Hi Wesley,
The short answer is that there is no easy conversion for this glaze to cone
6.
This is a calcium and magnesium based glaze and is probably has a wonderful
waxy buttery texture at cone 10. These 2 fluxes are what give the glaze
it's visual texture and feel and it is difficult to duplicate that at cone
6. I think I recall reading something by John Hesselberth of the difficulty
of making durable magnesium matt glazes at cone 6, maybe he will respond to
this if he has time.
Cheers,
John Post
I am hoping there is an easy way to convert this.
Can someone help or point me in the right direction?

No mix of these materials will melt well at cone 6.
I assume this is a silky matte glaze.
Perhaps the best way is to use a cone 6 silky matte that
is adjustable. Check here:

I think there is a silky matte base glaze at
www.gerstleyborate.com also.

Hi John,Wesley,
I think stable magnesium mattes at cone 6 can probably be done. I was
able to get stable glazes--but they were too likely to crawl to be
included in the book. I haven't given up. I intend to get back to that
for the next book. Now alumina mattes are another matter. I seriously
doubt any of those are stable at Cone 6 or Cone 10 -- certainly the
ones I have tested don't meet my standards.
Regards,
John
