What a boring name for a title, or so it may seem.
Chemistry was required to hear the shot heard around the world in the Battle of Concord on April 19th, 1775 leading to the American Revolutionary War.
Today, I will demonstrate a technique I use for such chemistry, the manufacturing of black powder. Like many good things out there, many chemical manufacturing processes are lengthy and it is my intention to make several posts about them. As it is a national holiday for those that engage in dulling thier senses with substances, I find writing about the manufacture of USEFUL products fitting. You are welcome to argue with me in the comments below.
Yesterday, I was gifted a Harbor Freight Rock Tumbler ITEM 67631 for my birthday and I was really excited.
I will use it to prepare airfloat charcoal for an upcoming science project I have planned.
The tumbler is relatively simple to operate. Fill the drum with the product and the media necessary to either polish or pulverize.
I use several different media for mechanically pulverizing raw materials. The ones I primarily use are lead shot, steel bbs, and glass marbles. Lead is the heaviest and the most practical but is unhealthy to handle without gloves and ventilation.
The charcoal will come from the World Renowned Campfire!
The pieces need to be smaller so I use a cutting board and a wood or rubber mallet to break them up.
After the peices are managable,
I put them in the barrel or container and weight the heavy media and the soft charcoal. It is important to be aware of the weight as you do not want to burn your motor out or break a pully belt.
Using the machine is easy. Flip the on switch and away it spins. I like to check on mine every couple of hours and sift the smaller particles by unscrewing the lid and pouring the contents into a strainer.
I add additional charcoal and repeat. This is the product I have so far.
This is not airfloat, but it is pretty small. Additional time would be necessary to make smaller particles.
Well, that is all today for my nifty Birthday present! I look forward to continuing these little projects in the future!
