Looking To Start Mixing My Own Glazes

Recommended Posts

I have never used floating blue before, but it looks like it needs a thicker coat.

 

After looking at it closer again I beleive you are right. Thinking back I dipped it twice thinking it was thin. The SP was 1.4

You may also find that for the clear glaze, you want it thinner than the others. I find somewhere in the 1.3 range is what I've been having good luck with (over a dark clay where bubbles are super obvious).

 

Callie, does it look to thick from the tile?

 

I was experimenting with some colors that I applied on greenware and later when I applied the clear over the colors and fired many of them washed out. I applied some of the same colors to bisque ware and poured a commercial glaze (not clear) over the pot then sponged off most of the glaze and it came out nice. I'm not sure if it was because the colors were applied to greenware as opposed to bisque. I can post an image later if you are curious..

ron, commercial glazes have an ingredient that allows the underglaze colors to remain true.  it took years, and Min's help for me to get the one i use over green.  it always came out grey before.

 

joseph, the larger test piece is a beautiful design.  have you made it even bigger?  are you selling anything yet?  i would like to get something like that before you become famous and unaffordable.  or, maybe you are already unaffordable.

Any idea which ingredient that is?

it is a proprietary ingredient so we will never know.

Or quite possibly not using a certain ingredient.

 

Thanks anyway

If they had any magical ingredients their marketing team would be all over it. They have the same rocks/periodic table we do with clever people behind them.

you are right, there is an article in this week's CAD blog that appears at the top of this page.  the writer describes making underglazes and tells exactly how she did it.  it is the ball milling for 12 hours that makes the difference.

 

tom coleman told a workshop audience about having glazes made with an ingredient that was a preservative and emulsifier that was very expensive.  he sells glazes like elaine uses and whatever it is allows the glaze sit on a shelf for a long time without separating into various layers.

 

but, maybe i am wrong about that, too.  after all, i am just some old lady.

You are much more than that. You are a wonderful person and valuable member of this community who is so very generous with her experience, knowledge and thoughts. Don’t think we all have to be in agreement about all things, that’s part of what makes these forums work, bouncing ideas etc off each other to help fill in the blanks.

Nutmeg - I'm planning on placing a wood knob on this one.

If these are your beginner glazes, cannot wait for graduation. I noticed the nutmeg has higher sheen.

Thanks, but they are all published glazes so I can't take credit for them.

 

The top of the nutmeg has a high sheen to a very dry looking bottom. I was actually going for that on the eggshell and I was trying to make the nutmeg look more even like the eggshell.  Oh wait, I did that on purpose.

the forms are very nice, i think you got the idea of close fitting lids quite well.  the handles are distinctive and make me wonder how you did them with such sharp edges.  

 

oh,  yes, the glazes look great.

That is indeed a big compliment coming from you, thank you.

 

I used a small extruder that I made for the handles.

How did you apply your glazes? I am just curious. Looks like you sprayed them. Either way the results are great. Are you going to work with these three for a while? Also nice to see your scaling up the size of your test.

I sprayed them with a Critter, I'm a lot happier with the results over brushing. My wife wants to dip glaze so I may mix a batch for her from one or two of the above.

 

Also, I have 3 or so other glazes I'm hoping to test fire this coming week. I have some ideas based on Marcia's suggestion in an other thread.
