Metal taste from SS mesh wick comes from either the coils shorting aginst the mesh, long coil legs going to posts or not enough oxidizing. If you get it just right it's one of the best vapes to be vaped.
It could be the power of suggestion, but I do feel the scratchy TH when I use my sillica on the first few days of a new coil(I also know for experience that sillica sand blasting material is not safe to breathe).
The cotton will burn or scorch and taste very nasty
Once the cotton is burnt the wick will need to be replaced
You can dry burn with silica wick
Gotta love cyberchondria [wikipedia]
However in your defense, this post does validate that silica might have a problem :

The reason I like the dry burn is because it's a comfort for me to see the coil glow evenly. I know the coil is still good that way. I'm a bit paranoid sometimes so if I try cotton I know I'll be constantly worried that it's running dry.
Ok I tried to edit my above post, but I can't figure out how (and I have done it before?!)
Try a RC store.(Radio Control) Hobby store.Anyone have a clue where to order/get replacement screws ? Already lost one :/. Or knows the size of those screws ?
