Fail: Cooked Marbles

Name: Shannon

Original Inspiration:


What I Did: Thought this one would be easy. Followed directions as it said, when I put the marble in the ice water, it just fell apart

My Result:

pinterest fail cooked marbles

Next Time I Will:  Not sure, would all the glass marbles break apart?

    They are such large pieces, I would try gluing them. Nothing ventured, nothing gained….

    I guess the idea is to get the inside to shatter without the outside shattering. Not quite sure how to achieve that – except just to keep on trying. I haven’t read the directions – do you microwave the marbles? My guess is to get the inside hotter than the outside – then when you put in cold water the inside will shatter but not the outside. Maybe just try again???

    Well, i did it ant it came out really well… Maybe the oven was too hot for the icy water and made the marbles break.
    Mine i put on oven for like 5 minutes on medium temperature the threw in icy water.

    I did this tutorial as well before, and I did have one or two cracked, but that’s about it, and I used both those, and the kind of opaque flat bottom glass vase decorating ones. I didn’t use a ton of ice, but enough to turn the water icey and have ice floating on the top.
    From the What I did, it sounds like just 1 piece was used, and that may have made it too hot, try it with multiples and see. Some of it just may depend on the quality of the glass used in manufacturing.

    I made these as a child and had one of the marbles for something like 20 years kicking around in my jewelry box. I have noticed that the “quality” of marbles today–sucks. So I might seek out better quality ones. I DO want to try this with my grand daughter tho so I will be looking. And I suspect that using ONLY clear colored ones will work–the ones with “cats eyes” are made differently and might just shatter because they are already primed to do that with the inclusions.

    We did them in a frying pan on the stove top way back then—some did shatter so using more than you think you need is def the way to go.

    There is a fab concept called “Prince Rupert Drops” (find it on YouTube–amazing!!!) that explains WHY this works as to the inner tension vs the outer “skin:” of glass. IF you work with glass you know that it needs to COOL slowly–in fact they use kilns to direct this heat and cool properly so it does NOT shatter—and this is also one reason why complex colored glass is sometimes “cased” in clear glass to bind it.

    I would not ness use ice water–maybe really cold water or water that ice had melted in–but you can experiment with that. If you know someone who works with glass they might be able to help you on this. They are gorgeous tho when they work!

    My guess – Trial and error will persevere.

    Why – Different glasses are made with different components, introducing physical properties to glass making them more or less resistant to rapid temperature change. Without doing a lot of math and having access to information that a marble manufacturer would never care to make public, you are forced to guess. I am not knowledgeable on glass “skin” as Comet suggested, but I understand the concept.

    My explanation – The rate of contraction of glass on the outside is less than the rate of contraction of glass on the inside initially, causing superficial cracks – in an ideal trial. Therefore, due to the relatively large surface area of the glass, and leaving the marble in for too long, the cooling process could easily cool the glass throughout, and way too quickly to cause only superficial surface cracks, and instead causing the cracks to propagate throughout…breaking your marble.

    My suggestion – Leave the marbles in the water for less time. Perhaps use a plastic or wooden slotted spoon to dip them in and bring them back out quickly.

    And, as Comet suggested, if your marble lacked the “skin” that other marbles possessed, I can understand how a marble could crack all the way through and fall apart, even when cooled less rapidly.

    I did a bunch of these and about a third completely cracked apart. Some crackled a lot, but most didn’t. The ones that did were fantastic, however! Broken ones are scheduled for use in resin jewelry…
