Will extreme heat, in an enclosed trailer, while being pulled, cause fragile glass items to break/be more likely to break?
In: Physics
Shouldn’t. As long as the stuff is packed properly to prevent it from bouncing around it should be fine.
If the heating is uneven it might, like half exposed to sunlight half in shade will cause thermal expansion in part of the material.
Extreme heat can definitely make glass more likely to break, especially in an enclosed trailer where it can get super hot. The heat expands the glass, and if it’s fragile, that stress can crack it.
The biggest factor in glass breaking due to heat is thermal shock – i.e., going from hot to cold very quickly, which causes the glass to break because it doesn’t cool 100% evenly and literally pulls itself apart (cracks) as different parts contract at different rates. But as long as you’re not throwing cold water on your hot glass or putting them somewhere extremely cold right out of the trailer, that shouldn’t be an issue.
If you have a lot of glass things stacked together, one of them could crack the others if it expands more/more quickly due to the heat. You should at minimum provide a buffer layer using cloth or crumpled newspaper between items so they aren’t rubbing directly together. Aside from that just make sure it’s packaged in a way that won’t let it bounce around.
