A chillum is a narrow funnel used for smoking. It has a filter stone inside it which prevents the substance from falling into your throat. Though chillums were originally made of fired clay, nowadays they are made of different materials – including glass. While smoking a glass chillum you should use a cloth, so that you do not end up burning your hands.

Glass chillums are quite attractive and are available in various shapes and styles. A glass chillum is preferred by many smokers because it doesn’t sweat, impart any impurities or give any flavour to the smoke. Besides, they can also be cleaned easily.
