Atomized Stainless Steel

Fine atomized stainless steel, chemically stable and non-toxic, good for adding weight, strength, or metallic finish to resins and epoxies. Particle size is about 44m, or 325 mesh, on average. Primarily 316, but because the original metal was recycled, purity is not guaranteed.

Atomized Steel

Atomized steel powder, much finer than "iron filings" sold in most "science" kits to "children" these days, excellent for magnetics, fireworks, or adding cheap easy weight to your project.

Very capable pigment for making magnetic pastes, putties, and paints, but a little too clunky for proper ferrofluid. Some paint mediums react with metallic powders over time, so we recommend mixing and using as needed.

Also works well for cold-casting, which is a way to cast objects with a metallic look, weight, and feel, but without the machinery necessary to actually cast steel. Simple mix roughly 1/1 by weight of this powder with your resin of choice, let cure, then polish for a metallic finish. As this is iron, not stainless (which we also offer), it will rust, just like actual iron.

Bismuth Shot, 99%

Bismuth is probably most well-known for the incredible crystals it forms, commonly sold at "mineral" shows, even though they are completely synthetic.

Other uses include low-melting point alloys such as solders and pepto-bismol. Bismuth is also the most diamagnetic element, meaning it repels all magnets, regardless of pole. However, the effect is extremely weak.

Polypropylene Resin

Industrially pure, natural, un-pigmented polypropylene pellets, used as a stock for the manufacture of plastic parts (121 billion pounds made in 2013), as well as an economical filling for beanbags and craft projects that will never rot or mildew. Pellets measure 3-5mm, and are irregularly shaped, as shown in the first photo.

Some facts about polypropylene:

Melting point: 170c (340f)
Density: 0.9g/cc
Chemical Formula: (C3H6)n

Potassium Nitrate, KNO3

Classic oxidizer for all projects, used in countless pyrotechnic and other reactions involving nitrates or oxidizers. This form is prilled, or in small 1-3mm round pellets, as shown. Also used as an oxidizing flux for precious metal smelting.

Obviously pyrotechnics are dangerous, so please don't try to make your own.

Silica Gel Desiccant, Blue Indicating

The classic silica gel found in those packets in food to absorb moisture and protect whatever doesn't like being moist, but with a twist: This silica gel has a small percentage of cobalt chloride, which makes it a beautiful blue when dry, and a pale pink when saturated, so you can tell when to refresh it!

Cobalt chloride is mildly toxic, so it is not recommended that you discard large quantities of this silica gel after use. Instead, bake it at 110C (or 220F) until it returns to blue, and it's ready to be re-used!

Also not recommended for direct contact with food, but perfectly safe to share a sealed container with it.
