Gray fuse and Red quick match (same stuff)

[displayfireworks1]

I am posting this picture to confirm what I suspected about the so called gray consumer fast fuse. It appears to be the same fuse that is in the red quick match. These appear to be perchlorate based fuse. we now know it was basically mini quick match. Instead of five strands it was just two. The downside of the gray fuse is that it is prone to side ignition. I still have a supply of the gray fuse, here is a picture showing the two side by side. Looks pretty much the same to me. In the near future I'll video the two burning. I am posting this for review by some of the new members.

This is very interesting. I have tested small amounts of grey fast fuse and it doesn't seem shock sensitive like the red qm.
