It's possible you're thinking of sulfur in a different context. Here are a few possibilities:
* Matchmaking in the past: Historically, sulfur was used in fire matches. It was a key ingredient in the early forms of match heads, which ignited when struck against a rough surface. However, this is not related to matchmaking in the modern sense.
* Sulfur in a different context: Sulfur is a naturally occurring element with many uses, including in fertilizers, medications, and industrial processes. It's not commonly used in matchmaking.
