Both of those are soft woods that if you made a pipe out of would only last 1 session and like Bud Green says you would be smoking them the entire time. Literally smoking the pipe. Don't kids do the soda can pipe anymore?
Yeah it's an actual ceramic pipe made to look like the can pipes from our youth. That is not my can pipe in the picture, it was just the best looking one that showed up for can pipe
Theoretically that's possible, though bowl weight would most certainly prove impractical. Think of heat-shaving spiders without burning the house down using a butane torch: hairs on spider legs only require some relatively small amount of energy to catch fire and glow, then its abdomen eventually explodes... Better extinguish that flame before paint or varnish suffer!
The recommended materials for pipes are glass, titanium or decent quality brass. I personally prefer glass, though it can still be hard to come by in some places. Online head shops may be an option?
