I don’t believe the glass itself would be able to hold the same (or greater) amount of energy of the detonation products before breaking and
releasing them towards a main charge, though I haven’t done any research into comparing the plastic strain strengths or fracture tolerances of glass
vs aluminum.
Consider that a panel of glass can be broken from one swing of a hammer, whereas that same hammer swing would only dent an aluminum sheet of the same
size &/or weight. The aluminum can just tolerate more plastic strain before critically failing, and thus an aluminum cap would be able to store
more detonation gases/products before expelling them towards a main charge; meaning more energy to be directed at your booster.
And please do not assume that your glass caps would simply be transported or made safely. Catastrophic events usually occur when people think they are
safe and prepared. A suspicious, paranoid, and pessimistic outlook isn’t socially preferable but it is indispensable when dealing with explosives
and their manufacture.

Pardon my ignorance if I’m repeating a past inquiry, but does anyone know of any current transcriptions or general literary archives of
energetic-related YouTube videos? I think transcriptions of some of Dugan’s, DBX Labs, Ex&F, and others’ videos could be very useful if
properly compiled (with important screenshots where needed).
If anyone has already started I’d be glad to help in any way I can, or if not, I was planning on starting myself with Dugan’s recent
‘Detonators’ video just for my own.
Of course the military docs, scientific pubs, and patents are highly regarded (as they should be), but documentation of the amateur experimentation is
in my opinion, just as valuable to the amateur.

May I ask you (members) what type of PIB you use for plastification PETN? Can you describe technic? - cause I'm not sure that it is only enough PIB.
Is it possible to try with PIB32? Or need only PIB150 or PIB200?
What about Silicone oil viscosity 10.000-20.000? Found some patent about it, but not sure about good result - I received not plastic mass, it is more
close to pasta, dough.
Another question: what type of mortar do you use? Porcelain, plastic or wood?
And one more question: is it true that plastic mass will be more high density (as you describe 1.56-1.59) then just pressed PETN (with water, after
drying). Maybe we can receive higher density after pressing with small amount of acetone - or it is much more dangerous then water?

Do you have any other channels on other sites that may have your video's? I seem to recall you having many more video's than what is available on YT.
I'm guessing the ones I'm thinking about have been taken down. Do you have any other sites you post on? Fell free to PM/DM me is you don't want to
post it publicly. Thank you!

I got question about that rubber stripe in gasoline (heptane). How long need to wait to move all PIB from stripe to solution? If I measure
concentration after 5 days - will it be the same after 10 days? Maybe better to remove stripe after some time?

Step 1: After 10 days, remove the strip in gloves and run it between your fingers. Measure the concentration and write it on the jar.
Step 2: Place the used strip in a new jar and add the appropriate amount of heptane for secondary PIB dissolving.
Repeat Step 1 after 10 days.....

Oh..ok ok...now I understand that heptane can accept only some part of PIB. Maybe 7-8%. Am I right?
Maybe better to use bigger amount of heptane to use all PIB in stripe? Did you calculate it?

You can try it. But methode from video is optimal.

Just out of curiosity, has anyone here ever subscribed to the international journal of propellants, explosives and pyrotechnics?
It is quite pricey for just a years subscription and I'm not sure they would even send it to non institutions or organisations.

Some here may still have access via university accounts. I’d recommend asking for specific articles here on SM or on the Ex&F discord. I’ve
only ever used Sci-hub which pulls those PEP articles around 1-1.5yrs after their publication.
In my opinion, none of the Wiley, elsevier, springer, etc. journals are ever worth the prices they ask for. If some hardcover versions were published
that may be enticing, but pdfs are not worth more than $1 per, especially considering how easy they are to pirate and how wealthy those publishers are
anyways.

Thankyou! I just checked out scihub and already found a few papers that I haven't been able to access before by pasting the DOI numbers in to their
search engine. That's a really handy site!
After that, I agree, it wouldn't be worth purchasing unless a sort of hard cover compendium was ever released full of different interesting articles
and papers.
