That was pretty interesting to, it was also interesting to know that there are some different types or colors of flint some far better in quality and color to look for then other types. I like learning more about any type of stone to me that’s part of the fun in this hobby for me anyway. Thank you |

Not all flint is Polish flint. Every piece of Polish flint that I have seen has the patterns in it. I'm from Poland so I can tell something about these flints. We have a lot of flints but most often are black or brown (chocolate flint). Some flints from glacial deposits have really cool colour like red, orange, yellow or even blue, but it's only a few milimeters coating link, link, link (this one looks almost like an agate). We also have interesting flints called "świeciechowski", it's brown and have some bright spots (calcite intrusion) link. Finally we also have big deposit of stripped flint. Brighter strips are actually parts with more micro holes. Nobody yet knows why it forms like that. You can find it in glacial deposits, somewhere around normal flints or in near Ostrowiec Świętokrzyski where it creates deposits with only stripped flint. Biggest flints can weight almost tonne, but usually it weights about 5-15 kg (10-30 lbs). Actually most of it deposits is in forests where you can't dig, on fields where nobody will let you dig, or in private limestone mine where also you can't dig... but there you can find stripped flint on small dumbs (most of it is small pieces, but some of it can be satisfying.. Biggest piece I have weights 26 lbs. In Poland it costs about 3-10 USD per lb of course rocks. Sorry for bad English, I'm not very good in languages. Thanks for the information on Polish flints. Have you ever tried heat treating the brown (chocolate) flint to see if it changes color?
BTW, welcome to the forum and your English is just fine!  |

I agree with hummingbirdstones, your use of english is just fine, far better than most people who use it for their first (and sometimes only) language.
Thank you for the information and pictures!

BTW, welcome to the forum and your English is just fine! No thanks, I haven't experience in heating rocks and I don't like changing colours of rocks, but I found someone's results of heating flints in different temperatures: link, link. |
