During pouring and burning, the Zinc core wick provides increased wick support since it is the most rigid of all cored wick. This wick type features a filament of zinc running up the wick’s center. Zinc core wick is known for its cool flame profile and its ability to remain upright in the molten wax pool. This wick is typically recommended for use in paraffin wax tealights, votive, pillar, and container candles.
