aw darn it, it's cracked. (0:14:53.43)
Youko Imari : Wow, I've never seen this before. (0:14:56.07)
Youko Imari : It's a bottle for Konpeito sugar candy. (0:14:57.86)
Nagi Arato : You can tell? What about this? (0:14:59.99)
Ruri Tanigawa : Imari-san sure is having fun today. (0:15:04.26)
Shouko Seto : Hey, who are those people anyway? (0:15:06.73)
Ruri Tanigawa : Oh right! (0:15:10.18)
Ruri Tanigawa : The one who looks more
dependable is Nagi Arato.
(0:15:11.61)
Ruri Tanigawa : And the other person is Yoko Imari. (0:15:14.67)
Shouko Seto : Isn't Imari-san the one
who looks more dependable?
(0:15:18.52)
Shouko Seto : Tanigawa-san, I wasn't
asking about their names.
(0:15:21.94)
Ruri Tanigawa : Whoa! This is cool looking! (0:15:24.86)
Shouko Seto : Wh-What is that? (0:15:26.97)
Youko Imari : Senpai! We talked about this— (0:15:29.03)
Shouko Seto : Hey, Imari-san! Imari-san! (0:15:31.53)
Nagi Arato : Go on, they want your help again. (0:15:35.13)
Youko Imari : Coming! What happened this time? (0:15:36.97)
Ruri Tanigawa : Look! It's a rainbow-colored bottle. (0:15:40.51)
Youko Imari : It's silvered glass! (0:15:43.25)
Ruri Tanigawa : Silver? Even though it's rainbow-colored? (0:15:44.97)
Youko Imari : That's its name, but this isn't actual silver. (0:15:47.43)
Shouko Seto : Is this due to impurities, too? (0:15:53.10)
Youko Imari : Nope, the iridescence is
from changes to the glass itself.
(0:15:55.54)
Youko Imari : This type of silvering occurs
when glass weathers underwater.
(0:16:00.71)
Youko Imari : Take for example, when sodium
gradually leaches out of soda glass.
(0:16:04.58)
Youko Imari : The affected surface changes and
forms a thin film of different material.
(0:16:09.66)
Youko Imari : When white light hits the film,
some of the light reflects off the surface,
(0:16:17.55)
Youko Imari : while others pass through
and reflect underneath,
(0:16:22.33)
Youko Imari :
making only certain colors visible.
(0:16:24.81)
Youko Imari : The color depends on the film's thickness. (0:16:27.74)
Youko Imari : Even in the same bottle, the film's thickness can vary, (0:16:31.89)
Youko Imari : which is how it gets its rainbow-like appearance. (0:16:35.59)
Youko Imari : This phenomenon of light waves and color
is called structural color.
(0:16:38.55)
Ruri Tanigawa : So if you keep glass underwater,
it'll eventually look like this?
(0:16:44.15)
Ruri Tanigawa : I should try that sometime! (0:16:47.79)
Youko Imari : This phenomenon doesn't happen overnight. (0:16:49.52)
Youko Imari : I bet that bottle is decades old. (0:16:52.73)
Ruri Tanigawa : Oh yeah, duh. (0:16:56.12)
Ruri Tanigawa : Man-made glass and weathering
from Mother Nature...
(0:16:58.63)
Ruri Tanigawa : Combine both and you get this silvered glass. (0:17:03.26)
Ruri Tanigawa : Makes glass feel special all the more. (0:17:06.71)
Nagi Arato : Since that's all settled... (0:17:09.92)
Nagi Arato : I wouldn't mind finding one myself. (0:17:12.11)
Youko Imari : Can you tell us where you found it? (0:17:14.91)
Ruri Tanigawa : Right over here! (0:17:17.53)
Ruri Tanigawa : Let's all look together! (0:17:18.50)
Ruri Tanigawa : Phew, we found so many. (0:17:59.81)
Nagi Arato : Ready to head home? (0:18:01.87)
Youko Imari : Hang on one minute. (0:18:03.23)
Ruri Tanigawa : Seto-san! Thanks for sticking around today. (0:18:05.77)
Ruri Tanigawa : I had fun looking for glass together! (0:18:07.99)
Shouko Seto : N-No problem. Thanks... (0:18:11.13)
Ruri Tanigawa : We should do it again! (0:18:14.45)
Ruri Tanigawa : Collect minerals, I mean! (0:18:16.01)
Shouko Seto : Sure. (0:18:20.58)
Youko Imari : Seto-san. (0:18:25.32)
Youko Imari : Here, this should keep it from breaking. (0:18:27.30)
Shouko Seto : Thank you. (0:18:29.54)
Shouko Seto : I really learned a lot today. (0:18:31.19)
Shouko Seto : U-Um, are you from a glass studio? (0:18:34.22)
Youko Imari : Huh? (0:18:37.89)
Youko Imari : Oh! Not at all. (0:18:38.95)
Youko Imari : I'm just a student. (0:18:40.46)
Youko Imari : I study mineralogy in college. (0:18:42.16)
Shouko Seto : Really? In college? (0:18:45.16)
Shouko Seto : You study mineralogy in college?! (0:18:48.02)
Ruri Tanigawa : Imari-san, ready to head out? (0:18:51.40)
Youko Imari : Well, I hope to see you around. (0:18:54.50)
Shouko Seto : Wait! (0:18:59.18)
Youko Imari : What is it? (0:19:00.58)
Shouko Seto : U-Um... Well... (0:19:02.38)
Shouko Seto : I-I've always liked minerals. (0:19:05.79)
Shouko Seto : But not many people understand, so... (0:19:11.75)
Shouko Seto : I take it seriously, really. (0:19:16.82)
Shouko Seto : I read a lot of books. (0:19:19.99)
Shouko Seto : And I have my own rocks. (0:19:21.60)
Shouko Seto : They're just from around my
