I haven't tried marbles,but have tried broken up colored glass the problem that I had with it was in not being able to judge a correct amount. Sometimes I'd get a nice even coating,but in most cases it would puddle in a blob. The shape probably contributed to the puddling. I don't think that you have any problem with the glass melting through, W.

We fire marbles all the time and find you need a high fire to get them to
melt and flow well. Firing to ^10 on stoneware bisque to 05 or so has worked
very well for us. We have had lots of fun with this but do not expect the
glass to stay the same color after firing!

An alternative I have used is colored window glass
commonly called "stained glass". I got some left over
scraps from a shop that makes windows and suncatchers
and put it into a plastic zip lock and then into a
thick scrap athletic sock and then gently crunched it
with a hammer, very little force. The first time I
thought the glass would shred the ziplock bag, but
surprisingly, very little puncture. This "powdered"
glass I layered into the bottom of 05 bisque and it
flowed well at 05-06 glaze firing. It did craze as I
expected as it was not well matched for expans/contr.
I was cautioned that some colored glass as well
as glass marbles sometimes had hazardous
chemicals for colors that one should avoid vapors.

Should be fine as long as all the glass is
contained within the clay.
