Debbie,


Tung oil has high levels of a conjugated triene, α-eleostearic acid (9-cis,11-trans,13-trans-octadecatrienoic acid).  Linseed (flaxseed) oil, has high levels of a methylene interrupted triene, α-linolenic acid (9-cis,12-cis,15-cis-octadecatrienoic acid).  The tung tree originates in southern China.  Flax seed is believed to have originated in the Republic of Georgia.  Distant cousins at best!


Kind Regards,

Brian Mueller, CHO

There's your fuel and the fire-starter, PLAIN OLD TUNG OIL.  All these "natural" plant-derived setting oils will do this.

 

 

 

Is this a cousin of linseed oil, well-known self-combustible?

Birkett's hypothesis: "Any chemical reaction

that proceeds smoothly under normal conditions,

can proceed violently in the presence of an idiot."
