I find that the basic raku glaze of 80% gerstley borate / 20% nepheline
syenite with up to 15% zircopax (or alternatively 5% tin oxide) is off
white on Armadillo Clay's Balcones. This clay is a light peach-tan when
bisqued. Is there anything to try to get a more pure white glaze on this
clay or do I need to use a white clay body? If so, how much sand or grog
should I add to their Dillo White or porcelain to get a throwable clay that
will withstand raku?
Also, as a newbie, I've learned a lot from this group but haven't given
anything back up to now. Here's a start. I've collected about 100 raku
glaze recipes from various sources and stored them in GlazeChem, a
shareware program. If you would like a copy of the GlazeChem data file
(about 75kb), send me email. The file is designed to be used by GlazeChem,
but can be read using a text editor as well.

I use Dillo White just as it comes from the bag for raku and it works
beautifully.

I don't know about Dillo White or porcelain, but I use a basic
02-04 white clay from L&R Specialties in Nixa, Missouri and mix 10% fine
white sand or fire brick grog. I make sure I get a good 04 bisque too.
Hope this helps!
Peace & Prayers,
