Some1 recommened i got to therpf.com for this question but I thought I’d try here first. In many movies you glass being shattered Of course to get this on camera it is done on cue. I know they use sugar glass but how do the go about making it shatter?
Hit it with something?
Just to clerify what I’m talking about like when you see some characters walking down a scary hallway and suddenly the windows chatter seemingly on their own
Yeah, same concept hit it with something… If the angle of the camera does not permit easy cover for the object hitting it, then I suspect in todays world a small pyrotechnic charge could be used…

Launch something through it, hit it.
Usually when a window explodes or… anything explodes, there is a hopped off-screen filled with debris to make the explosion more dramatic. It can be filled with fake rubble or more glass shards… kinda cool.
Sugar glass is very old-school and rarely used any more except in breakable glass props (ever notice how oddly a bottle breaks over someone’s head on TV compared to all the times you’ve seen a bottle broken on the sidewalk?) You’d see it in Westerns a lot, where the warping wouldn’t be noticed (sugar glass isn’t very glass like, in terms of seeing through it, etc.)
When you see a window give out or someone jumping through it, it’s often a small charge at the edges of a pane of safety glass - safety glass is designed to essentially get the hell out of the way, and it does that by being designed to shatter into little glass cubes, which are less dangerous, edge wise, than glass-glass - blow the charges with air and debris on one side and you have an explosive window. Blow the window just as a stuntman or object “hits” the window, it looks like they’re going through it (watch, and see how there seems to be no point of impact, then the rest of the glass follows - there’s just an instant spiderweb of fractures across the whole sheet.)
You could do this with regular glass, but there will be blood. Don’t do it. And if you try using a hammer on safety glass, you’ll only get a break at that point (this is why they put charges around the whole pane in movies.)
So, for the low budget crowd, maybe as suggested, a good angle and some quick cuts using sugar glass. Tough call, really. Experiments will definitely be in order.
And now that we’ve gone that far, the only glass piece left is rubber glass - materials vary, but it’s very much like clear tile caulk or sealant, that gets dried into sheets and then torn up into little pieces. Scatter on the floor and people can walk over it barefoot (think Die Hard) without harm. End of the shoot, sweep it up, rinse it off, dry, and store for another day (I got to play with a box of it at the Honey I Shrunk The Kids prop shop, way back when.)
well i found on smoothon.com that they have smash plastic which is the same as sugar glass only it can stand being in the sun. (i believe)
Yeah genuine sugar glass isn’t used much (sticky, attracts bugs, no really all the clear in most cases) as there are better synthetic alternatives aka the smooth on stuff you found…
What’s the price on that stuff like?
$175.11 a gallon
ouch
yeah but to some degree it’s better then just going out and buying bottles becuz if u buy this stuff u can make it into any shape or if u wanted a stain glass window u just use their coloring and this stuff and u get a nice look of going thru a stain blow w/o death or wasting money on something more expensive
