Topics I've Started

Deflocculated Wax Resist?

12 January 2015 - 09:40 PM

on another thread, someone suggested that I add some food coloring to my wax resist so I can see what I have coated. Seemed like a good idea to me.

 

after stealthing into the kitchen to steal my wife's red food coloring, I added a few drops to my axner wax resist. it immediately went from a thick paste to a runny liquid like you would expect a glaze to change if you added sodium silicate to it. Is this what should happen? Should I be using some special type or brand of food coloring to keep it from happening?


Keeping Casserole Lids From Sticking During Glaze Firing

08 January 2015 - 03:54 PM

When you glaze fire a casserole or other lid on its associated pot, there's always the risk of glaze running and welding the lid to the pot. 

 

Has anyone ever tried putting a little kiln wash on the contact area between the lid and pot?


High Ball Clay Cone 6 Glaze

28 December 2014 - 04:58 PM

 I'm fiddling with the idea of doing mocha diffusion over the top of glazes so that they come through sharper. To do this, I need a reliable very high ball clay cone 6 glaze as a starting  point for further adjusting it with insight.Aany recommendations would be appreciated


Robin Hopper's Mocha Diffusion-Base Slip

17 December 2014 - 06:43 PM

in the article of Robin Hopper demonstrating mocha diffusion, he gives the following formula for his base slip.

 

Feldspar       5%

Ball Clay     75%

Kaolin         10%

Silica           10%

 

 

does anyone know what kind of feldspar,and  ball clay, one should use?

 

Also I'm trying to get mocha diffusion to work and having very little success

 

  I read a number of descriptions, including Robin's on the web. However, I'm not having any luck getting the dendrite pattern. I have a lot of things and nothing seems to make much difference. 
 
This is what I've tried:
 
1. Slip made of Tennessee ball clay
2. One of Robin Hopper's diffusion slip: (ball 75, spar 5, silica 10, epk 10) plus I add 5  3134 and 10 RIO
3. adding hardwood ash, or sodium silicate, or Calcium nitrite, or amonia to the above slips
 
I've used thick and thin solutions of cobalt carbonate and ordinary vinegar or apple cider vinegar.
 
I've tried using in both horizontally and vertically on my leather hard G6 mix clay.
 
The very best I've done is to get some almost microscopic dendrites on the edge of my dribbles.
 
I would appreciate any advice or guidance you can give me in debugging this.
 
Thanks

Stephen Hill Firing Schedule

24 April 2014 - 04:44 PM

One unique feature of Stephen Hill's firing schedule is that he goes to someplace in ^ 5 then holds for up to an hour until the ^ 6 drops.  what is the point of this versus simply going to cone 6?
