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.
