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).

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.

Charcoal (ACTIVATED)

Charcoal (ACTIVATED)
( Activated Carbon )

chemical formula: C
( coarse granular )
A unique material that vigorously absorbs chemical impurities. Activated Charcoal is a form of Carbon that has an exceptionally high surface area. It is claimed that a single gram of this material has an effective surface area of well over 2,000 square meters. The micropores in Activated Charcoal provide superb conditions for adsorption to occur; the adsorbing material can interact with many surfaces simultaneously. Another important use is to treat poisonings and overdoses by oral ingestion. It prevents absorption of the poison by the stomach. By far, the most common use is in Filters to purify liquids, compressed air and gas purification to remove oil vapor, odor, etc.

Ultra pure quantities of the element Cesium (sometimes spelled Caesium) atomic number 55. ideal for element collectors of those conducting experiments/producing alloys with pure Cesium metal. Cesium is one of the most reactive metals known to man - it will ignite upon exposure to air or water. For protection, our Cesium samples are sealed in glass ampoules under Argon gas.
As its melting temperature is only 83ºF, it will become liquid on warm days.
Pure Cesium metal has been used as a propellant in ion spacecraft engines and in vacuum tubes.
Ampoules contain 1 gram of pure Cesium metal.
Note: Ampoule style/shape/size may vary depending on current availability, but will always contain 1 gram of the element.

( small chunks )

Calcium Carbide is generally used to produce Acetylene gas. When it comes in contact with water, it will react violently, producing bubbles of highly flammable Acetylene gas and steam.
Old miner's lamps used Calcium Carbide and a slow water drip to generate Acetylene gas, which was ignited to produce light. Carbide Cannons were old toys that used Calcium Carbide (which they sometimes call "Bangsite") and a little water to make their loud reports. A fun material to experiment with.

( powder )

Caffeine is an alkaloid that's found in numerous plant species where it acts as a natural pesticide that paralyzes and kills certain insects. In Humans, Caffeine is a central nervous system and metabolic stimulant in small milligram quantities, however, ingestion of only slightly larger amounts can be fatal. This material is for experimental purposes only and not to be added to food or drink products.
Caution: Caffeine is toxic. Use normal safety precautions (wear a filter mask/respirator and gloves) when working with Caffeine. Accidental inhalation of fine particles can be dangerous.

Calcium Metal


Calcium Metal
chemical element: Ca
( small chips )

Ultra-high purity Calcium Metal chips.
Calcium is a chemical element; atomic number 20.
Calcium metal reacts with water evolving Hydrogen gas and producing an alkaline Calcium Hydroxide solution. When ignited in air, Calcium metal burns with a bright white light, forming Calcium Nitride.
In vacuum systems, small amounts of Calcium metal serves as a 'getter' for residual gasses. Calcium forms a thin white oxide layer on its surface that protects the metal from additional oxidation.

Cab-O-Sil


Cab-O-Sil
chemical formula: SiO2
( fluffy powder )
An anti-cake agent that makes powders stop clumping & flow evenly. In pyrotechnics, it is used in
Flash Powder mixtures to increase the burn rate (typically 1 gram to every 100 grams of Flash Powder). This makes the Flash Powder "fluffy" allowing for much faster flame propagation.
