After a long period of time, the silica-containing solution soaked into the pores and condensed into silica gel. The fusible components of the iron-bearing rock enter the silica gel, and finally the silica crystallizes into agate. It has a gelatinous texture, a hard texture and a variety of colors, usually green, red, yellow, brown, white, and other colors.

In the case of suspension, the support points must be solid, if the distance between the support points exceeds the maximum mentioned above, additional support and fixing need to be strengthened.
