Found the root cause of my ash glaze issues

I did a simple melt test.

My ash is not melting at cone 6. Thus all my recent batches of ash glaze look like poop.

So my next step is to find some more ash. That actually melts at cone 6.

And then remix all my ash glazes.

Hi, I found your blog while looking for cone 6 glaze databases. Any further word on your database project?

Anyhow, I noticed your most recent post, and most ash won't usually melt at cone 6, especially if it is washed. Generally, I think ash needs to be in the cone 10 range before it melts. I have had good luck melting ash at cone 6 by combining the ash with Frit 3134 or Boraq (try a line blend, because results will vary with different ash sources, but offhand, I think it was about a 4 to 1 ratio of ash to frit).

Good luck!
