VELMA21 Posted August 31, 2021 Share Posted August 31, 2021 I never really gave much thought to coffee mug candles, but my mother in law is wanting some for company Christmas gifts this year. Can you use any kind of coffee cup? I’m afraid they would crack or something. Help! Quote Link to comment Share on other sites More sharing options...
Lizzy Posted August 31, 2021 Share Posted August 31, 2021 rule of thumb is if it's dishwasher safe it should be safe for candles camping mugs (enamel ware) make great coffee cup candles too Quote Link to comment Share on other sites More sharing options...
TallTayl Posted August 31, 2021 Share Posted August 31, 2021 I agree with Lizzy. I’m a ceramic artist who prefers stoneware for its ability to handle rapid fluctuations in temperatures and les than perfect handling. Many clay bodies are not forgiving to rapid or uneven temperature variations. Learned that anything ceramic can suffer unnoticed stress cracks that show up when the object is exposed to sudden heat changes. Many ceramic mugs (and glassware) are banged around and don’t show stress until the items fails and the mug suddenly “breaks for no reason”. I would use new versus repurposed/thrifted mugs for this reason. An ASTM test uses hot and cold water cycles. If the mug can remain intact when hot/boiling water is poured into it, then a candle should be fine if wicked well. Candle heat is not an even heat like a dishwasher. The flame concentrates temperature differently around the container throughout the candle’s life. Quote Link to comment Share on other sites More sharing options...
VELMA21 Posted September 3, 2021 Author Share Posted September 3, 2021 I grabbed a few at the dollar store to try out. At first I tried cd10 wicks, and they tunneled. Then cd12 and the flame was sky high with soot everywhere lol! Switched to wooden wicks that I know like the back of my hand, and it’s perfect! The mug isn’t even as hot as coffee after 4 hours burn time. Gonna power burn tomorrow and see what we get. Funny enough, I went to the thrift stores today just to look around. Mugs were $1.99 vs the $1 at Dollar General and Dollar Tree. And they were all really ugly lol! So I’ll definitely stick with new, and likely go the camping mug route. I happened to find these little espresso mugs, and thought they were adorable. They hold close to 2 oz of wax, which I thought was just too cute! I’m gonna burn it tomorrow and see how it does 1 Quote Link to comment Share on other sites More sharing options...

I would think not, since the fragrance oil would make it not food safe??? 1 Quote Link to comment Share on other sites More sharing options...

You will need to look at the IFRA certificate for each fragrance, and determine one by one. Quote Link to comment Share on other sites More sharing options...
