I use all glass but I am now moving a little into stainless and rebuilding my own.

Essentially ditto. I just don't use plastic anymore for vaping. Less muss and fuss. Glass , glass, glass!
However, for my juice storage I could give a hoot.
There's several really amazing and easy to use tanks now that are all glass.
While plastics MAY be safe, depending on juice, I won't trust it anymore... here's the chemical explanation:
everyday chemistry - Chemically Speaking, What's Bad About Inhaling Plastics? - Chemistry Stack Exchange
Also... they say that certain plastics are safer than others... but is it safe, or is it just not melting into puddles? I have read over the years that inhaling plastics can result in cancer, brain damage, hormonal disruption. A glass tank can last forever with minimal care, to save $5, I can't see the risks as worth it... just my 2 cents
.
I'm using Aspire Ego-T S, which are glass and metal, they are WONDERFUL and really cheap too. You can find them everywhere, but here's a pix: Aspire ET-S Bottom Dual Coil (BDC) Clearomizer
For larger batteries, you can try Vivi Nova, which use the exact same heads as the EgoT-S:
SmokTech Pyrex 3.5ml ViVi Nova Tank
And for a much better vape than Protank, here's Davide... uses the exact same heads as the above 2 (also Aspire):
Anyvape Davide Glassomizer BCC 3.0ml w/ 2 Coils - CLEAR [gv-AnyVapeDavide-CLEAR] - $18.95 : GotVapes.com, E-cigarette Supplies - Atomizers Cartomizers Mods Juice and more
I got mine in a forum Coop, the above are only for the photos and a rough idea of what they are... but if you haven't, you might want to try them, they are fantastic heads.

That's certainly your perogative. However, don't judge those who wish to do so. The chemical reaction of polycarbonate when exposed to certain flavorings has little to do with what it will do to the human body.
This does not mean that these flavors are harmful to vape. The process is a similar chemical reaction to what happens when you pour soda on the corrosion on your car's battery terminal to dissolve it. Obviously, soda does not have the same reaction to your body.
How to Dissolve the Corrosion from Your Car Battery Using Coke
Everyone should make the decision for themselves whether or not to vape these flavors.
Other thing is... how do you know that they are going to eat plastic BEFORE you buy them? Not every flavor/juice you buy come with warning labels about plastic eating.
.
The exception to the rule might be true cinnamon flavors. I'm not saying judge anybody for liking it. I have a sweet spot for cinnamon. People should know however to take it easy on cinnamon as it's documented it can be a harsher irritant to the lungs and throat than other flavors.
Because polypropylene and polyethylene don't crack, and they are actually used in storing caustic materials that will eat away metal and glass.
I can't tell you why people use polycarbonate. Not enough people are aware of the risks..from bpa, not cracking. I'd love to try the iclear30s, but my body is already screwed up enough from being exposed to various chemicals...

I agree with you. Also, there are caustic materials that can eat steel... but what eats glass? The reason laboratories use borosilicate glass (which is delicate and breakable when dropped) is because it is acid/alkali resistant. The only substance I know of that can eat glass is hydrofluoric acid (flouride + sulfuric acid), and you wouldn't even want to be in the same building as that stuff, what it can do to human tissue is beyond horrible.
Plastics on the other hand each have their own solvents... and as most flavors are either made of or chemical replicas of plant essential oils, and plant essential oils EAT plastics (every single kind without exception over years- this I've found out myself the hard way) just from storage, it stands to reason that no plastic is safe over time to store in, let alone inhale.

I was going to mention hydrofluoric acid. A base that can break down glass is sodium hydroxide.. both are stored in polypropylene and polyethylene. I can't think of others. I know hydrofluoric acid will eventually easy through the barrel, but there isn't any evidence that shows chemicals being leached in liquids, like bpa, from polypropylene and polyethylene.
I switched to Pyrex Tanks because I'm leery of the "possible" problem of leeching...after all I did switch to vaping for health reasons and am just trying to cover all bases.
Actually... I store both sodium hydroxide/lye/NaOH and potassium hydroxide (KOH) in glass, and it comes in aluminum cans ... it doesn't affect glass. When you add it to water, you do it in pyrex. It doesn't corrode either in 99.8% pure form. Both sodium and potassium hydroxides really only break down organics and fatty acids, so doesn't have much effect on inert containers.
The hydroflouric acid is a different animal, I think it's the fact that glass is silica oxide that creates the problem, and it's not the acid, it's the flouride that's doing all the reacting. Acid is fine in glass.
I like all the scientific chatter I'm reading as I do come from a science background, however my chemistry skills are not as sharp as they once were. I think its important that all vapers are aware of the concerns using polycarbonate when vaping, and that they can pose some risks to your health, not just your equipment.
I like glass...just don't let your kitten bat your mod onto a tile floor...unless you like picking glass outta your feet and having a bent set up

A little cluttered..
I don't know what you mean by the hydrofluoric acid effect on glass, not being an acidic reaction. What the fluoride is doing can be seen as a PH reaction.
Those two statements contradict don't they? I assume you restict your use of plastic to non-polycarb?
I got Pyrex tank replacement for the Mini Protank 2 for $3.95 (Not inlcuding shipping)
I store my smaller portions of sodium hydroxide in glass tomato sauce jars with metal lids. The reason is the seal is better, humidity will get into the crystals and make it clump. Your link is people trying to store liquid NaOH... which frankly should never be stored because liquid lye is nasty. That said, clearly the theoreticians having that discussion haven't handled much lye or they wouldn't be having such a discussion. While possible to have a reaction between lye and glass, it probably requires a catalyst. Fact is, crystalized NaOH has no effect on glass while stored IN it. I'm a soapmaker, and handled it continuously for over 20 years. Hands on will tell you more, why wonder? Draino is about 97% pure lye (along with roughly 3% impurities). Red Devil is purer, but whatever your grocery store sells will show you. Buy a bottle and pour it into a clean DRY tomato sauce jar and see what happens. (nothing).
*note: NEVER EVER add water to lye... add lye to water only. Dump your experiment down a drain that doesn't flow well... do not get water in the crystals... the chemical reaction will take the temp up 170+ degrees or so. Wear eye protection.
As for the hydroflouric acid, the reason it's a problem is that flouride eats oxides. Glass is primarily SiO2... silicone dioxide. I've only handled tiny amounts of hydroflouric acid, you can buy it for etching soft glass (soda-lime/104 COE glass), but it would take months to years for it to work on borosilicate, so not worth doing
.
Correct because most plastics are not polycarb.
Plastic juice bottles are usually LDPE. Some are HDPE. Plastic syringes, and pipettes, are not made of polycarb.
Like I said, I wouldn't use polycarb for anything related to vaping.
I use plastics for mixing all the time without any issues.
It's like saying 316 stainless steel makes a poor knife blade.
That doesn't mean 440C stainless also makes a poor knife blade, because 440C stainless is a great material for blades.
Those older ce4 systems you couldn't change the atomiser; once the atomiser gunked up stopped working you would have had to throw it away.
Not too bad if you use a stong nic blend and take an occasional puff; but if vapers who like to puff away on tasty stuff would be throwing away clearos every month.
Now that we have reached the point where you can replace the atomisers, it makes sense to build a proper tank with glass and steel; concerned about the thing falling and breaking? Some manufacturer is going make it with a protective rubber layer like how many tools and flashlights are made.
