I work for a ceramic tile store. My question is can I use a plain 4x4 ceramic tile to use as frag plugs?
Ive seen them used before. The only concern I see would be any glaze or paint used in it.
Is their any type of prep work I have do to them before using them.?
As long as they're new and clean i usually just throw them in a sump for a week or so.
Should you do that with regular frag plugs as well or can you use them fresh out of the bag?
Honestly you could use them out of the package. I like to throw them in the sump for a week or so just to get any "new plug" dust off of them.
