Abstract:

Ignition of casting powder exposed to the sun in yelaluminum-foil- lined Leverpaks occurs when the casting powder is heated to its auto ignition temperature through the focusing of the suns rays by the foil-lined walls. The minimum height of exposed wall of a yellow Leverpak nec essary to focus the suns rays on the powder and produce ignition is 6 inches. Exposure to the sun of casting powder in blue paper-lined Leverpaks does not focus the sun of the pow der. Single-base casting powder is less sensitive to ignition in this manner than double-base or modified double-base casting powder however, single-base powders are still sensitive.
