Our ceramic coral frag plugs do not need to be cured before you are able to use them in your tank. 
 
Using reef safe glue just place your fresh frag to the plug, tile or disk and place it in your tank and watch it grow. 
 
At Stone Age Ceramics we fire all of our products in a kiln at 2000 degrees making them 100% inert and reef safe.
