Green Soap And Drape Molds

28 April 2015 - 09:13 PM

I am trying my first experiments using a drape mold. 

 

There seem to be a number of options:

1. Bisque the mold then lay the clay over it

2. Bisque the mold then rub a layer of green soap on it before laying the clay over it

3. Fire the mold to glaze temp with no glaze then lay the clay over it

4. Fire the mold to glaze temp with no glaze then rub a layer of green soap on it before laying the clay over it

5. Fire the mold to glaze temp with glaze then lay the clay over it

6..Fire the mold to glaze temp with glaze then rub a layer of green soap on it before laying the clay over it.

 

 

What are my trade offs for these strategies? Or is there a better way to go? Or????

 

Thanks


Brushing Glaze Smoothly

20 March 2015 - 11:32 PM

I usually spray on glazes. Recently, I made some shapes much too complicated and restricted to get even an airbrush in position to spray. The only alternative I can see is brushing on glazes.  However, my glaze brushing looks like a four-year-olds fingerpainting. Can someone explain how to get very nice smooth glaze application with a brush, or point me to an article that lays it out.


What Grit For Diamond Pot Bottom Smoother

I'm about to build a  10 inch diamond grinder to smooth the bottoms of my pots. It will have continuous water flow over the disk. What grit would you recommend?


Sarah Hillman Glazing

I love some of Sarah Hillman's pots, http://www.sarahhillmanceramics.com/  .I would like to try making some stuff like that, but I don't understand how she gets such a sharp edge between the inside and outside glaze. Can anyone explain how one does this?


Stephen Hill's Watercolor Green Pitting

15 February 2015 - 02:13 PM

From time to time I'm having problems with Stephen Hill's watercolor green pitting. It's not as bad when I put it over SCM.  Sometimes it's just fine. In all cases, I'm using G mix 6 w/ grog Fired to cone 6. All the results are from the same small batch of glaze.

 

This is the formula that I'm using

 

Water Color Green (Cone 6)

 

 

Custer ...         47.8 

Silica ...          16.9

Lithium Carb ... 4.0

Frit 3124 ...      5.0

Whiting ...       16.0

Strontium Carb ... 7.5

Bentonite ...      2.9

Copper Carb ... 8.0

 

 

 

As a side note, on one pot the pitting actually looked pretty cool since it was very evenly distributed and the color was darker around each pit. Not what I would have planned but an interesting result.
