Explosive Limit of Armstrong’s Mixture
K. L. and B. J. Kosanke When investigating the cause of an accident, it was necessary to learn something about the lower explosive limit with regard to phosphorus content in Armstrong’s Mixture. A short literature search did not produce the needed information; thus a brief laboratory study was undertaken. Because the results of the study …

Further information about HDPE Mortars
Someone recently raised the question as to whether there could be potential problems with high density polyethylene (HDPE) mortars from contact with detergents and from exposure to sunlight. This article was drafted in response to a request to address those concerns and also to present an update on the status of acceptance of HDPE mortars …

Reduction of Shell Ignition Failures
A shell ignition failure means there will be a live dud in the fallout area after a display. If that dud is not retrieved, is found by a member of the public, and that person is subsequently injured as the result of mishandling the dud shell, an insurance claim against the shooter and manufacturer will …

CMC – Its Properties and Uses
CMC, as it is commonly called, is more properly referred to as Sodium Carboxymethylcellulose (carboxy-methyl-cellulose). In the food industry it is also frequently referred to as cellulose gum. Ref: Selected Pyrotechnic Publication of K.L. and B.J Kosanke, Part 1, (1981-1989), pp 106-106 (K1_106)
Japanese Shell Break Radii
(Derived from data provided by Dr. T. Shimizu, private communication) The National Fire Protection Association, Technical Committee on Pyrotechnics is in the process of revising NFPA-1123, Code for the Outdoor Display of Fireworks (formerly called Public Display of Fireworks). In preparation for considering the appropriate separation distances between spectators and mortar placements and between spectators …

Destructive Testing & Field Experience with HDPE Mortars
In an earlier article on High Density Polyethylene (HDPE) mortars, results from an initial series of tests were published (Pyrotechnics Guild Int’l. Bulletin, No. 54, p 5). Those results will not be repeated here. This article continues by presenting the results from an additional test, a summary of the author’s field experience since the first …
