-
- A good flash composition does not need a sturdy case. Teflon would just
- be an unneeded addition.
-
- It is still being argued whether flash mixtures actually detonate - at
- least, in smaller quantities. Maybe someone else will have some cites
- on research which has been done recently to settle this question. Dr.

- initiated by a strong enough blasting cap. He also indicated that large
- quantities will detonate, when ignited.
