How do I get a better hot throw or cold throw in candles with fragrance oils?

Achieving good scent throw in candles comes down to three main factors: choosing a fragrance oil that is compatible with your specific wax type, using an appropriate fragrance load (within safe limits for the oil and wax), and giving your candles adequate cure time before testing. Some makers find that small additions of certain carrier oils to the wax can improve diffusion, though this requires testing to find the right balance. If the throw is still disappointing after adjusting load and cure time, the fragrance-to-wax pairing itself may be worth revisiting.
