  I've been thinking about cement glandes, but havn't tried this yet not having as much time as I'd like. But if you do please let me know if it works.

  Take some plastic sandwich bags, used is ok and cheap is ok. mix up some ready mix and put it into the sandwich bag forcing it  more or less into one bottom corner. Twist the rest of the bag together tightly and tie it off with one of thoes twisty ties. Hang it on the cloths line to set up. The pointed corner of the plastic bag and the twisted end should form a nearly purfect glande. It doesn't really matter how wet or dry you make the mix because it should still form fairly well to the bag. Just don't use a pleated bottom bag which will not work.

Like I said I haven't tried it yet, but it should work, the corner makes one point and the twist makes the second oposite point.

Anyway, hope it helps.

Let us all know.

Cement glandes do work!
I bought the regular cement but sifted out the rocks, leaving the fine powder. I then mixed it soupy enough to pour out of a plastic cup. The plastic egg holes were cut out slighty bigger to take the cement.  You need to let the cement try for about 5 days in the mold before prying apart.  They will break apart if it does not dry out in the mold. Further drying is needed once out of the mold. Once you sling these glandes, and see how straight they fly, you will sling nothing else. My accuracy has improved 100%.

Warning
Don't use the mortar for tiles. I tried it last weekend and when I tried to remove them from the mold, they just fell apart.  I was slinging today and could not get over how well my accuracy has improved. These cement glandes are a dream!! I also take a file and smooth off any rough edges. Don't be afraid to get the mix soupy enough to pour out of a bendable cup. And you need to make the holes bigger on the molds. It works, just keep trying!

At school we have a kiln and some clay.  I had to pay to use it.  I would say that you can probably get clay at craft stores, in fact, I am sure you can (I get most of my strings etc from hobby/craft stores, and they mostly have clay there).  Anyways, I suggest that is where you look.
