dgsh009 Posted December 26, 2024 Posted December 26, 2024 Hello If we have fe3o4 , can use that as iron powder in pyro comp? or how to convert fe3o4 to fe powder?
Zumber Posted December 26, 2024 Posted December 26, 2024 If you are looking for iron powder for fountain you should look for cast iron borings. If you simply search 'Cast iron powder for fireworks ' you will get lots of sources and they have variety of mesh size available.

A ready source for cast iron powder, useful for fireworks, is automotive brake drum turnings. They work wonderfully for old fashioned fountain or gerbe devices, due to the beautiful branching sparks given off when ignited and propelled by black powder type mixes. Specific effects can be achieved by sifting various mesh sizes from the raw brake drum turnings. WSM Edit: The iron will hold up better (last longer) if treated with oil to prevent corrosion when mixed with in pyro compositions. Edited January 1 by WSM
Zumber Posted January 2 Posted January 2 We produce cast iron borings for fountain, for that we use scrap carpenter files which is cheap source for us. Then these files are transferred to ironsmith then he heats files till it become red hot and it he gives ellipse shape using anvil and hammer so that it can be crushed easily then this red hot ellipse is immersed in water. Then using anvil and hammer and proper personal safety tools it is crushed and sorted out till we get desired mesh size. The work is very hard and takes much times and efforts but it is only produced for festival and not for commercial fountain production. Image of carpenter file. And here is footage of fountain.

Zumber Posted January 2 Posted January 2 Have you ever tried Google? Indiamart? You may need to go outside home and look/search for it.

That's right but for height we need high weight borings if you see video of fountain you can see how high it goes in sky. This heights can not be achieved by turnings that's the reason why we specially produce it and it's only for festival. Commercially you may use turnings and it can be produced readily with lathe machine.

It is a raw material for make iron and steels, and there is a lot in nature and mines
Zumber Posted January 2 Posted January 2 Happy new year you too ..!! Indiamart is actually online platform and provides link between vendor and customer. If you search over there you may see their mail Id and they also provide their contact number and you may contact them directly. I haven't tried Fe3O4 in fountain.

I don't know which part of the world you hail from, but in the US any automotive shop that turns/treats brake drums or rotors has scrap turnings collected as a waste product (hazardous waste, due to minor amounts of asbestos from the brake pads usually present). I usually take an empty container (I find metal cans with lids useful) and ask if I can have some. They are often glad to give you all you want, since it's less for them to have to deal with. If they ask, I typically remark on their utility in gardening. It appears that the iron powder/granules sprinkled lightly on the ground around rose bushes and watered in aids in producing more beautiful blooms. This is due to the iron being chelated by soil organisms and taken up systemically by the roots. Pineapples also benefit from iron in the soil, I'm told. As for treating it, first sieve out rust chunks, dirt, cigarette butts or any other garbage in there, then either store it till needed or you can use one of the classic treatments from literature. Usually there's a bit of turning oil from the lathe used to turn the drums/rotors on the iron, and that's okay (it helps preserve the powder somewhat, but not perfectly). Some prefer to use wax and others like to use a drying oil such as Tung or Boiled Linseed oil. I find application of either easier if a light, petroleum based solvent is added to the preferred coating material, dissolving it first, then mixing it with the dry iron powder. Next remove the solvent through evaporation or heating without open flame (for obvious safety reasons), while constantly stirring to more evenly coat the iron, till it's dry enough to be free-flowing. Treated iron will last longer in finished goods. WSM

I watched a video on youtube that makes iron fountain with an ingredient that seem was iron chelate fertilizer( i am not exactly sure about that material).
FrankRizzo Posted January 3 Posted January 3 Dgsh- As I told you in PM, iron oxide will not make sparks because it's already "burned" chemically. Any auto service shop will have a lathe for turning brake rotors. The shreds and powder produced by the machine operation are usually a waste product they will be happy to be rid of, especially if you offer a few dollars or some wine/beer in exchange.
