At Cosy Aromas, we put every single one of our fragrances through rigorous testing, and pride ourselves in ensuring that they are up to our high standards of being not only beautiful fragrances, but also highly scented. The temperature the wax is being warmed at whilst in use is also important. If it’s a somewhat cooler temperature then the scent throw will be quite subtle. If the temperature is higher during warming, then the fragrance will be stronger. The size of the space in which the wax melt is being warmed is also a contributing factor. For example: The smaller the room, naturally the fragrance will vaporise and fill the space quicker The larger the room, the more time it will take to fill the space.
