You should try clay chillum, nothing like it!
I had three... I had a Charlie, Bianca, Kanjo, my three favorite chillum makers. The Charlie was my favorite, plain terracotta color with a simple pattern on the outside, but the smoothest and best chamber. It cleans in seconds when warm, and cleans PERFECTLY. Kanjo makes very feminine designs, but on HUGE chillums. We are talking 2 to 3 cigarette mixes. The Kanjo and Bianca were gifted to friends I made here, travelers I will never forget. The Charlie ended up bleeding out the side eventually, years of faithful service took their toll. I still have him somewhere I will go dig in the boxes.
I don't like the Indian clay chillums. They are OK for a few weeks I guess, but I have not found one with a proper inside and a good stone.
We don't see many Italian travelers here any more. None that bring chillums anyhow. South Africa used to be an easy place for these things, sigh...
But my little one-man chillum there is tooled from a piece of solid Quartz crystal
VERY unigue. It has rainbows and water inclusions, if you are into that kinda thing it is a very powerful stone to start with. It is far from perfect on the inside, smooth enough but not quite like a good Italian chillum. I made the stone myself though so even amateurs can pack my chillum and it will smoke easy.
I am getting pretty nostalgic here. Making me think of times that will never happen again, the late 90's early 2000's in South Africa were AMAZING. I spent the millenium festival in my home city surrounded by thousands of people that did not share my first language. It stayed a part on the hippie trail for a few years, now it is more Tanzania and Malawi. I miss it though.
