Thank you for the info! I had a slight mental setback yesterday 😅 when I came to think about the magnitude of marble collecting and that most of my marbles may be "nothing" and that some may be "something". Does it make sense? Still, I love my marbles as most of them have been in the family since my mother was a child.
Mojomarblelicious is very helpful as he is sending me pictures of what to look for. Lately he has been aiming me towards clear glass marbles with single coloured fat veins. 😊 By the way, what do you call the type of marble that you'll see in the top right of the picture I posted? What I think is the general word for them here in Sweden would translate to "porcelain marbles", even though porcelain is not the material. 😊
