Here we share the recipe of this 15 sample triaxial blend in the course:
B. is a mixture of 1/4 parts of K126 & 3/4 parts of G&S 254 (preferbly dry weight)
C. as a base we used pure porcelain with addition of 4% blue/grey stain (Cock keramiek)
Here is the picture and link for the Triaxial blend designed by Derek Au. And the link were you can find this chart and when you look further you will also find line blends, biaxial blends and much mor. A super website for all things glazes and ceramic materials and thinngs like this :)
mix 50/50 porcelain and 254, pure porcelain, 1/4 nero black clay 3/4 porcelain
the second row are mixes of K126 red clay and porcelain or 254
 A line blend of 5 were we used
- pure porcelain+2% of cp 34 turqouise (left)
- pure porcelain+6% cp51 indish yellow (right)
and we have created 3 steps in between... they match so well together!
Just a reminder you will scrollllllllllll a lot also for lesson 3 and more details, tips, etc. :)
Here are the samples of the combination pure porcelain (left) and the nero black clay (right)
These samples where made on to dry samples - as you can see in this picture, the first sample is pure porcelain and with the third coat the shrinkage was to big on the G&S 254 stoneware clay, same on the second sample that looks like very dar clay but it really is 3/4 pure porcelain and 1/4 nero black clay so the shrinkage is still about 15 % Just try it and when pure porcelain is to difficult on yout designs and work - try different things and combinations :)
So you want to get to know the ceramic stain you have bought, here is a good exersize for that:
Weigh out your base in 10, 20 or 30 gram batches - i always start with 10 grams...
And take your pigment/stain and weigh out 1,5%, 3%, (5%), 8% and 12% on thise 10 gram samples.... picture below is this exersize without the 5%, sorry bit lazy because i already now this stain very well... so the first is 1,5% - 3% - 8% and the last 12% a good thing to learn were the saturation point is. as you can see a tiny bit of difference between 8% and 12% - but when you are making 1kg it can spare you like €8,00 in stain costs :)
As we spoke about in the online lesson 3 - there are some flaws in these samples, pinholes (speldenprikjes) as shown in the picture you see them. When you look at the samples with white glaze they only apear when we apply only one coat, when we aply a second coat they disapear, how, why....sometimes stays a mistery but by making these samples you learn sooooooooo much :)

Look at it and know!!Yes when time is precious this helps - when you make your blends let them be soft leatherhard and stamp them on the front, on the back you can describe information that is also important, like the base you used, sometimes the parts (3/4,or more) or %. Don't forget you also can do this after the second fire with a sharpy (permanent marker with a sharp point) - give your blend a name/code and then right that on the back for easy reference...
The experimental tiles:
always make some tiles for your self, it is fun and sometimes even a lovely present for a loved one, you can also make holes in the upper corners and you have a bathroom tile :)
Here we were talking about layers og clayslib/engobes (lesson 3) and this is one of the examples, a thin (one coat) of our sandcolored slib, a paper resist technic in the shape of an oval and some branch decoration of a darker clay slib....
Finished with our glossy glaze A0.....play, experiment and please share you findings at:
