How Many Water Colors Besides Cobalt Withstand Firing?

15 July 2016 - 02:41 PM

I have noticed a couple of posts mentioning the use of "cobalt  blue watercolor" as a colorant in glazes and washes. Are there other watercolors that are fire stable that would be usable as washes or in glazes?

Is It Possible To Make A Hydrophobic Glaze?

17 June 2016 - 01:10 PM

I was watching a YouTube video on water marbling/

 

   

 

In it Garip Ay makes water marbling pictures useing oil paints on ink stained water.  He then lays paper over the surface a gets an oil painting transfer.   If one could make hydrophobic glaze, could you imagine what transfers one could produce?

 

1.  Could water be replaced by mineral spirits in a glaze?

2.  Would this mineral spirit glaze float on water?

3.  Has anyone ever tried water marbling with a hydrophibic glaze?

Mixing Clay Bodies To Get Desired % Shrinkage

01 June 2016 - 11:14 AM

I just got an old (new to me) Brent extruder and will be making a lot more flutes.  But I am getting tired of the calculations for 12% shrinkage rates.  So I bought some heavily grogged Dixon Sculpting clay from Aardvark that has 8% shrinkage at cone 5.  

 

1.  Can I  mix that with B mix in a 50-50 mixture to get a clay body that shrinks 10%?  

 

2.  Does anyone know how these two clay bodies might play together?

 

The Dixon is Terra cotta red color in oxidation at cone 5. B mix at cone 5 is white.

 

3.  Any guesses as to what color the mix might be?

 

I thought if anyone may have tried this I could get some useful information.  Otherwise, I will try mixing them and see what I get.

Does anyone here have a diagram of the brent slab roller cable system. I want to replace the old cables. The current ones are getting frayed.
