Hi, especially to Marcia in Montana,

I can't find the cone 6 reduction recipes in the archives anywhere, and =
have tried several combinations of headings and subjects. Can you guide =
me as to what they are under?=20

I have a wood fueled kiln and wondered if you have experiemented with =
them in that type of atmosphere. I often have a cold spot in the bottom =
back corner and down low, and thought he top can get to Cone 12, the =
bottom is more like Cone 8...so lower fluxing glazes would be most =
useful for this area!

Thanks for your help.......

Joan

Hi Joan,
I happen to have archived the cone 6 chit chat recipes (posted in 1996!), and I pulled the reduction recipes from that thread out to repost for you, I have not tested these myself.

Dear Joan,
I tested Marcia's cone 6 redux. recipes in oxidation. Many good results.
There is also one called Hal's Apple Green that I fire in ox. and use fairly
regularly.

They are listed in the archives and if you search authors name as
aliskin@mail.dk
they will be among the recipes listed.

Otherwise, let me know if you still do not find them and I will send them or
direct you better to them.

regards from Alisa in Denmark
