I am using Standard low fire slip and Duncan dipping clear glaze. Till that time I fired ;
bisque cone 04 glaze cone 05
bisque cone 04 glaze cone 06
bisque cone 05 glaze cone 05
And all the results : my pieces are yellow even though my bisque is white before glaze firing. I have to make them clear,transparent and dipping glaze. And I really want them to be whiter. I have no choice to use brush or white glaze cause I make decorations on my cups that they should be seen and I have to be produce a lot and use dipping to be quicker.
I use bamometer and my glaze is 35 bome.
You can understand from the pictures that I have another problem with the bottoms of my cups that are like overburn and come more yellow.
I am posting pictures.
What am I doing wrong?
