Flint Rock? "melted" brown parts?

[kladdhunden]

I have collected Flint rocks and Amber alot and this one flint rock i found has a few parts that looks "melted?" to it.
I found it a year or so ago and tried to find out why it has the special look but i find nothing.
To be honest im not even sure anymore if it is a Flint Rock, i just think it looks weird but i really like it.
Found on a beach in sweden.

Can Flint be melted?
any ideas what it is if its not a flint rock?

Hmmm, looks like flint, but I'm not familiar with stones in Sweden. Maybe EU will have an answer.

Från vart mer exakt? Exempelvis skåne har ofta flinta. Ser ut som en kalcedon i alla fall.

(From where, more exactly? For example Skåne often has flint. Looks like chalcedony at least.)

Thats easy for you to say.

Great looking specimen. Looks "extraterrestrial", but I'm not a believer in ET's wasting their time here.

I wonder if it is slag glass or even obsidian? Im not sure what the water would do to either one of the types. Saltwater I would guess.

Obsidian isn't found in Sweden to my knowledge, due to the ice sheets that once covered the land.

I would have collected it. It looks like flint. I found a flint-like specimen that is in nodular form and it has a similar hole in it too. I think mine was possibly used as a ancient survival tool. I'll post a picture of it tonight for a comparison.

Here's that specimen I found in North Carolina, US. I believe this is a flint-like nodule; however, flint is suppose to be rare here. It has a hole (or a large pit). I don't know if this stone was struck there to produce a spark or not. I'm not sure really how it was formed but I'm suggesting that it may be an artifact or an ancient survival tool. I have found artifacts in that general area though.

Hallands kust, Halmstad med exakt. har hittat mycket flinta men aldrig något med det bruna inslaget.

(from Halland's coast,Halmstad to be more exact. Have found alot of flint just never with that brown inlay.)

Skulle nog gissa på att så är fallet då. Flinta kan komma i många olika färger. "glansen" är väldigt typisk för flinta och hjälper vid identifiering.
För att svara på din fråga om det går att smälta flinta, ja det gör det. Kring 900 grader skulle jag tro.
Är den smält hade den varit mer glas-aktig i glansen. Tror den bildats så.

(Would guess that's the case then. Flint can come in many different colours. "Lustre" is very typical for flint and helps with the identification.
To Answer your question if flint can be melted, yes it can. Around 900* C I'd imagine.
If it'd been melted it would be more glass-like lustre. I think it was formed this way.)

Probably a form of jasper or chalcedony. The melted look is not from melting but from the mineral having formed around a softer material that has eroded away. From the luster its high in silicates. Might be a good item to make a cab out of.
