The plain white T-shirts are dipped into a boron solution, then heated in an oven at more than 1000 deg C, which changes the cotton fibres into carbon fibres. The carbon fibres react with the boron solution and produce boron carbide - the same material used to make bulletproof plates in armoured vests.
The resulting material was stiffer than the original cotton tee, but still flexible enough to be worn as such.
Well-Being Australia chairman Mark Tronson, who has documented some major conflicts associated with Christian ministries and missions, claims that some Christian ministers might need this kind of T-Shirt.
There are numerous situations, which can be verified by searching any common search engine on the internet, where a gunman has shot and killed within church precincts. That in itself is both a tragedy and a travesty, but it does happen, and surprisingly quite often.
However, there are more subtle slings and arrows to be contended with during day-to-day business. M V Tronson got enough of a fright when confronted with church politics in 1999 to call for help. He could have used that Boron T-shirt! The background to this has been published numerous times.
In his situation, Anglican Bishop, the late Right Rev Dr Brian King, wrote to the financial supporters of Mark and Delma Tronson's ministry where he took to task the perpetrators. This was later supported by Donald Gwynne St.G., who wrote a strongly worded letter to the sports ministry's Patron the Rev Dr Gordon Moyes AC, then Superintendent of Wesley Mission.
M V Tronson looks back on that period and is more certain now, than he was then, that there was a deliberate and manufactured attempt to bring him down and that included actions that would seriously damage his health.
He continues to be astonished that the Laws of State allow any accusation to be made against anyone at any time without proof, evidence or certainty, often anonymously.
It happens over and over again. It has recently been illustrated again with former Australian swimming coach Alan Thompson's situation. Anonymous accusation. No proof, no evidence. Four months later, the man's cleared. What a horrific process!
Moreover he says, we live in a world where destructive behaviour is part and parcel of life, and many Christian ministers are not immune to this aspect of our society. Maybe, when Christian ministers who have come under such attacks, might wish they had one of those 'Boron T-Shirts'. M V Tronson certainly felt this. He was very frightened and retains that concern.
