Posted Image Does anyone have a good cone 6 gold glaze for reduction they'd share? I've evolved after years of firing to cone 10 to cone 6 gas, and have experimented to find some acceptable colors, but I'm still searching for a good gold. I had a gold-breaking-blue bright cone 10 glaze that I loved, and I miss it. Thanks in advance for your help.

I would love to see some pictures of the gold blue. I have a temmoku gold cone 6?
Thanks,

Yes, I'd like to try that gold temmoku, if you'd share that recipe. I'm writing this post from school and don't have an example of my beautiful gold/blue here, but will shoot one and send it when I get to the studio this p.m. I'll send you the recipe, if you like. I adapted a version of a glaze called "Nafzinger's Gold" from an old CM magazine.

John,
Here's the gold-blue cone 10 I love. Want the recipe? It took me asking one of my high school ceramics students to help me with uploading this picture, because I couldn't figure out how to do it myself. Laura.

Here is a list of ^6 reduction glazes from when I was teaching. We used ^6 reduction for 20 years in the shop 1980-2000. Not sure where some of them came from. The White liner glaze below with 3% rutile was a good gold.
Be careful when copying the recipes. The margins went haywire.
