Fragrance is everything in the candle industry. At Welburn Candles, our expertise as specialist scented candle manufacturers has been built over decades of fragrance formulation, blending the art of perfumery with the science of candle chemistry.

How Scented Candle Manufacturers Optimise Cold and Hot Throw

Cold Throw

Cold throw is the fragrance emitted by an unlit candle — what your customer experiences when they pick up the candle in a shop. Driven by the fragrance’s volatile top notes.

Hot Throw

Hot throw is the fragrance released when the candle is burning — the scent that fills a room and drives repurchase. Achieving both excellent cold throw and exceptional hot throw is one of the most demanding challenges in scented candle manufacturing.
