1/2″ fiber board prepared just for you with divot (now a hole) and fiber hardener on all 6 sides

Great for Soft glass marbles. (and Boro too!!)

Not sure how large a marble this will secure, but I have made marbles over 1.75 inches with out an issue.

Care instructions:

This Hardened fiber board with a HOLE will last years if properly used.
Do not break the hardened seal on the outside of the board.
If the seal gets broken, use a fiber hardener in the exposed area and fire the piece to approximately 1350 ℉ for an 30 minutes.

If the hardened outer “crust” gets broken, use a fiber hardener or rigidizer in the exposed area let dry completly and then fire the piece to approximately 1350 ℉ for 30 minutes.

Cautions:

1. The marble may roll out if tipped at too steep of an angle. Please use caution, your marble is hot!
2. If you put the Fiber Board into the kiln, use caution on taking the board out of the kiln, for it will be hot. (I use kevlar gloves). No not use tweezers or pliers to lift the marble fiberboard out. This will break the fiber “crust”
