Glaze course by Tine Secher day 2

So the second day of the course finally arrived and I was very excited to see the results of the last course’s many tests.

We worked with everything from stains (blue) to Tinoxide, Magnesium, Siliciumcarbid, Rutil to strotiumcarbonate (don’t know the english words for them), but they are all very determining for the outcome of the glaze process.

The tests were done with a mix of lets say 16% tinoxide and 5% stain or similar.

Below is the full test from all nine participants. (Sorry its in danish).

I learnes so much on these course days and the day was over before we knew it.

I can highly recommend taking a course to learn the key elements of glazing and to learn how to test properly and structured.

I really had to engage my very hidden and far to seldom used math skils, if you could even call them skills – I would probably call them basic survival skils, as I am hopeless in that area. So I stick to the basics and the safer selections as I am mostly fan of the glazed that are either pastel colored mat or shiny and I really like the transparent glaze as well.

The standard recipe for a good alround glaze that fires at 1240 degrees celcius:

Nepheline syenite 40%, Kaolin E 10%, Whites/kridt 20%, Quartz/kvarts 30%

To that you can add stains (max 7%) and oxids and flux/flus

Looking at the picture you can then determine what will happen.

So the top row is either Blue stain on the left side, or a mix og blue stain and titanium in the middle and titanium only on the right side. The middle one is ½ of each and then 1/3 or 3/1 on each side of the middle.

I hope that makes sense.

It did for me and I am now ready for testing glazes next week at Thoras workshop in Frederiksværk. Yay

Have a great day ahead
