Ner Mitzvah Round Floating Wicks – 150 Count (Approx.), Cotton Wicks and Cork Disc Holders for Oil Cups - Bonus Wick Removal Tweezers

*update 01/21/2014*I did an unscientific test and determined that 50 ml of canola oil will burn for approximately 12 hours. I think that's a pretty darn good deal.*update 10/21/13*Regarding burn time - this weekend I accidentally left this burning on my desk in a small (5") glass with approximately 2" of olive oil. It burned for over 10 hours. It would have burned longer if the oil level hadn't dropped so low that the wick tipped over and snuffed itself out. (Raising a question in my mind about the reviewer who said that the tipped wick ignited the oil and caused a fire) I was present when the wick tipped over and snuffed, so I saw it happen with my own eyes.Anyway, I don't recommend leaving any burning item unattended, but it was nice to know that these are super safe. I was also pleased with the burn time. The case for emergency lighting gets stronger when you consider the cost, reliability, and safety.One thing I would emphasize to everyone using these is make sure only about 1/3 of the wick is exposed above the silver disk. Any more than that and you risk a sooty flame and/or tipping wick.One more point and then I'll shut up (for now). Only burn these wicks once. When you blow them out and then relight them (even if you increase the exposed wick) the wicks WILL tip over. Once the flame goes out, replace the wick and disc with a fresh one.I LOVE these! I'm not sure what took me so long to discover them - they've been around forever. Put a little olive oil in a small glass, drop in one of these marvelously simple wicks, and presto! an oil lamp. I love the simplicity of the idea. Olive oil lamps have been around longer than candles have (that's a long time). Olive oil burns cleanly, smokelessly, odorlessly, and best of all, snuffs itself if it's knocked over. Keep a box of these wicks handy for power outages - you can use any kind of cooking oil, or liquid paraffin (never never NEVER use kerosene, gasoline, lantern gas, mineral spirits, alcohol, or anything that has a high evaporation rate) for instant emergency lighting. A shot glass (approximately 2.5 oz) of oil should burn for about 6-8 hours.As with any open flame, never leave it unattended, keep it away from flammable upholstery or fabrics, only burn the oil in a fireproof vessel (glass, pottery, metal), and keep away from children and flammable pets.

Great job just what I ordered

I tested these with regular vegetable oil and also canola oil, they burn just fine, and are a good thing to have on hand for emergency power outage situations. For ambience... they're interesting, but I gave them 1 4-star instead of a 5-star because no matter how level the oil is that they float on, they list to the sides of the container. Being that there's only about 1/4" between the flame and the side of the container, I'm concerned that the heat from the flame could crack a glass container. I would have given them a 5-star if the cork plate the wick sits in was larger... I'd like to see this product come in a 2" wide cork plate. Other than that, the wick did its job, and I'd rather have these on hand than not.UPDATE 1/15/2020 IN RESPONSE TO A QUESTION ASKED ABOUT ADDING ESSENTIAL OIL TO THE VEGETABLE OIL:This is an interesting question. Sorry it took me so long to reply back, but I had to experiment with the idea. I pour scented soy candles and make diffuser oils, so I have some hands on experience with things like this. What I did was use a shot glass size container, poured water in 1/2 up, poured in about 1 tablespoon of Canola oil, and about 10 drops of a fragrance oil. There is a very faint scent coming from the candle, but I suspect what you have to do first is to "make" the scented vegetable oil... in other words, you'd have to warm the 2 oils together in order for them to coagulate and become one oil. I haven't tried that (yet) but I suspect about 200 degrees for about 60 seconds would do it, stirring continuously. I would be hesitant to add too much essential oil based on the flammability of it (which the point of heat that causes combustion should be listed on the bottle of your fragrance). I guess I can't post pictures in my answers, so I'll add another review of this with the photo of the test candle.

I bought these after seeing some DIY candles using cooking oil (canola, vegetable, etc). I have already made a few quick candles in the one day since the wicks arrived. They are so pretty & simple to use, & the first one burned 8+ hours. I have some old grapeseed oil (not usable for cooking anymore, due to age) that caused the second candle to have a very 'jumpy', unsteady flame. I mixed in some canola oil & the flame became normal.The wicks are surprisingly small (dime-size) & I was thinking they wouldn't work. I was wrong! I'm having so much fun filling glass containers with vase & aquarium decorations. Because it's all transparent, this little flame lights up the entire container & is very bright. My only gripe is that the wicks move to the edge of the container. Even pushing them back into the center & making sure the wick is straight before putting it in the oil, they still end up moving. But, I will definitely buy these again. They're a great deal.

I purchased these so I could have floating wicks in oil in celebration of Hanukkah. After a few seconds in the oil, the wicks turned sideways, even after I adjusted the wicks to make sure they weren't top heavy. So I doubled up the cork rings. These floated upright for a few minutes, but after I'd lit 5 wicks, they all started tipping over. The oil in the candleholders caught fire, as did the railing on the front of my fireplace mantle and smoke stained the wall behind. I ended up getting burned in the process of trying to put the fires out. I wrote the company who sold them and told them about my experience. They wrote me back to say they were concerned and would contact the company who makes them to try and rectify the problem.

No me gusto mala calidad y solo viene un circulo delgado como papel y la mecha no está no lo recomiendo
