Seamus told me that if you want that volcanic look and maybe it has to be thick walled enough, add salt rock to the mixture. The salt will over time melt out leaving holes. Never tried it but souds super cool.

The next time that I make one, I do want to add the fibers that make the cement super strong, not that I've had a problem with strengh. I want my cement tikis to last two hundred years.
