The first one is a Rainbo my marble collecting friend--a very nice one.
The second one is a MCS or multi colored swirl--another nice one.
You can alway get more opinions from @Ric @Chad G. or @Fire1981 and I welcome them all as well as those from anyone willing to give an ID here.
Marble--On!!
I like it!
It may have been one of those that rolled down the cold air exchange and into the fire below.
Furnace folks used to find these quite frequently.
I does look like a Silver Oxblood from Akro--just bit by fire (coal or gas) a bit.
Marble--On!!
Agreed--Pretty cool with all of the lumps and folds involved.
My money is on this one being a Veiligglas marble.
@Mojo , @Ric and @Chad G. may have an opinion here as well.
I appreciate all opinions and hope to see some more.
Nice find!
Marble--On!!
These are older marbles and there may be a few "corks" involved as well.
Nice group--break them up and give multiple images of each for a better ID.
Just a few at a time.
Marble--On!!
Really nice!
Fires is a Pelt--yours may be a CAC -imho.
I appreciate all opinions and hope to see some more.
Nice marble regardless of the maker!
Marble--On!!
