Cone 6: Shipwreck is an aquamarine gloss glaze that contains an iron crystal. As the crystal melts, a small iron speck appears. The glaze appears mysterious like underwater footage.
Cone 10: Colour darkens.
TIP: SW-212 Peacock is the base glaze. For a lighter crystal effect, you may try applying two coats of SW-212 Peacock with a third coat of SW-54 Shipwreck.
