Volcano Filling ChamberThis Volcano Filling Chamber is used for vaporising your ground up herbs, and are the same as the ones that come with the Volcano Vaporiser. They are available separately now, as it is always useful to have spares in case of loss or damages. Vaporisers themselves offer the safest way to smoke any herbs, and the Volcano Vaporizer is recognised as one of the very best on the market.
