i was thinking about makeing some clay glandes i think that will be easer then makeing lead glandes but i was wandering
what kind of clay you would use? can you use clay that you dig up from the ground if you firer it ( i did that win i was a kid 
to make marbles)?

Well, clay from the ground can be great stuff.  Can take a while, though.  You have to dry it out, get out the impurities.... but it tends to be worth it.  My Uncle makes pots, and he uses a bunch of methods.  He sometimes uses clay from his garden.

I used to just let clay glandes dry out good.  No firing.  They held together fine in the sling, and a couple of good rainstorms return them to dirt, which is very ecological.   

I bought moist gray clay at local craft store.  25lbs for about $15, and I think I got about 350 glandes out of the 25lbs, each about 75grams dry weight.

Sizing, then forming them into little footballs by hand was a lot of work, but they sure did fly well!
