Not having used silica (I do have some, just not used it yet!) I have no first hand knowledge but im fairly sure a 15minute boil should suffice

Ps. You dont necessarily burn the wire, just give it a light going over with a blowtorch to burn off the manufacturer's oils etc..

Quick once over to get it glowing shoukd do the trick.. dont heat it for too long..

Will make it less springy too which will help form the coils..

You do not need to boil silica, but if it makes you happy.  Flaming the wire is done to remove elasticity to make coiling easier, no other reason.

Burning and boiling are just to remove grease (or whatever). Otherwise they may taste bad for a while depending on how clean they were to begin with. Silica is burnt rather than boiled because it is quicker. I don't see how doing or not doing either would cause your E1.

I'd think it most likely that Perps is right and the centre wire is now touching the side of the post, but try blowing it out (juice or more commonly water from the last wash can cause a short).

And I don't have a Provari, but is it possible that 1.5 is just too low for yours? Do you have anything else you can try it on?

Next time I'd go for a higher resistance - see if you can cram in 6 turns, or coil round two strands of silica to make it fatter. And rather than cutting the centre wire flush with the post, leave 1mm or so sticking out and fold it into the slot at the base. It gives you just enough to pull it a little tighter if you get the short again.

I said that earlier ^^^^^  if it's a V1 provari, it is too low to use at 4.2!

Whilst I'm happy to put my hands up about the silica, I'm afraid I have to disagree about flaming the wire...

I recoiled both of my rssts last night, both with 0.20 kanthal, both at 1.7ohms (checked using evic as well as multimeter).

Built the first one as usual including flaming the kanthal, put it all together and taste was lovely..

Somehow I forgot to flame the second (daughter interrupted me mid preparation) and thats where it went t*ts up!! Absolutely vile!! 

Didn't even bother to try and vape through it, emptied the tank, re-flamed the 2mm rope, fresh mesh and fresh (flamed) kanthal, re-filled and it was back to brilliance again...

So yes, you do need to flame the wire... That was the difference between a lovely vape and almost puking!!

Well we are going to have to agree to disagree then.  When I don't flame the kanthal it makes no difference to the taste, just the recoiling.  The moment you do a burn to make sure all is OK, you will get rid of anything then.

I don't burn my kanthal either, but maybe it is clean to begin with. Can't do any harm.

It takes the springiness out of the wire, makes coiling a lot easier.

Fair enough

Maybe it's just a case of where it's purchased from..

Thanks Roger My 0.15 isn't too springy anyway, but I'll need to buy some more wire & wick soon and I'm still wondering what to get. I now use evods as well as novas and they need more volts (also an iclear 30, but I assume that'll be the same as a nova double coil).

note for the lurkers - if you don't have a blowtorch, a gas hob works fine, even a gas ciggy lighter at a pinch.

A ciggy lighter is just right for the wire giles  It is surprising how easier the wire becomes to coil.  Stays where you put it instead of trying to take your eye out.

I would have checked for a 'hotspot' as 99% of the time that is what will give you that foul, metallic taste.

I do, painstakingly, every time!!

Each and every coil was glowing evenly. I wouldnt have filled with juice otherwise..

But you can't tell if you have a hotspot until you have put some juice on the coil.  Coils will glow evenly when dry, it's when they are wet that HS show.

And I had none.

Once I realised that something had gone wrong I put it on my drawtube and cranked it up to 5.5v. Not one single hotspot!

Fair enough, but as I said before, I have never had a bad taste from the wire alone (and that is from many sources).
