text: I am just at testing stage and very new to this candle making malarky but having some success with a few fragrances.
  Question is: when testing over and over and over again, do you re-use the candle vessel???
  I have the 20cl tins and I don't think testing in something different will be the best idea so need to test in the tins, but do I need to throw them away afterwards? Can I use them to test with the same fragrance again or will this impact the test results in any way???
  It just seems super wasteful to keep buying and throwing away tins each test!
  Thanks for any and all help - you have all been very helpful already 😁
