Hi All;
I started playing around with some crackle glaze. I did some high feldspar
glaze test and a high alkaline glaze and would like to see if I can make
some new patterns - if that's possible. In Glaze Cone 6 by Mike Bailey, it
appears the higher the expansion, the bigger the crackles. Another chapter
[10] mention high silica. However, the pattern are one dimensional. I would
like to get some 3 dimensional crackle glaze, like if it cracks in layers
and perhaps in different shapes; like the snowflake crackle.
Do I mess about with just the COE? I also wonder if I change my firing ramp
to a slower climb near top temperature, it would make any difference. [Just
thinking out loud. I'm trying it anyways]
If you have seen any reference in any books that can lead me to more
information for investigation. I would appreciate it.
Thanks

Hi May,
If I understand your question correctly regarding "3 dimensional=20
> crackle glaze", take a look at Brian Gartside's web site at:
