As the silica water fills up the cells of the logs it crystallizes into mineral quarts or opal (Trees to Stone, p.2).

Making the logs plane more beautiful, put dear rich mineral deposits seeped into the logs during the fossilisation process and a rainbow of act upon became a permanent masterpiece for us to see.
