@Delta Prime - Used to have some cooking skills but since my girlfriend is a Cordon Bleu, i lost it. Anyway, what's so absurd? if rf traverses walls and xrays traveses flesh why shouldn't ir travers parchment? More seriously, i found the bags you've been talking about. Will experiment coming Sun. Also ordered pe sheets of .3 and .5mm from AliExpress but due to war condition, nay not arrive soon.

Absurd is not a bad word neither is ignorance,it should not have a negative connotation. To use those words in a hurtful way does nothing... but increases the arch of a cat's back! It's like transposing an equation, what you do to one side you have to do to the other to solve for a variable which doesn’t seem
to be in the right place. You're piece of parchment is not in the right place..so to speak.
It’s not as simple as just moving stuff around though. There are rules to get to this point, and those rules and their application are necessary.
You yourself noticed that the parchment blocked the detector entirely so...you will never do that again, we will just move on forward not backward.
I'm still learning how to convey information correctly as best as I can honestly. So we will wait for your purchase to arrive and we will go from there. :)
By the way for a little levity.
You say your girlfriend is a cordon bleu she better watch out...for the CIA.
