i was melting some salt and some of it turned flurescent red?

i was melting some salt using a pencil butane torch to test how hotsalt needs to be to melt in practical, and i noticed something odd as i was melting it, and that thing was that there were some flurenscent red dots appearing on the molten salt, what were these? was it metal sodium? or sodium oxide?

Likely it was impurities in the salt. They could be either organic or inoganic. If its iodized salt, probably iodine.
