@@dominiksaworski8509 now it reads smooth on outside. If the tape works by filling the rough side, having the smooth side out won't allow outsiders to tape the rough side.
I work at a glass factory! This is actually called Velour Glass, and once we cut it, and then wash the cutting oil off, it's completely see through when wet! We get it somewhat often. The most common thicknesses we get are 1/4" and 3/8" (3/8" being more for shower doors, and 1/4" being more for random uses) Great video!
@@Durttar695 it would either have to be outside (because the inside would get wet), or the frosted side is sandwiched into a laminate (more likely because it would be easier to clean).
@@misturchips No. They come in GIANT sheets (196"x216") of pre-coated velour glass. Only one side is coated, as coating both sides are extremely difficult to do at the original facility, and, I believe, it would be ruined in the oven by baking the coating onto the oven rolls instead of onto the glass.
Window guy here. You can completely avoid this by getting double paned glass. The outside pane is regular vision glass, the inside pane is the obscure, with the jagged edge facing outwards toward that first pane. The 2 panes are sealed together along the outside and with argon gas between the glass. Now you have obscurity and greatly reduced UV light coming through, only regular light, which also helps keep the room temp controlled.
@Crocoroar yes, the way these windows are made, the entire glass package can be removed and replaced, pretty easily to if you know how. Also the only way to let the argon out is to break the glass
We had this installed on a shower in a house we're building. I got quite the surprise when I tested the water fixtures and body jets. We'll just say that when that glass is wet, the privacy is...not so private. This normally wouldnt be a big deal, but it was a 8' x12' panel to an interior courtyard directly across from the kitchen with a wall of clear glass. I wanted to just let it play out with the owner, but my conscience got the best of me. We fixed it by havin another layer of privacy glass laminated to the original. Edit: For the comments stating it was "installed the wrong way," no it wasn't. It's an 8 foot wide, 12 foot tall structurally rated panel, 5/8" laminated glass pane on the exterior that is required to be there so it doesnt break under wind loads. Everything else is explained in responses to comments.
@@Bluhbear No, the outside panel is required to be 5/8" laminated glass to meet structural specs, So the exterior layer is the smooth side. I wish it would have been that simple. 12 ft tall, 8 ft wide panel with zero interior supports. I was the engineer for the project, not the installer. I'll give the benefit of the doubt to the glass manufacturer and installer that they knew what they were doing. The issue I believe was that the glass company wasn't advised it was for a shower or they would gone a different direction, but it was cheaper and faster to modify than wait 6 months on a new custom panel. Easy mistake when dealing with a 15k sq ft home and lots of glass.
That's really cool but can be prevented by having the rough side on the opposite side of the people trying to look through so the tape can't contact the rough surface on the other side, also you could just sandwich the private glass between 2 regular glass pains to make the rough surface untouchable without removing one layer of glass put both methods together and you have a pretty private solution to this work around and most future ones not using light reconstruction systems.
Just switching the side doesn't help when it's on showers (the most common use of privacy glass) because water also unobscures the glass. But sandwiching it would work, the glass just gets really thick and chatters if you don't put space between the layers, so it has to be even thicker.
OMG YES! I've seen this "hack" on TV when I was a little child but never got to test it, so over time I began to wonder if I had actually seen it or not. Thanks for confirming that my memory was correct!
You're probably remembering the "I Spy" TV series with Bill Cosby and Robert Culp. Cosby's character puts scotch tape on a door's frosted glass window so they can see through it.
We do something similar in film scanning to see past scratches in the emulsion. We basically dip the film in a fluid that has the same index of refraction as the film, and then we can scan it Its called wet gate scanning
There's a very specific triangular shape that can make and object not even visible but an object farther behind it visible. Pretty cool stuff glass or crystal can do.
For those who are commenting that you need to put the rough side inside, if u put it inside, water from the shower that splashes onto the glass will fill in those gaps making it useless.
Or in reality it's 2 sheets of different patterned single sided rough sides with both rough sides in the middle then sealed to become 1 pane so all scenarios aren't possible
if water undoes that effect on an IG unit (2 or 3 pieces in a frame) the window was built incorrectly. ive worked in the window fabrication business, and we are supposed to put the rough side on the inside of the window. it would be a good idea if the other pane is coated to check that the coating is not on the outside, because it again is meant to go on the inside. there are tons of coating testers available, all you need is a light, wires, and a battery, cause plain glass doesnt conduct but the coatings do
Hair spray works too, or at least certain kinds. Spray down a few coats evenly letting it dry between coats, then spray down the palm of your hand and buff it to a mirror finish by rubbing it in tight circles.
this answers my question actually, i see a lot of bottles that use this kind of material and usually people would put stickers on it the stickers would also have clear outlines/borders and that part always makes the tumbler see through its fascinating really.
I was in a very expensive motorhome one day and it had all the finest furnishings. Granite counter tops (could very well have been synthetic not sure). There was a shower that had a glass door and was set in a corner with the door sitting at a 45 degree angle across the front of the shower. It looked just like a regular see through glass door but if you flipped a switch the glass became completely opaque. Thought that was pretty cool.
I believe the same thing would happen if you polish the glass. In some car detailing, to fix yellow headlights you would sand the lenses down progressively until the yellow film comes off and the headlight gets very unclear and foggy due to how scratched up the lense is from all the sanding. Then you polish the lense thoroughly and evenly and it becomes as clear as it was when it was new. Then you put a uv protective coating over it to make sure it doesn't yellow again, and some people will even put a ceramic coating over it to make it even clearer and repel water a lot easier. So, just get some polish and a hand polishing pad and you'll clear the glass right up.
@CrunchLabs didja know if you have one sided mirrors (one side is a mirror and the other is a window) putting another one sided mirror up against it allows you to see through it. Figured this out while looking at a fish tank (designed to allow people to see through the glass to the other side, but to keep the fish from seeing out of it) in a chemistry room
oh thats really cool! i used to work at spirit halloween that used to be a pharmacy. the back office had privacy glass on it but we crudely taped a sign to it. you could see thru the tape into the office & i always wondered how that worked!
You can also spray alcohol on it or the liquid from a can of air, Also the liquid from a can of air can let you look into an envelope without opening it.
that's why they're installed double paned with the etched sides against one another. you'll only find single panes in something like office space dividers where it's more for aesthetics than actual privacy. it's a fun grade school science demonstration anyway.
I actually saw this trick in one of the episode of detective conan. Heiji and conan explain how the clear tape can make us see through that type of glass because the culprit is looking outside while in the toilet.
We use this in phone repair shops when doing back glass repairs on iPhones with a laser machine. The backglass is speckled and the laser refracts and loses focus and won’t burn the paint layer unless we had tape to make it a “smooth” surface again!
This only works with milk jars that have a corresponding surface. There are also some that are made like this throughout or where a cloudy liquid has been added. However, there is also private glass that simply has a film stuck to it that can be easily removed.
Water on the etched surface side will do the same thing and as a bonus while it's wet you can see even better though it then the tape as water will fill the etching more evenly. 🙌🏼👐🏼 THE MORE YOU KNOW!👐🏼🙌🏼
I work with wood, and sometimes epoxy resin. When you sand epoxy it becomes foggy/white. But when you pour some more on the sanded area, then it again becomes transparent
I think an easier way would be to capture an image using wavelengths that are either unaffected by the glass or only minimally affected, to estimate the edges of the objects. Then, a custom AI model could be used to apply colors to the image based on the detected edges and an image of the visible spectrum.
Do you know that the reality we see is actually a projection that our brain creates, i.e. assumes based on our experience. And he does it to make his job easier, it's the same with hearing. Mostly interesting topic.
No matter what you take, it needs to - be soft enough to actually get deep into the grooves. - have a flat surface on the outside. - have the same refractive index.
The cool thing is, this is also exactly the reason why you need to apply coating to epoxy resin after sanding. Very cool to see this concept apply to other transparent surfaces!
We did this in school about twenty years ago. We had this glass from our classroom to the corridor. When we were doing something forbidden we could see when the teacher would enter the classroom and stop our mischief
I used to be a screen printer, and noticed that frosted glass could be made clear again by printing a clear glossy varnish on it. Had several customers who loved the idea and had me do it on their bottles. The one problem was that in photoshoots it was impossible to get that print to show up without fudging it. Was a cool little experiment though. Later I fiddled with varnish with a very small amount of color mixed in to make it more visible.
My first thought when he said there needed to be something to fill those gaps, my first thought was tape. I remember seeing something about tape fitting itself in the tiny gaps so it actually sticks.
It's the clear adhesive that fills in the surface irregularities. This only works with frosted glass. It won't work with other types of privacy glass that have (relatively) large texture patterns. Also, some "frosted" glass is done with a plastic film, and this technique may not work on that, either. I've always laughed at showers with frosted single-layer glass, because it doesn't matter which side is textured. Even if it's on the outside, water will condense and make the glass transparent.
Privacy glass is for vehicles. It’s dark tinted and somewhat reflective tempered curved glass. The glass you are working with is a flat commercial/residential glass that is frosted or sand blasted or obscure or acid etched. What you call it pretty much depends on how long you have been in the glass industry.
Specifically this pattern is called Satin glass. The coating would be on the inside of a double glazed unit because it you touch it it permanently stains so this wouldn't work unless you smash the window and sellotape it back together 😅
I did this when i was kid to see through people passing by, I didn't realise the physics back then... And now i really appreciate that the rugged surface is towards the room
Only works if you can apply the tape to the "rough" side of the privacy glass. And the tape trick can be defeated by making the glass rough on both sides.
You can also put water on the side that’s rough to see through it pretty alright. It’s sand blasted that’s why it’s rough and not see through. “Frosted” is a better term. I work in the glass industry
This also works for super scratched up in graffiti plexiglass windows I used to use this tape method in juvie/jail in order to look out the window sometimes if you also have access to some type of oil that works in a super contemporary method that also works is water
I am a big fan of your channel. Does it work on both sides of the glass? Or do you have to be on the sides with the jagged edges? For that matter are both sides jagged?
Just water or oil would even work, too. And also: This works only on the frosted side, which is usually on the inside. The outside surface is frequently smooth already, so applying anything from the outside to look in won't work anyway....
This marina i work around has bathrooms with this glass and all the time people get water splashes or their hands drip water on the glass so there’s always tiny clear spots that are see thru .
Its not exactly privacy glass, but its a similar distorting device for glass that is actually easier to see through with polarizing lenses in glasses and the likes.
In Germany it is usually only the middle layer of glass that is privacy glass, the outside layer and inside later are both regular glass, so you wouldn't be able to do this trick.
Scotch tape. Just put a piece of scotch tape on it. The clear kind. The adhesive in the tape is also clear, and settles into the "rough" surface, creating a clean lens effect.
You could try LOCA glue that is used for gluing phones together. LOCA is clear, needs to be set with a UV light source and has the same refractive index as glass.
At work, when i clean office windows with that glass, the water also makes it see-through
That’s what I thought he was gonna do. Same effect, different medium.
exactly, worth noting most clear liquids(even oil) would work.
So it’s pretty bad that they use this stuff in bathrooms then?

Privacy glass is mainly known as frosted glass this is actually the first time I heard someone call it privacy glass.
Me too everywhere I hear frosted
In our country it is called sandblasted glass,because that effect is obtained through the sandblasting process.
It's called privacy glass when the intention is to create privacy. In other cases it's normally just called frosted glass, yeah.
Also works for sandblasting shield when they get worn and cloudy. Works extra well if you spray with alcohol first.
I usually put clear polish top coat to do this as well and it’ll stay without looking muffled like tape does

In some cases, clear forms of oil also work.
Same as fogged lenses on headlights I prepare. I sand them amd leave them scuffed then spray with clear uv spray and it becomes clear...
Tape resolves the refraction? Nice.
I am a big fan of your channel. Does it work on both sides of the glass? Or do you have to be on the sides with the jagged edges? For that matter are both sides jagged?
You can also spray it with clear coat
Grape jelly works too. Pretty much anything you can use that is see through. (Yes grape jelly is see through when you spread it on a window)
It can only be done if the refractive index of the tape is same as of the glass
Just water or oil would even work, too. And also: This works only on the frosted side, which is usually on the inside. The outside surface is frequently smooth already, so applying anything from the outside to look in won't work anyway....
i have that same fiber optic cable lmao
it’s to a starlight headliner (which looks amazing in my ‘92 sc400)
This marina i work around has bathrooms with this glass and all the time people get water splashes or their hands drip water on the glass so there’s always tiny clear spots that are see thru .
Very clever solution, I was expecting oil but possibly that would make for quite a blurry view
The glass door and the glass wall at my shower is made of privacy glass. When I pour water it also makes me able to see through.
Privacy glass is acid etched on one side. A quick method of ensuring privacy is to acid etch the smooth side. It harder to keep clean though.
Its not exactly privacy glass, but its a similar distorting device for glass that is actually easier to see through with polarizing lenses in glasses and the likes.
In Germany it is usually only the middle layer of glass that is privacy glass, the outside layer and inside later are both regular glass, so you wouldn't be able to do this trick.
you can do the same with water spray bottle... thats why the jagged side is on the outside of the shower
Scotch tape.
Just put a piece of scotch tape on it. The clear kind. The adhesive in the tape is also clear, and settles into the "rough" surface, creating a clean lens effect.
*Is it translucent or opaque?*
It's opaque
Wouldn't deflected be more so mirrors? Isn't refracted more appropriate to use in this case?
I'm so impressed as I had no idea of this!
I had an 03' chevrolet Suburban that had jazzed over head lights and I use packing tape to make them look brand new
Oil works fine too. Or water.
Privacy glass might work like ground glass on a camera. You could probably see past the privacy glass if theres a lens on the opposite side.
I already knew that but still I liked the video and it's nice explanation. You could also make it wet or even apply some transparent glue!
You can also use petroleum jelly and Saran Wrap
Acid etched glass always has smooth to the weather side.
In a shower it's the opposite.
You could try LOCA glue that is used for gluing phones together. LOCA is clear, needs to be set with a UV light source and has the same refractive index as glass.
You can just use water to see through. But this only works on the rough side not the flat.
Just put the jagged side of the glass on the inside of the private area, or on both sides?
if you fill in it's bumps with something you can see though it
Just saying it is refraction because reflection is much different. Reflection is light bouncing back towards you
