Spontaneous Combustion


Occasionally life hands you mystery.
Yesterday I began the process of restoring and maintaining my outdoor furniture. First, I wiped it all down with a dry rag. Then, I lightly sanded each piece with a sanding sponge (this was the part of the process that my daughter ‘helped’ with, getting very upset when she found me re-sanding the areas she 'already did'). After the sanding was complete, I washed the set with a mild solution of warm water and Murphy’s Oil Soap mixed in a large metal bowl. When I finished with the washing process, I poured out my bowl of soapy solution, temporarily stored the damp rag and sanding sponges inside the metal bowl and left them sitting on the front stoop while I proceeded to treat my furniture with tung oil.

 A couple of the pieces I am working on
 
This afternoon, I headed out to give the wood a second coat of tung oil and noticed I had left my mixing bowl on the stoop overnight. Not wanting to leave the sanding sponges out long term, I picked up the bowl with the intention of returning its contents to their proper locations…and discovered the mystery.


My first thought when I caught sight of the contents of the bowl was that the rag in the bowl had been the one I used for the tung oil and that the oil had somehow disintegrated the rag. Upon further inspection however, it became apparent that the reaction that had taken place in the mixing bowl was one of combustion rather than disintegration and memory served to remind me that the rag never came in contact with the tung oil. Somehow, a metal mixing bowl with a soapy rag and two dark colored sanding sponges ignited a blaze sufficient to turn a good portion of the rag to ash, char a couple of nickel sized holes in the sanding sponges and blacken the side of the mixing bowl.
 
Mysterious. I am fascinated by the perfect storm of circumstance that must have been required for my inadvertent science experiment, grateful that the blaze remained contained within the mixing bowl, and quite sure that I couldn’t repeat that particular little accident even if I tried.
