MgO "stabilizes" the burn just as well. it reduces the smoke very
slightly (no way you could detect it).
The main "problem's" are dimensional change and hard to ignite surface.
The tight grains can be solved by taking off a thin layer of paper. The
surface can be sanded down.
Both are "manufacturing" issues and should rightly be treated as

These have been stored a long time after opening the original packaging.
I would not dream of trying to turn them in a warranty claim.
I wonder what would happen if MgO were used in manufacturing instead of
pure Mg;would it eliminate swelling(at the cost of more difficult to
Would be curious to know why they would want to
add MgO; however adding Mg could have the effect
of adding small quantities of MgO as an impurity. That
material could then combine with the NH4ClO4 to
produce Mg (ClO4)2, which is so hygroscopic, it
is used as a desiccant.

WL seems to be more sensitive to humidity. They do fine until you open the
sealed pack. I've had a couple grains swell so much they would no longer fit
inthe liner tube. One from a 3-pack of E18s I gave to the local Fire Dept
inspectors who checked out my stuff to take back and burn in their burn pit.

The slugs are inside the liners,and they don't slide anymore,and the

The best oxidizer in the package is the apc. You coul probably store them
in dry nitrogen and eventually run into the same problem.
What about storing in a fridge or freezer? Lower temp should reduce
oxidation rates by a factor of two for every 10 degrees C the temp drops.
