Answers: Actually, I have to recognize I am not exactly answering your question, but you brought posterior some memories of my childhood, My mum and dad had some Christmas tree lights that be sort of candle shaped and when the candle bit got hot over the bulb the grease inside bubbled like a lava oil lamp. This was contained by the late fifties/early sixties, but I still remember them.
