Mikie and the students are making Aragocrete™ sculptures to sell in their town. They can make the very fancy rocks that are so hard to ship.
7/25/10 If you take pictures of your children making rocks, we would love to see them. The best image this summer will win $100.00 worth of fine GARF reef janitors.
This shows the Aragoready™ mix when it is ready. It is dry enough to not slump off of the spatula for several seconds. It is mixed with Caribsea crushed coral. We used about five parts crushed coral to two parts Aragaready™ mix.
1. One bag of CaribSea™ fine grade aragonite sand for Aragocretetm mix
2. One bag Riverside white cement
3. One bag of CaribSea™ finest grade aragonite sand for sand box.
4. Several long Styrofoam fish boxes
We begin this project by filling the first Styrofoam fish box with 2 inches of damp aragonite sand. The rest of the araganite sand is divided between several one gallon buckets. We make the Aragocretetm mix by combining 4 parts sand and 1 part white cement by volume. Add just enough water to make a thick paste. DO NOT add too much water and try to then add more sand and cement. It is better to add the water slowly. You will need to make the Aragocretetm mix thin enough to flow from the mortar bag and thick enough to hold it's shape while you add the next layer of sand.
This is the tool that we use to form the legs. You can get many other tools to form other size legs
We are making the legs by pushing the tool into the base until it touches the bottom of the box. We add more Aragoready™ mix to the hole until it is full. When it is full we push the tool into the leg to leave it hollow.
It is important to make the legs as far apart as possible, so the table will be stable. The three legs make the most stable platform.
We have added the extra Aragoready™ mix to the leg. We add dry gravel to keep the hollow open until the mix dries.
These covered plugs can be reused many times to make holes in your rocks. It is time to remove the plugs when the rocks are almost hard . This keeps the plugs from sticking in the rocks.
You can add enough extra mix to allow the leg to be open on one side like a small cave. I try to make the opening on the outside of the table so you can see the cave from the front of the table. This weeks table will not have open legs.
By poking a finger into base between the plugs we can form a large hole in the center of the base.
The center hole is filled with dry gravel to keep it open. We overfill the hole to make a space under the bridge we will put over the center hole.
We use extra Aragoready™ mix over the mound of gravel to form the bridge. The more gravel you pile up the larger the opening will be. Be sure to blend the two parts together where they touch.We use extra Aragoready™ mix over the mound of gravel to form the bridge. The more gravel you pile up the larger the opening will be.

This table is ready for curing, and it will be finished in 10 days. The Aragoready mix cures in 1/3 the time of cement. You can see the hole under the bridge, it looks like the handle of a basket. You can make the legs thinner than this if you do not have to ship the finished table.
Well now you can make your own table with easy legs :) Each one will turn out unique, and that is why I have so much trouble waiting to dig them up. Please help save reef by making your own rock.
