I tried the #8 blue from here.(local studio owner made it )
I got crawling and it is beautiful. See pics
I' d like to do 2 things with this
1. Repeat it/ and with different colors
2. Fix it so it looks like sample.
When delving into glaze formulas etc... I get that same headache I used to get in chemistry class...
I've Re read the article many times including further research into cte, clay and glaze fit, along with Lot of new glaze vocabulary.
the piece In picture is mostly standard 266, mixed with studio recovery clay, with added fine ,medium and coarse grit. Unknown cte.
As far as I know the (I didn't mix it) the recipe is true to formula.
Issues and questions:
Why did it crawl vs. craze? How do fix?
Mag carbonate off in recipe?
Does firing schedule greatly affect this? Eg ramp hold cool times.
Is there a big difference between cone 6 and cone 7 in how this glaze looks?
Does standard 266 or Laguna 900/ WAC-628, cte compare high water earthen red or brownstone?
How much Epsom salt to prevent deflocculation?
Picture 2 shows a drip. It is approx. 1/4 inch from clay surface. It is dangerously close to dripping off. Since current formula crawls (less tension) and not craze can I get away with thinner glaze on bottom?
Since crawl has less tension, can I get away with glazing small test plates one side?
(I understand testing is king, but would like some input)
Try #4 formula. With unadulterated clay.
Test with both bowl like form , and one sided test plates.
Use current recipe with unadulterated clay. See if results change.
Thanks in advance for and advice answers or comments.
