Breaking glass

[JustANormalLemon]

here, this robot called Blank hit's a window with It's broken arm violently fragmentating It, this feat has been calculated but a Calculation group menber said You can't calculate glass breaking

But the feat has no pircing damage and is done entirely by blunt force, so... why It wouldn't be usable?

Bump

Technically force is needed to break glass, but it's very brittle. Glass has good strength in many ways, but it's not good against impacts. Maybe asking other calc group members for their opinion will get better answers.

thank You

Pretty sure glass is generally inconsistent in how strong it is. I'm also pretty sure it gives room for humans to scale to like street+ which is abysmal. I may be wrong though.

fair enough... that's sad sinse the calc would be street level +

Yeah, glass is not at all a good absorber of energy, that's why it can't be calculated like other materials in terms of frag and v. frag.

Pulv. energy however, is a different story.

Nice to know

What about tempered or ballistic glass? Are those considered as “brittle”? Because they’re strong from what I’ve heard.

Isn't tempered glass made to fragmentate violently at any damage?

Tempered glass is still pretty weak, in all honesty. Just not as weak as ordinary glass. It will still break from a good hit.

Ballistic glass and safety glass are indeed a different matter. Laminated safety glass is designed to hold together even after shattering it, resulting in it needing another few blows to give way. Ballistic glass has layers of gel in it to absorb bullets and stop them, making it actually pretty strong.

I think so. Any time I see tempered glass break it’s always in very little pieces, even in movies

So then glass calculations can only be used ballistic and safety?

I had tempwred glass explode on me once, yes It's made to violently fragmentate at any damage to reduce the cutting damage It's pieces would do

For safety glass you'd be looking at the force required to break the laminate. Keeping in mind security laminate for glass is a thing, designed to force the intruder to hit it four or five times instead of just once as is the case with normal glass.

For a general run-down, there's a general ballpark of how long it takes an intruder to breach different types of glass.

Normal glass - 1 second

Tempered glass - 1 second (a bit harder)

Double glazed glass - 2 or 3 seconds

Safety glass - 5 or 6 seconds

There's a reason why people go for bars, grills and steel mesh on doors and windows rather than just relying on strong glass.

---

Ballistics glass is different, as it is designed to handle bullets which are obviously far stronger than blows. However, most ballistic glass will not stop a bullet at extreme close range. That's lead to criminals in South Africa still being able to kill people through the windows of their cars.

TL;DR: The ballistic glass could probably be measured.

Actually, on a similar subject, the Wiki currently has a calculation for kicking a locked door open in the References for Common Feats page which is being used for several characters and verses, and outside of specific circumstances that calculation would not apply to kicking a door in, as it is a calculation for snapping an average deadbolt. Many doors don't have a proper deadbolt to begin with which is why they can be unlocked with a credit card or a soda bottle, and even if they do have, it usually isn't the deadbolt that gives way, it's the door jamb. Typically that consists of forcing the latch through a couple millimetres of wood and breaking out three or four half-inch screws from the wooden frame. It's almost laughably easy to kick in most doors.

Anyway, I think the main question in OP has been answered. Should we close this thread then?

I do think there's an issue with this feat reference. What should I do aabout that?

Different topic, should make another thread.
