If you hold it up to the light and look through it, is it Green?
If so, you have dichroic glass that transmits green and reflects Pink. It looks pink against a dark background. These colors will shift as they are heated. Gently fused, the colors will shift to Teal/Light Pink, but if overheated it could shift to undesirable results.
You need to protect the coating side from the flame. If your glass has been fused, then it will be more than obvious which side has the coating, but it will still need protection. Visit here to see how to determine which is the coated side and which is the glass side.
Note: We sell dichroic glass, but it is not compatible with Effetre or any other COE 104 glass. Our glass absolutely will not work with your glass.

Once you determine which is the dichroic side, put that side against the bead. Gently heat the glass side and start applying the dichroic glass to the bead. Tuck in the edges of the dichroic glass as you go to seal the dichroic layer in. Work as cold as possible.
If you want to apply a small chip of the dichroic glass, heat your bead until just tacky, apply the chip, dichroic side down, then seal the edges of the chip with glass to seal in the dichroic coating, go slowly and work as cold as you can.
Show us some photos when you get done.
