Well Chris, I'm hooked. Going to have to make me some marbles!
Actually I've been wanting to make some 'spheres' to incorporate into some other projects, but I have made one sphere and several eggs before and know how long it takes. Six cuts to make the square, 8 more cuts to take the corners off, a little trimming and you're ready to get started!
It doesn't make that much difference but we probably ought to start a “Marbles” thread under “Lapidary Creations” for future collection pictures, so feel free to start one if you want to post more pictures.
I went to the Marble Connection forum and browsed for a while but did not see ANY stone marbles, all glass. It seems to me that the marble gamer using real stone marbles would have a distinct advantage over the glass marbles. In fact, I would think the stone ones could inflict serious damage to some of the glass ones. Are there any rules about when real stone marbles can be used, or is it just the hardest marble takes all?
Yes, I've looked at your Rolley Hole Link and we can talk for quite a while about the different rocks you are using to make your beautiful marbles. But first you will have to develop an appreciation for the hundreds of different formations and 'grades' of Quartz there are out there. For instance, Agate is one of those different formations of quartz. You have low-grade 'ugly' quartz and then it gradually gets clearer and better and better in quality and then it gradually starts to look like Agate. It can be a very fine line between quartz and agate and folks love to argue about it. And once the stone is rounded and polished it can be impossible to say for sure without knowing where the rock came from or look at a piece of the rough. So yes, in the future, if you have any questions about what the rock is, you definitely want to take pictures of the rough before working it. A big piece of it that you aren't going to work would be additional help with identification. Jasper, Flint, Chert, and Agate are all different formations of Quartz. And there's lots of formations of Quartz and Quartzite.
I haven't even gotten to any questions about your stone marbles but I just want you to understand it is a very fine line between the rock materials you are using and you have to look real close sometimes and/or be able to see it rough.
Here's one question to get the marble rolling; Is the dark beauty in Pic 1, the same as the one in Pic 10, and is it top row far left in Pic 2?
You've made some real beauties, but I don't see anything close to what I would call Tenn Paint Rock Agate. There are sites on the internet with maps that will pretty much show you the range of the Paint Rock. And here's a link to an old thread on here for a small sample of the Paint Rock;
https://rockhoundlounge.com/cgi-bin/yabb252/YaBB.pl?num=1378067217That brown mottled rock in Pic 6 looks like rock I've seen interbedded with some of the chert out there in Tenn and Kentucky. I know what you mean, it's somehow 'softer' and fun and easier to work, but in the back of your mind you're wondering how long it will last before falling apart. It is like an indurated argillite, or a rock hard porcelain soupy clay. Not sure what to call it? Sedimentary?
Oh well, enough for now. Thanks for the link and pictures!
Lots to go over on my part for sure. I do highly recommend getting into making marbles, but it can be an addiction and obsession for many. I'll have to start a thread in the lapidary creations section at some point, though for a while I'm out of making marbles while I build my own setup.
If you search the forum using the search tool you should come across some Rolley Hole threads, or using Google they should come up. On that forum the primary thing there is indeed glass marbles and glass marble collecting (which I know nothing about). It's easy for my threads to get buried with all the talk of glass there. On that forum I'm more of an oddball than anything since most people on there don't play marbles and are more there for nostalgia and collecting I think. The folks on there are very supporting though so it helps keeps it going, With glass vs stone, we only use stone for Rolley Hole and glass marbles are reserved for other games. Glass is too hard and brittle for play and some players will purposfully break glass marbles (as target marbles) to show they can do it.
I do have some uncut and partially cut pieces I can post, but I'm wondering how hard it would be for the folks on here to really see these pieces well. When I take a photo, a lot of detail sure gets lost. Many pieces have intricate patterns almost like lace doilies the old folks used to have on furniture.
On the varieties of quartz and grades of quality, I never have thought of it this way and that actually helps a whole lot. I started just calling it all "some form of quartz" when park visitors ask me about particular materials. I do like thinking of different grades of materials which helps me understand some of the more odd marbles I have laying around here.
To answer your question about the marble in pic 1, it is not the brown marble in pic 10. It is however the marble in pic 2. It is a grey material that was in a very grey nodule. That was a small piece I found in a stream around here and was told from the start it wouldn't be a good marble as the players don't like anything grey. No one here plays with a grey marble because they are supposedly too brittle and hard.
The marble in pic 6 is the one that got me wondering about what material it is and the one I was thinking was some sort of paint rock Agate. The original piece was very layred and it was mostly layers of quartz with some brown sandy layers in-between I had to work around.
Thinking now to my cubes I have now, I don't have much more for the grey stuff but did start finding material a laser really lights up (but it makes a greyish marble). I was told that if a laser really lights it up, it's a higher quality material and the laser will light it up regardless of color. That is how the very brown marbles and butterscotch marble are.
On the brown/butterscotch, those marbles all came from the same piece and I still have some that I haven't shaped yet. What was odd is one end made a couple white marbles, then as I got further in, it darkened.
Anyways I'll have to make a master thread of all this to keep up. Currently I'm occupied with so many projects plus moving that I do get sidetracked with it all. Kinda a chaotic period but no matter what, my mind always goes back to marbles.
