Lead Metal Shot

Lead Metal Shot
chemical element: Pb
( shot - 2mm balls )
Lead shot is often used as a radiation shielding material that can be poured in-between small shielding walls and seams. Lead shot is easily melted and can be cast into what ever form is required. An 8 ounce jar contains about
2600 Lead balls, 2mm in diameter.
In pyrotechnics, this size Lead Shot is ideal for making round 'Stars', the burning pellets of
chemicals thrown out by firework devices.
Round Stars are made by rolling a quantity
of Lead shot in a large pan, then slowly adding
the Star composition, followed by spraying with
water (see our "Making Round Stars" procedure).

Lead Sheet
RadMax® Radiation Shielding
chemical element: Pb
( sheet )
RadMax® high performance, high purity & super dense Lead sheet - specifically manufactured for use as radiation shielding. Easily soldered and cuts with a scissors. Use for lining boxes for storing radioactive materials, etc.
See our Radiation Protection Page to purchase
Iron Filings

Iron Filings
chemical element: Fe
( powder )
Ultra high purity Iron Filings, approximately 40 mesh.
Although these can also be used to demonstrate magnetic fields when sprinkled on a sheet of stiff paper, their exceptionally high purity allows them to be used for a wide variety of chemical reactions and formulations where high purity Iron metal is required.
Hydrochloric Acid
Gallium Metal

Gallium Metal
chemical element: Ga
( chunks )
Small, ultra pure quantities of the element Gallium (atomic number 31), ideal for element collectors of those conducting experiments/producing alloys with pure Gallium metal. Gallium metal has an astonishingly low melting temperature of 85.6 °F, it will actually melt in your hand! It also expands by over 3% when solidifying, so it should not be stored in glass or metal containers as they will break when the metal solidifies. Gallium also corrodes most other metals by diffusing into their metal lattice. It is very important to keep Gallium away from any type of metal containers such as Steel or Aluminum.
Gallium readily alloys with most metals.
