Rust & tins

[silkysoycreations]

I was at a craft fair recently and noticed someone selling 100% tin soy candles...all of the tins had rust on them and were very unattractive. First I was surprised they were selling them as it turned me off right away but my question is what are the possible causes for this? I did a search but seemed to come up with rust and tin molds and how to use pam or wd-40 but didn't know if this is the same for tin containers. I'm thinking about using tins for 100% soy but wanted to know first what tin issues I could experience & how to avoid rust on the container. TIA!!

What you're seeing is not rust. FO with high vanilla content will discolor the tins. Other than being unsightly, it doesn't affect the burn or throw.

I noticed it on every tin which were different FOs. So when does this happen...right away, days, weeks, months? Any type tins you can buy with special coating that won't do this?

I've noticed rust on wick sustainers in my votives, especially with vanilla fo's, which discolours the wax around the sustainer a little, but I haven't seen it in my tins at all & some of them are several months old. It seems to me that heavier f.o's & e.o's have this effect on the sustainers but it's not noticable until a few weeks after production.

I have no idea if anything can be done to prevent this but I explain to my customers that it's an effect of the f.o in the wax & doesn't affect the burning at all.
