Dating petrified wood
Argon is typically used in furnaces because it is inert gas.
Therefore the materials inside the furnace are deprived of oxygen and can not burn.
Sounds like a simple experiment easy thing to do and if any one can report on that being done and the results we would like to know. Progress at the Isotrace Radiocarbon Facility, Radiocarbon 28, (1992) p.   This material gets covered by silt and other material.
In fact it adds credence to the belief that in nature it can happen quite quickly. Accompanying the Battelle article is an electron microscope photo with an electron microscopic image showing a cross section of wood that was artifically petrified in days.Another thing that is so significant here is their claim that the carbon in the wood remains. supposedly " mimicking a natural process that takes millions of years.All the carbon has not been replaced by silicon or titanium. Since it supposedly took millions of years to form, the carbon 14 test should show a nil carbon 14 content. " Notice the unsubstantiated dogma that petrification takes millions of years. There is no absolute proof of that in the literature You will find that the scientific literature will say that such and such fossil was found in the so and so formation which is 100 million years old.This new type of ceramic could be made from natural biological material, which is cheap and renewable and easy to form.As explained in their article the process involved soaking wood in acid infused with either titanium or silicon and baked in an argon filled furnace. The original cellulose structure of the wood acts as a template.
