First time BP problem

15 July 2010 - 02:54 PM

Hi guys,
After years of wanting to get into pyro I've finally pulled my finger out and ordered the various bits I need to have a go at making my own BP as a first step.

I ordered all my chems from hobbychemicals.co.uk

For the first go I thought I'd make a very small amount, keeping it simple I measured out 7.5Gm of Potassium Nitrate, 1.5Gm Airfloat Willow Charcoal and 1Gm Sulphur. The chemicals are already very fine and not wanting to invest in a mill just yet I thought I'd give them a quick grind in a wooden pestle and mortar.

In hot anticipation I marched outside with my concoction formed a small little pile (not contained) and lit at arms length.
Then nothing.
Kept the flame close for a long time and had several reattempts still nothing.

Even if it were poorly mixed or not 100% accurate I was expecting a little whoosh or at least for it to combust!!

Very disappointed I was really hoping to get off to a better start.

What on earth am I doing wrong please?

Thanks muchly
