After reading "Mastering Cone 6 Glazes" I wanted an easy reference to the example glazes.

Click here to purchase an  eBook  version of this reference by Ron Roy and John Hesselberth.  Glaze Photos

My Excel spreadsheet  MC6G.xls  includes these glazes along with:

a.)  a listing of ceramic material we stock at our studio;

b.)  the cost per pound of each material, linked to the glaze recipes for cost accounting;

c.)  an Orton Cone Chart with references to the various temperatures where various reactions occur.

If you want to use this as a template for your own use, unprotect each worksheet.  There is no password required to unprotect the spreadsheet.  Depending on your version of Excel, Unprotect Worksheet is listed under either the Tools or the Review menu.

Norm, 

i actually came here this am to start a discussion on MC6 specifically.  Thanx for starting this one . Question - is that your own pic ? 

cp - by the pond, where the geese finally landed, and i think we have an Ibyss (sp)  also.

The expert photo of the best you can achieve with Waterfall glaze is from the book cover.

Waterfall glaze more typically looks like this.  You need to apply it quite thickly to look like the book cover.  You need to apply less when you're using an iron-rich dark clay.

We now slow-cool our kiln far slower at 1/3 the speed recommended by Roy and Hesselberth, so Waterfall now looks like this.  Someday we'll have to make some more with 15% Ferro 5301 to see what it comes out like when it has enough flux and glass to be an ultra-slow-cool glaze. 

As you can see when cooled at 50 F per hour within the 1,800 F to 1,500 F range the glass level falls below the top layers of crystallization, which is typically not that attractive  - unless you like that sort of matte.
