If you can find one, try and get yourself a ceramic filter, and layer that under a grouping of normal silver screens.
And of course, always watch the proximity of the flame-- all too often a large part of the problem. If none of these options are germane, then just run the sandwich technique and just use the screens you currently have. Works quite well.
(Or, and this is really the best option... just infuse in onto some leaf at even ratio. Easy blastoff.)
The metaphysical comfort--with which, I am suggesting even now, every true tragedy leaves us--that life is at the bottom of things, despite all the changes of appearances, indestructibly powerful and pleasurable--this comfort appears in incarnate clarity in the chorus of the satyrs, a chorus of natural beings who live ineradicably, as it were, behind all civilization and remain eternally the same, despite the changes of generations and of the history of nations.
--Nietzsche
Ontology has it backwards. “This ‘saying to the Other’ — this relationship with the Other as interlocutor, this relation with an existent — precedes all ontology; it is the ultimate relation in Being”
--Levinas
