My surprise when I opened the kiln. All my raku on red had not just cracked, they had presented themselves on the half-shell, so to speak.
Any insight on what I did wrong would be great. I made them by
-make a round with red
-encasing red
-rolling in raku
-oxidising flame
-quick cool with marver
-encase once more
My black beads do not split and look fine, but I only encase once. Why twice for the red? To avoid the darkness the raku brings to the bead. Can't see it when I use black as my base but ruins the red when I place the raku without encasing first. Obviously it is the double casing, but why? I am using COE104 effete glass and clear.
