rough side of large Zapata sagenite 2
This is the rough side of the large chunk of sagenite I found near Falcon Lake and Cox's Fishing camp, south of Zapata, Texas. You can see I still have not removed all the calcium carbonate that builds on the rocks as they sit near or on the shore line of the lake. Muriatic acid, added to water, will remove it in one day and will not harm the agate. You can also see the tiny details I observed and it is very difficult to tell there is any color inside.
