I would like to induce more pin holing in my shino tea bowls. I have read
that too much tin oxide in a glaze will create pin holing "fault." Any ideas
or experience with using Tin Oxide to create a more dramatic orange peel
effect?

Hello Jeff,
I have observed that I get pinholes more often when I use
OM-4 ball clay than any other ball clay or kaolin.
I thot maybe this could help.

Hi Jeff ,
I'm late because I was teaching a glaze calc course last week.
Tin does raise the viscosity second only to Zirconium and Alumina in the
list - it also raises surface tension.
So my answer would be - if you use enough.
Alumina would be the material of choice though - shinos like alumina.
You may also want to try some material which disassociates later on during
a firing - like strontium carb - I would try a small amount in a test to
see if that would work.

Thanks a bunch Ron. Very helpful. I'll try some new tests pretty quick as I
hope to have another firing in about a week. I'll keep you posted on any
interesting findings. Thanks again.
