Red Sea Glass in California - Info?

I found out about sea glass and decided to go searching. I found a lot on my first time out.

I found a red piece about the size of a penny. I was wondering were it came from.

I heard a story about a mission in California the fell into the ocean in the eighteen hundreds and it had red bottles in it.

I was wondering if there is any truth to that story and/or if there is any way to figure out were this piece came from by its color please help.
