Forrest Posted April 24, 2018 Share Posted April 24, 2018 In my line of work we are all about data, so notes and picture from my test burns are somewhat unsatisfying to me. After giving the matter some thought I realized I should be weighing each candle before and after each burn. From weight and time data I can calculate a burn rate. I can use the burn rate to verify my observations, but more importantly I could use it when testing with FO to know if wicking up or down is needed.

TallTayl Posted April 24, 2018 Share Posted April 24, 2018 Yup. Just did this with a new blend. I weigh at the end of every hour. This one is currently burning 5 grams per hour steadily, Calculating to nearly a 40 hour candle at present. 2 Quote Link to comment Share on other sites More sharing options...
Jcandleattic Posted April 24, 2018 Share Posted April 24, 2018 I weight my test candle also. This way you know how much wax is consumed in what time frames. That way when consumers ask how long your candles burn, you have an answer instead of just a guess... 2 Quote Link to comment Share on other sites More sharing options...

I guess I'm going to have to start selling some eventually. 1 2 Quote Link to comment Share on other sites More sharing options...

For testing I understand this, but for selling I would prefer a longer lasting candle, because that's what the consumer wants. 2 Quote Link to comment Share on other sites More sharing options...

I was like, "5 showers a day!" 😂 I really need to get more consistent with my testing, and record better data. I feel like I've gotten the basics down, and now it's time to get serious about product improvement. I like to work in baby steps! Thank you for the great questions and detailed answers about the testing process, this is exactly the next steps that I need to focus on! 1 Quote Link to comment Share on other sites More sharing options...
kandlekrazy Posted April 26, 2018 Share Posted April 26, 2018 Yes I do weigh as well. You'll find especially tins they will consume more from the 1/2 point down, just because the tin radiates heat. 1 Quote Link to comment Share on other sites More sharing options...
