Was found in Bleckley County, does it look cooked and/or worked?

I'm just trying to identify for someone else. It was found on a clay road in Bleckley County. Some say it was cooked chert, others not so sure. One person said some type of gneiss. It doesn't look exactly like chert to me. I wondered it if was rhyolite. I read where it can appear purple. I've see purple clay pretty often.

In a child's hand so it looks pretty small.

It`s heat treated Coastal Plains chert. That particular piece cooked out nice.

It’s a beautiful color. Little people finding artifacts … I love it

Yeah that's heat treated unless somebody carried some Alibates chert all the way here from the Texas Panhandle. That's the only stone I've seen naturally that color.
