new varnished tins at CandleScience

[Camay]

Back in January CS sent out a newletter saying their tins are now varnished to protect against rust. Anyone test the new tins with rust-causing FOs? I would love to make rust-free vanilla tins!

Here is the newsletter info:

"We've added a layer of varnish to our line of tins. They don't look any different, but the varnish adds a layer of protection that prevents against the corrosion that can happen over time with certain fragrances."

All US-made candle tins are varnished! We've used them for 9 years. There are other ways to get around the vanilla FOs reacting (rusting.) Carole

How do you know that all US-made tins are varnished? Is it a law? I wonder were CS gets theirs, or if they changed manufacturers back in January.

What are these other ways you speak of, lol?

It wasn't rust in the first place. Vanilla simply discolored the tins a rust color.

Years ago, I coated some with Mod Podge. It didn't help. They still discolored.

There is some sort of corrosion going on to cause the discoloration - don't know if it is an iron oxide or not - but I'd like to avoid it. I do so now by not using vanilla FO in tins.

I was just wondering if anyone tried the new tins, and if there was a difference.

Are we talking about veggie wax here or paraffin? Veggie wax is more acidic...

I have had tins oxidize (and it was rust), but they were OLD, yeah! I have never had one rust within a year of pouring a candle into it, vanilla FO or otherwise.

This has been talked about for 6 yrs. We changed to 6006 from 223 to prevent the reaction. Every now & then the problem resurfaces.

It is not rust, but a reaction between FO, tin, and wax. We just found out that wiping the lip of tin with a tiny bit of the FO would completely take off the ring of discoloration. You may have to do it again after 3 or 4 mos. Carole

Edited to say Candle tins are steel, not tin.

Yep. The voice of reason.

What in the steel tin is reacting? What is the rust-colored discoloration?

I know this isn't a new problem. Off and on it gets talked about. I was wondering if CS had come up with some new spectacular way to solve the problem. But maybe it was just marketing?

[SliverOfWax]

I don't know what it is. It's one big reason why I rarely use tins anymore.

Whatever it is, it builds up and gets gummy, whereas rust will pit and flake, eventually eating right through the metal.

Whatever CandleScience is doing doesn't sound promising. My experiment with Mod Podge failed. If any real testing is done, the candle will have to sit around for quite a long time to know if it's successful. Between doing away with Palm (bless the trees) to some ridiculous green shipping nonsense (bless UPS) to this, I'm starting to wonder about them.

Camay, did you ever get any of the varnished ones to try out? I have had the problem you're referring to with CS tins before (non-varnish), but it was with palm. Whatever it was, it looked like rust and discolored the top area where the wax met the 'tin'. It only did it with certain FO's. I had issues with the fresh bread blend I made as well as a couple of others I tried. Anyways, I'm interested to know if anyone has had issues with the 'rusting' in the varnished tins from CS.
