Originally Chillums Pipes were made of fired clay. But nowadays they are made of different materials like clay, stone and wood. Chillums were earlier regarded as spiritual items since they were originally used by Hindu priests in India. Chillums are faster than other smoking instruments.
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. While smoking a chillum you should use a cloth so that you do not end up burning your hands.
Smaller chillums are better than bigger ones because they help in keeping the smoke hot and give you a mellower smoke.
