Powder resin is a compound which is a mixture of pigments, fillers and additives such as silica and polyvinyl alcohol. Its ingredients are very light; typically less than 1% by weight in the mixture. The powder resin cannot be made by conventional methods such as mixing solids because of the high viscosity of its molten precursor. This magnetic iron powder filings article will explain how to make enough powder to form a thin, homogeneous film.
Powder resin has been used since ancient times — it can be found as far back as 200 BC in an Assyrian building at Khorsabad, Iraq which was garrisoned with weapons using this material.

- As intellectual toys, children can improve their intelligence and creativity at the same time because of the coordination of hands and brains. Besides, it can also improve the communication and affection between you and your children.
- Be able to observe the mystery of magnetism at close range! Explore the basic concepts of magnetic field, including magnetic pole and attractive force. Using these scrap iron, a magnet (not included in this product) and a piece of paper, you can observe the force pattern generated by the magnetic field.
- Simple and affordable classroom or science fair experiment .Visualize the earth’s magnetic field.
- Inhalation, consumption and prolonged direct contact with eyes, skin and clothes must be avoided at all times. Wash your hands thoroughly after use.
- Includes a single jar (13 ounces) of Iron filings (particle size: 60-80 mesh).
- Jar features a convenient shaker lid that turns to adjust flow (like a spice jar).
- Usage tips: sprinkle a small amount of Iron filings onto a piece of paper (not included) and move a magnet (not included) underneath to illustrate the pole patterns of the magnetic force field.
- Storage: when you’re done exploring, fold the paper and use it to carefully pour the filings back into the jar for mess-free clean up and storage. It should be stored in a cool, dry area without heat and ignition sources.
