raku should NOT look like this
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. |
It was not the raku most likely, but encasing the red.
If you want to encase red, try a clear core, encase with red, then encase with white. |
Is the raku 104 or 96? Honestly those look thermal to me though
|
It looks thermal, but reds, oranges, yellows don't necessarily encase well. Like Eileen said, make them with a clear core. They are much less likely to crack.

Thanks for the reply Eileen. Seems I remember now reading about using a clear base, but for some reason I thought perhaps I was special. Or when mixing different manufacturers of 104. Anyways, I will give your suggestion a try.
Kathy; I am using the 96 octane. Have read it should not be a problem as long as I do not exceed 10% and I am sure one roll in the raku would not come close to that threshold. No worries though. The beads were interesting but only by so much. I am thinking I can get the result I want with frit. Cheers |

I never have any luck encasing 96 with 104. But the cracks I get are not along the mandrel either, so maybe it is the red.
|
The red is 96 but clear is 104 correct? Halved is usually thermal, but I think it's incompatibility in this case.
|
Ravenesque: All the glass (red and clear are 104) and the raku is 96 powder. So, a marble base of red 104, encased with super clear 104, thin layer of 96 raku powder, then clear 104 again.

I know Kris Shiable uses 96 exclusively in her fit beads because she loves several layers of 96, and lots of frit. But generally speaking Dusty is correct. 5 or 10% works well as surface design but not every single color. Some 104 may be 105/106. Some 96 may be off as well. The viscosity has a lot to do with it, etc. Raku frit on unencased opaque red is gorgeous, try that and not the powder. Julie Nordine uses a lot of both colors in her palette. Though she may use 104 Raku, I think most of us prefer 96. |
I agree, lampworkers have been using 96 frits on 104 forever now, myself included.

If the red is a CIM color, make sure it's not an "opal", those don't like to be encased. |
