Balcony Shoot #12 - Quickmatch Test

Date: 2003-10-10

Description

Quick test of some quickmatch I made up, eventually for set pieces and more immediately for the ignition system of a small girandola I am working on developing.

Match pipe is 7.5 mm ID, dry spiral-rolled from light duty kraft, then painted with syrupy gum arabic solution. Makes a very nice glossy pipe when dry.

The blackmatch is slightly exotic. The meal was mixed with 10% moist paper pulp and worked into a thick paste with syrupy gum arabic solution. No dextrin was used, the gum and the paper fibres being the only binders. The coating was sized with a die at 2 mm OD, and the string allowed to sit for 5 minutes, then shook in a jar with some Zinc wheel driver composition (I wanted to get rid of it) until a thick touch-dry coating formed. Finally it was sized again with a die to 4 mm OD then allowed to air dry for two days.

Good Stuff!

This blackmatch is amongst some of the best I have ever made. The gum and fibres makes a somewhat flexible match that doesn't crumble when bent. Much better than dextrin binding alone.

The quickmatch worked as required, the thin match pipe transmitting light and showing the burn progression. It was a little slow, but was clearly accelerating, the length was only 2 feet, which suggests at burn rate of more than 10-20 feet per second
