Petrification is a process where the original material of the wood, bone
etcetra, is replaced molecule by molecule by a different material. The
transport medium is water. The usual subsitute (if I remember my geology
correctly) is silica (the stuff glass is made of). So it shouldn't change
the PH. It may affect hardness, and silica may be more of a problem in SW
