Do you have favorite glazes that you use often; and what are they?| July 10,2012 Potters Council Question of The Week
Posted 10 July 2012 - 01:56 PM
I am curious to know about your glazes. If you make your own glazes, can you tell me where you found the recipes?
School, friend, book, other? How did you choose your favorites? By color/surface?
I saw John Glick in a workshop recently and he said he uses more than forty glazes. Wow! Here at the University studio we have about 20 high temperature glazes,
and about the same number of low temp glazes, but no one person uses more than a few favorites! That was the impetus for my questions--

1. a matt glaze worked back to ^6 from ^10. It is a smooth matt texture excellent for functional work. It takes colorants well. I used it in ^6 reduction for decades and I am using it in ^6 oxidation too.
2. I was mixing a faux celadon about 10-12 years ago and made a mistake. I realized the mistake but had 10,000 grams of this glaze. It turned out to be a blue gray semi matt translucent glaze. It is a favorite for spraying over resist carved slip decoration. I added a jpg to my gallery with this glaze.

I make all my own from scratch.
The ones I like best-
A green satin Matt at cone 11-satin matts feel buttery smooth and are not shiny like gloss glazes also not dry like a true matt glaze-satins are harder to get and when they are working well they look super. Cobalt carb and green copper carb for colorants-the right talc is key for the satin matt look-satin matts are very fussy and the wrong talc will shine the matt right out. I will use serria light for this one when my-Older not produced talcs are gone they are running low like desert talk or C30 talc
I'm on my last bags of each and only use them for seafoam green The HT100 talk works but had asbestos in it and was taken off market
Mine is called seafoam green and its a modified school glaze from 35 years ago-
Another is a black that is super with a large firing range cone 8-12-Its gun metal when cool and shiny black when hot
I like it by itself with white or red on it or as an underglaze or overglaze on just about any glaze. I use it the most as an underglaze.
Its a simple simple 3 ingredient glaze, cobalt Oxide ,nepheline syenite and alberta slip (I used to use albany slip)
I got this from a friend long time ago-I call it Zacks black-its pricy to make and we use it in 15 gallon batches-lip dip and brushing
Its a solid dinnerware glaze. You will not find a better black I feel as most blacks come from over saturation of colorants which can cause problems
Heres the recipe
My other well used is a saturated iron glaze called red/black which can go red-brown or almost black-it usually is redish brown
Its a high Iron glaze I mixed and added mels orange (high iron and high rutile)to by mistake. I like it so much I always make it that way now.
Late night and that enough for now.I have used these glazed for 35 years and know them well now.

Shino, tenmoku, kaki, oribe, chun, dark runny ash, light runny granite/ash, spodumene matt.
Added 2 new ones a year ago...... a dark heavily crazed celadon and a Hagi-like one. Still wondering if they'll stay.
One of my standbys is basically Hamada Shoji's nuka glaze adapted to more western available materials (except for the rice husk ash):
33.3% black rice husk ash
33.3% washed mixed hardwood wood ash
29.0% Custer feldspar
4.3% 325 mesh Flint
(Seived at 40 mesh)

Second one is a Gun Metal Satin Matte I have used for 20 years. It contains Manganese Dioxide, so it's only for decorative surfaces. At its thickest, it is a beautiful dark grey, almost black. Brushed over a white slip or engobe it shows up as a midnight blue. Both of those are great on textured surfaces.
The third is a Satin/glossy refrigerator white which is very forgiving, and heals over wonderfully, and takes color beautifully, whether mason stains or oxices. My favorite rendition is a rutile/copper light aqua with granular ilmenite. Works well over Cushing's Lt Green
