Rice Hulls or alike
Posted 25 November 2008 - 08:21 PM
What about ground up corncob?
perfect substitute for if not better then rice hulls.
In my experience rice hulls have a tendency to compress to much when loaded into a shell, which in some cases can cause a fire block.
Especially when the shell is broken very hard with a whistle or flash booster, resulting in poor star ignition and break.
NOTE: rice hulls available here are NOT the same as the Chinese use in their shells.
Corncob has a number of advantages:
1: Absorbs little water
2: easy to coat
4: readily available
5: composed of hard grains that don't compress(very important).
Available in pet shops, it is used as bedding material for Guinea pigs etc.
Rule of thumb: the heavier the carrier the lower the ratio.
Rice hulls typically have a ratio of 6:1 Bp/rice hulls,
Because corncob is more then twice the weight for a given volume then rice hulls a lower ratio of 3:1 or 2:1 is used.

hey what do you think about hay straws if we cut them in desiered size and coat them?
I'm sure they would work, but I think cutting would be an unecessary hassle as other much easier options are available.

Seems like it would. I see that barley has a 15% water content, at least that weight could be gotten rid of by oven-drying.
But that's with everything still inside, won't that add unneccessary weight to your shell?
