Do mason jars absorb UV-C light?After some reading it seems pickling jars/mason jars are made out of tempered glass which is heat resistant but it should allow short wavelengths through.
Let's say i have a water/liquid solution in a jar and i want to sterilize/disinfect it with a UV-C light.The jar and the light source would be in a box which sides are covered with aluminium foil. Would it even work? If so how close would the jar need to be and what kind of light source would be effective at this task?
Also what about using it on different substrates that are in the jar and not liquid?
For example i put pasteurized popcorn in a jar and then expose it to UV-C light,occasionally shaking the jar in the meantime.Would this do anything regarding the remaining bacteria/spores embedded in the pores of the corn? Will these substrates degrade in a meaningful way from a one time exposure?

Also i'm planning to use it for petri dishes made out of polypropylene. Will these degrade (significantly that would negatively impact their usage or even make them unusable) just from a few occasions of exposure to UV-C? Seen some videos of UV-C light used on agar and it seemed to work. Though in case of petri dishes before agar pour i could use hidrogen peroxyde. After the pour though UV-C usage would be ideal to really make sure nothing grows on them before inoculation.

It would be really nice to avoid the usage of a pressure cooker if possible and use only UV-C light for these purposes.
