One works fine, the other looks like the wax is just a white mass laying in the bottom of the globe. Ive read a few of the other discussions, now, I'm really lost, I thought the bulb provided the heat, what is a coil?
Maybe someone would be nice enough to go A-Z and explain how this all works, I think this lamp was made in the 80' or 90's but just a plain conical globe with blue water.the Lava (wax?) is white, just laying on the bottom. If you're so inclined, an email would be nice... firstname.lastname@example.org
