Slip Trailing Slip   cone 04-10

-I use a higher temperature clay body than I am firing to (e.g. cone 10 porcelain for cone 6 slip trailing slip and for cone 04 slip trailing slip), almost always a “porcelain” to make a thick, slip trailing slip.

to mix:
-slake down clay body to a heavy cream-yogurt consistency
-add 1 tsp Soda Ash per 4 cups slip trailing slip, let sit 10 minutes, mix well, screen through at least 60-80 mesh sieve
-fill slip trailing bulb, Enjoy!

-for Green add 1 Tablespoon of Copper Carbonate per 1 cup slip
-for Blue  add 1 tsp of Cobalt Carbonate per 1 cup slip

Pete Pinnell’s (modified) Easy-Peasy Terra Sigillata  (multiply the recipe by 3 to get around 3 gallons of sig)

Clay*                                      1500grams
Water                                           1 gallon            
Sodium silicate                         1 tablespoon            

*for juicy orange-red:  Newman Red Fire Clay
  for brown-red:  Redart
  for white to orange blushing:  XX Sagger
  for white to yellow blushing:  OM4 Ball Clay


1)    Slake clay into water and blend well.

2)    Add sodium silicate and blend well.

3)    let sit 20-72 hours (20 hours for ball clays, 3 days for Newman Red)

4)    pour off top layers until you get to thicker chunkier stuff

5)    You want to keep the top layers, should be thin like skim milk, this is your terra sig. You can toss the thick chunky stuff.  You can leave it uncovered and let the water evaporate off.  If brushing, 3 coats on bone dry work. If dipping, also on bone dry, 3 coats will give you a nice eggshell surface without burnishing.  

-add stains and oxides for different colored sigs, usually around 1 cup of sig to
 1 tsp -1 tablespoon of colorants.  Add colorants to the already decanted sig. 

Butter (White to Yellow) add 1 Tbsp Titanium Dioxide to 1C White Terra Sig

Blue add 1 tsp Cobalt Carbonate + 1 Tbsp Titanium Dioxide to 1C White Terra Sig
