Can anyone source dome disks in various size? This being opposed to flat disks. This would not be a plug frag rock either. The idea would be to glue a stem underneath or glue to rounded outcrops
Another member and I were going to make some and never got around to it. The thought was to make a mold to do several at a time and use concrete with coarse aragonite sand mixed in.
Rapid Set Cement All is a high quality, durable, easy-to-use, multi-purpose repair material that can be used for almost any type of concrete work, including concrete repair, grouting, anchoring, casting,
I suppose I am looking for a intermediate grow out disk and not a frag disk. You buy a frag. It starts (to in a lot of causes is) to leak over the edges of the plug. Flat disk are ok, but a upside down bowl would be better look.
I finally got around to designing some dome shaped frag plugs. The textured dome on the left does not have a stem. The one on the right has a stem that can be snapped off when you go to permanently mount the frag.
