So as we know silica wick is used for all standard coil heads/tanks that are on the market (Except some newer OCC coils that are being released) but this raised a question for me, why did we even used silica in the first place? As we all know silica is quite dangerous and I'm not 100% sure myself if it's even safe to vape, there's a lot of discussion regarding the safety of it. Why was it used in the first place and not just cotton?
EDIT: Seems this turned a little way unexpected. I am a little bit uneducated on silica but I'm simply aware that crystalline silica is known to be dangerous, I was unsure if the silica wick we use is amorphous or crystalline. While I agree there are pros and cons to silica but many people pointed out that silicosis takes years and years to develop, but regardless there is still a threat, now I'm not saying that it's harmless or harmful, but it's too early to tell currently.

Because it doesn't burnWhy is silica even used?
2:
No; silica is not dangerous.silica is quite dangerous
A lot of ordinary stone and sand is basically silica. Nothing particularly 'dangerous' about it.

That's not so much an issue of the wick material being made from silica; that's more about the wick material remaining intact, and not ending up in your vape to a significant extent.I'm simply aware that crystalline silica is known to be dangerous
That's is why there is interest in the ceramic wicks; a more solid wick; basically you want something that has the wicking ability of a sponge material, but the solidity of stone (and temperature resistance of stone); like some corals for example;
manufacturers producing so-called "OCC" coils doesn't do us any good; we are better off if they ship their products with silica wick- in fact the improvement would be if they used the braided silica instead of the cheap ropetwist version
