Candle making and tins?

[thawedtime.livejournal.com]

Building on my whole "tea" theme for gift baskets this Christmas, I made a candle out of an old tin.

One thing crossed my mind, however..



How big a risk am I taking by pouring candle wax into a twinings earl grey tea tin? Is there someway the whole thing could catch fire through just normal burning?

Thank you for any help!
