Very interesting setup there Andy. I was surprised to learn the melting point of glass was so high in comparison to aluminum. I'm in for the results and learning experience as usual.

Me too!! But maybe not today. We've got high winds out of the north today, not conducive to pouring hot metal on the north side of my shop. High winds out of the south and I could have poured late in the day but we lost power. Our area wholesaler, KAMO, had a major substation failure and our rural cooperative was without power from 4:00 to just about dark. I decided I wanted good light to be able to video the process. This morning I'm wishing I'd set up some lights and had at it.
Almost...
I'm surprised the glass doesn't shatter upon contact with hot metal. Apparently it does at some point. Both guys I have heard do this say their glass failed, but they don't say when it failed. The metal may stick to the glass too.
I've got a pretty good supply of glass, though, from old windows I've robbed the frames from. I've never had a lot of luck cutting old glass but will give it a try.
The downside of this experiment is that the glass will chill the metal faster than sand so it may not be a true representation of what happens in a closed mold, but it sure didn't seem to chill much in the video.
Maybe the wind will lay down at dawn.

Could you pre-heat the glass Andy, with a blowtorch?

Are there any garbage dumps out that way that have old ovens laying around? The thought being you could re-purpose the glass from the old ovens.
Just a thought.

Awesome if you get that on film. 
I didn't quite pick up when you said glass you meant actual glass. I just thought you were using a reference to waterglass. Still catching up on all the stuff on the other forum.
Thermal shock would be the first reason glass could shatter. Even borosilicate glass will shatter if the temperature in a small area is outside of the range to cope with the sudden expansion or contraction. Preheating will be good, especially this time of the year over there. Next would be to use two sheets if possible. One supporting the other so that if on cracks you'll still see most of the action. Not quite bulletproof but next best thing. Tempered glass is less prone to thermal shock as the annealing process relieves the internal stresses from casting.
Now I'm looking forward to this!!!

I had thought of that, and with your prompting did, but with lots going on I only gained maybe 200F.

That's a great thought. I've been trying to think of good glass supply. I don't know if a Corning Ware baking dish might work.

Thermal shock, from where?
Two sheets might be good.
I did pour today, 51F and strong wind. I moved the glass flask inside on a bucket of sand to get it out of the wind.
Enjoy! Short and sweet.

Freakin' awesome!!!!
That looks like tempered glass which is why it didn't fail immediately from contact with molten aluminium. Got me good... for a second I though it was even going to hold. But it lasted long enough to demonstrate the concept. May be the aluminium sticking to it and shrinking as it was freezing(second reason) as it went from shiny metal to mat just before the glass went.
So awesome... we have to get you a slo-mo camera!

It got me too, I thought I had a pour I could let cool. But I had another flask to pour and went on to pour it and two ingots.
I think I'll try window glass next. It may be the tempered glass exploded where the plain glass may only crack. And you're right, maybe at first contact.

No I didn't know about the slow-speed playback but a greater frame rate would still be awesome. Didn't notice the blob falling on the weir in the basin the first time round.
Looking at it in the slower speed, it appears that the super hot glass to the bottom was competing for expansion with the less hot glass at the top. Which could be why the top exploded out like that.
Still cool!

Actually, it was a 100% success. The goal was to be able to measure the flow rates in the riser and runner and determine whether the metal would splash in the pattern. The fact that I got a good video of it allows me to do all the measurements I want. Would have been nice had the glass not broken but that was fortunately after everything was done. The patterns were just half circles and would just have been remelted anyway. I would like to figure out how to not break the glass, however.
Now I see the iPhone has a slow motion setting so I'll use that next.
I'm wondering if the clamps were holding the glass too tightly, causing a compression failure. I think I'll pour some aluminum on a piece of glass laying on the ground and see if it explodes like that. I loosened the clamps some, but they were still snug.
That's a good idea. This glass was from a quartz light so I figured it might have some temperature capability.

Hooligans? Naw, we live too far from Chicago...
And Nawleans.
Apparently oven glass is just tempered glass, as is fireplace glass and most cookware. However, some 3D printer glass for heated tables is borosilicate and I found some in an unmentionable place for $10 per piece. A little larger than what I have. I ordered two, reasoning I would spend that much driving around looking for scrap oven doors. So within six months they will magically appear at my door. In the meantime I plan on putting my camera behind glass.
I'm glad, I don't like to hurt old men. Or animals. Or innocent women...
Thanks, Mike!
Thanks, Bobby. No, no, a pro does it for money. I'm a rank amateur.

No, nope, you've got it wrong. To be a successful YouTuber you jack your jaws for ten minutes with your face too close to the camera telling the marks (I mean viewers) what they are about to see and how wonderful it is going to be. Big buildup. Then you yell and scream and hoot and holler when the event takes place and post two or three slow motion replays with text and graphics to make it all more interesting. You also need a catchy name like "Random from Nothin".
I was amused, however, that unsuspecting viewers would get a bit of a surprise at the end of an interesting video.

Andy: great video and experiment and hopefully you didn't get hurt. by the sounds of it you might have been expecting the glass to explode?
hope you enjoy your day while I just keep moving stuff and maybe watch a ship or eagle pass by when I stop to rest.
60 degrees and sunny so from 2 feet of snow and freezing a couple weeks ago I'd say our weather has improved a bit. ZERO WIND too!!

Great video, thanks Andy.
Can I subscribe to your Youtube channel, will I get a signed photo and a calf if I do, or a signed calf ?
I cut glass at work and old glass can be more difficult to cut.
I recon that was toughened glass, the way it shattered, maybe try 6mm, or
1/4 plate, as it was in old english. Guster might be onto something with two pieces.

I had to replace a wood stoves glass once. Local glass shop just had oven glass. It took the heat all right but shattered one day about three weeks after the last fire built in it.
I had to special order wood stove glass for it. No problems after that.

How about a photo of a signed calf?
I've got more than two pieces.
I imagine the oven glass was tempered and the stove glass was borosilicate.

Thanks, Shorty. When the glass blew I immediately thought of you. sorry there was no blood.

No, two 3D printer beds.
It was a blast! Filming it was the only way to be able to really see what happened with the metal flow, and to be able to calculate velocities. My goal was to see how the metal flowed compared to the equations which have a big friction factor unknown based on the particular sand and shape runner each person has. I was elated it filled.
Viral videos? Are they contagious? Is there a vaccine?
Hope the little ones enjoyed it.
Thanks for the visits, guys! I've got a lot to post but am out of time tonight.

Welcome to "Casting Journal". OK, so I tend to get focused on one thing.
The metal flow before the glass broke looked pretty good. The riser had a short weir so the metal wouldn't shoot through. I copied that in a full riser.
The drag
The cope
Castings
I decided to try a crucible with a spout, like old school tea pots. Drilled the hole, polished the area around the weld and had at it.
Welded on the spout
And poured with it.
Pouring Spout
It actually works pretty well.

It's a conundrum. I have to put a video on YouTube to post it here.
OK, I'll break news (not wind). I made a cast iron casting today, my first.
It's really hard to work inside on the first warm days of spring.
Pouring spout is a keeper. Sure looks ugly, but so do I.
Sorry, everybody looks for those. At about $500 each, a tractor with bad rear tires is not worth much. I only have my spare tires.

Early this morning the weather was outstanding. I walked around and looked at raw materials for casting iron.
I've got some junk. No, really.
I bought a nice tractor one time from a guy getting a divorce. He threw in five junkers. Like this one, with a ventilated block.
These wheels are not exactly junk, but they seldom if ever break, and each tractor has two. I have fourteen extras.
This is the front bolster. Probably 300# of cast iron there. I have several extras.
Transmission distance piece. The clutch and hydraulic pump were in this. They never go bad, I have a few extras.
Side view. The gearbox on top is a belt pulley drive. It has some value.
Lot of cast iron here.
And I have four junk balers with gearboxes.
I have options!

Continuing with "what I did in my shop today"
Then there's the seven tractors that burned up with my shop in '89. That's been a while. I could rob from them.
I broke a piece out of the ventilated block
And found an ancient pin shackle. Why not make a copy of that?
Also found a tractor wheel clamp which had broken. That's the block piece to the left.
Sawed the clamp in two. That's the break on the right. It sure sawed smoothly and easily.
Filled the holes in the shackle with plaster of paris, and also filled some worn spots. Then molded it in sand.
You see where this is going.

So the first thing is look at the pour. That's some hot stuff, probably 2,500F
Here it is after a little "cooling down period".
Looks kind of like the original.
Sand blasted to clean up.
Then cut it apart. A few defects.
Ground the flashing and drilled some holes. Easy drilling!
A matched pair, almost.
Now for the ugly. I needed a trap to catch gas pockets. And also a pouring basin to keep **** and air out.
But it's my first. Thanks for stopping by!!
