Abstract
A vaporization device includes a wick with improved aerosol production properties relative to a traditional wick, for example one formed of silica fiberglass cord. According to some aspects, the wick is formed of discontinuous fibers that are not packed together and that have varying orientations, creating a plurality of voids, or spaces, between the various fibers and along the length of the wick. This design of voids along the length of the wick allows for rapid wick saturation and air exchange. Because of this, a user can take successive long puffs without noticing much difference in vapor production, as the liquid quickly (e.g., within seconds) replenishes in the wick.
