Homegrown Oxidizers Part One
Not all of us live in an area friendly to fireworks. Access to these articles of celebration, let alone the materials to produce them may be extremely limited if not completely banned. Reliable information to produce fireworks raw materials is very difficult to find and even consulting professional chemists us...

Homegrown Oxidizers Part Two
The Anode
A key to modern chlorate production is the MMO anode. These were hard to come by many years ago, but now are so common that surplus material can be had at reasonable cost through careful searching.
Part of the success of these MMO anodes is due to their large surface area (on a micros...

Homegrown Oxidizers Part Four
A fellow enthusiast has offered this method:
When is a batch finished?
For maximum anode life, one should end a batch run when the potassium chloride concentration drops to about 10% by weight. Without expensive analytical equipment the easiest way to infer the concentration is by measurin...

Journey of a Rookie Shell Builder > Making 30 3" Paper Ball Shells in 3 Weeks

Posted jwitt on 02 August 2010 - 05:38 PM

I'm writing this blog entry because I'd like to share my techniques and findings. I think it will be a nice introductory tutorial to those who are considering making paper ball shells.

Starting my second big shell building project got me thinking about efficiency. I wanted to get these shells built in the minimum time possible, while still being as...

You'll put your eye out... > Lead Dioxide - PLATED!

Posted Swede on 16 January 2009 - 11:30 AM

It has been a long road, but I now have two anodes plated... one of them looking fairly sad, while the other looks excellent.  The weather has NOT cooperated, and in addition to the physical discomfort (cold!), there are process issues as well.  Jugs of distilled water are ice cold, and the hot bath (60 to 70 degrees C) must really struggle to maintain...

Houston, we have perchlorate.   B)

I've been finding this blog, for me, has become a source for easily accessible notes.  For example, a while back I made an entry where I did a bit of math to determine expected yields, and investigated costs and efficiencies... THAT particular entry, I have referred to a few times for data and information.  This is...

Pyro Musings for Thought > Large MDF Formers

Posted marks265 on 04 February 2017 - 10:06 PM

Large Case Formers!
Do you really want one? Well, if you do and don't have a big lathe maybe these ideas can help you. I had a smaller cheapy lathe that I bought from a big box store. They don't sell them anymore and I burned mine up trying to make a former that is larger than an 8 inch'er. I contemplated what to do about this and I came up with a...

PyroRob's Blog > Small Fire Crackers that give a Big Bang

Posted PyroRob on 09 January 2017 - 06:23 PM

     I am always trying to find a safe inexpensive ways to improve  my fireworks. Last 4 th. of July I came up with nice replacement for fire cracker tubes which can also be used as reports in a mortar shell. I had ran out of tubes and forgot to order more in time for the 4th.  I decided to run to Menards to get some hdpe pipe to...

Pyro Musings for Thought > 6" Mill Jars

Posted marks265 on 17 December 2016 - 07:29 PM

I've had or made about 4 different versions of ball mills in my day. When things got serious and I moved up to a large ball mill the one thing that never changed was the mill jar that I use. This style has been an "old faithful" for me so I'll share what I have done. The material I use is schedule 40 PVC plumbing pipe and parts. There is a lighter duty PV...

spitfire's Blog > Tailing bombettes and other items

Posted spitfire on 22 September 2014 - 01:52 PM

What is a bombette in the first place? Simply a tube shot from a small mortar, like we see in commercial cakes linked together to shoot 12, 19, 30 shots one after one. Each shot tube contains a slightly smaller tube containing a clay plug holding the delay fuse, stars and flash burst. When they are fired we see a colored rising tail. Red, green, gold, gli...

Posted mkn on 04 March 2014 - 10:30 PM

Hi all,
Here is a 3 lb rocket with Ti tail, the 4 " cylinder has 3/4 " glitter comets and timed reports( the timing was not  great) I also put a bottom shot on that must have had a seal problem, because it burst during the shell burst( you can see it in slow motion view, and hear it in the video as almost a double burst.)
overall , home made t...

You'll put your eye out... > The Bucket Cell - pH Meters and Probes

Posted Swede on 03 October 2012 - 05:08 PM

Very cool - a "Post to Blog" function.  I thought I'd give it a try, since this post has some hopefully good information in it.

pH Probes and Meters for the (per)chlorate process

I spent far too much time on pH probes today.  Again, the idea behind the simple bucket cell is so one doesn't have to mess with pH probes and meters, but I...
