Oxide question

[mwar15]

This is 1:1 stain with nepheline Syenite.

Both mixed with water and sprayed through an airbrush. I like the yellow but the grey is a little too shiny. I think less coats would be better. the grey is almost a dark green

Here is the same mason stain one with nepheline Syenite and one with greatly borate.

 

[Hack Yeah!]

Wow, I would never guess that was the same stain

BTW, I like both!

This is a 14x11x4 that is straight RIO sprayed. I love the color and fake patina look. It’s tough to beat

When you spray this on, do you do anything to mixture to keep better suspension with water? Do you add Bentonite? I will sometime use strait oxides but have to shake up the mixture often, and would like to get more consistent water to oxide suspension. Thanks-- Rob

Seems we attracting as many new potters as we are bonsai people.

I do not use anything I just shake it real good before I put in the sprayer and keep shaking it

Thanks, that's what I have done-- I have tried a little defloculent, but it really does not work in that volume. Thanks so much for the reply-- beautiful work!

Your use of stains is very interesting and completely different than the usual use of stains that involves gradients of hue and color. I like the pebbled look but I wonder how well they endure. You are using stains and oxides as a surface treatment whereas my use of stains and oxides typically involves getting the stains deeply into the pores or the clay body and wiping the surface.
This is no criticism, I like your work but your finished product is more like a mat glaze. I would be curious to see one of these pots after a few years of weathering.

It is hard to say. I only have one pot that has a tree in it And it’s only been outside for a year and it really hasn’t changed much. I’m hoping to get a few more trees in some of my pots this spring and I’ll get back to you in a few years.

That carving of the clay is such a cool feature. Can you share how it's actually done?

I’ll try and take a video or photos the next one I do

This Mason stain is real crapshoot. I thought it was gonna be darker than this, but I also only did three or four coats. It’s 8” square

Got 4 new stains. 3 browns and a grey.

Did you do the same thing with those stains, mix with Neph Sy? Perhaps adding to a matt base glaze would be interesting.

I like using Gherstly Borate when you can find it. Otherwise a frit like 3143. I use a very small amount to act only as a bonding agent with a nice mat finish.

I used GB but it’s still shiny. I am going to try NS and see how it works or try and just spray it straight.

You shouldn't be getting a shiny finish if you use just a little GB or frit. I have not used NS for this purpose. Someone else mentioned possible use of a clear mat glaze.

I think I might be using too much GB. I was using 2:1 stain to GB
