5 lbs. Leopard Spot Shino Cone 10 Reduction
Description: This is NOT a typical Shino and it requires special handling for the best results. Be sure to follow the instructions below. Be sure to run a few tests before applying any unfamiliar slip or glaze to lots of work. Take notes. Find the correct application for your work with the way your kiln is being fired. One order includes 5 lbs of dry Leopard Spot Shino. This makes approximately 1 gallon plus of glaze. write to email@example.com if you have any questions.
Application: Bisque Temperature Makes a Difference in Application: If you're working in a cone 10 Porcelain or BMix you'll want to bisque to 08. We're not sure how it will work on stonewares with lots of grog. This glaze does not work on Vegas Buff.
What you'll need: A metal bowl or cooking (lobster) pot. A long metal or wooden Spoon to stir with. You can also do this on the stove top and "cook" the shino "Mudd" to melt down your soda ash.
1) Add enough Hot Water to this shino to make it slightly thick like mud and stir. (You're melting the soda ash). Keep stirring. Let cool naturally overnight with a lid on it to allow most of the soda ash in the shino formula to melt.
2) Then, add a bit of room temperature water and mix well and check it with a Hydrometer. This Shino works best if it's water content is at 40-42 on a hydrometer. Keep adding a bit of water and mix and measure it with the hydrometer until you get it to a 42 on the hydrometer scale. Once your shino is mixed you don't need to do this part again. Just stir it before you dip. So far, our first batch of Leopard Spot Shino has worked great for over a year. Be sure to keep it covered with a lid when you're not using it.
If your pottery is bisque-fired to cone 08: Dip for a medium count of 6 to 10. Everyone counts at a different speed. So, start to pull out slowly at 6 and finish by 9 or 10. The tall cylinder in these images shows where the leopard spot is thinner at 6 and it's orange. By the end of the dip it's a count of 10 and it's black where it's thicker.
NOTE: This Leopard Spot Shino Does NOT work if it's sprayed on.
Cover your work that's been glazed with shino with a plastic sheet to slow down the Soda Ash from coming to the surface. Uncover the pots when you're ready to load and start the kiln. We've had pots glazed with shino that have sat under a plastic sheet for weeks before loading a kiln and the work has fabulous spots on it.
Wadding The Feet: With a "Dipping" Shino the soda ash seeps into the body of the bisque and, even though you've wiped off the foot, it will still come thru the bisque and stick to the shelf. It's best to Wad your feet like when firing in Wood Fire or Soda Firing. Any good wadding formula will work. And, we sell Wadding on this website. The page also includes instructions for Wadding your work.
Loading and Firing Instructions: Fired in cone 10 reduction. Fire this Shino in a normal reduction atmosphere.
Important Loading and Firing information:
1). Do Not over-reduce this Shino because the carbon is already in the formula. A lot of people over reduce their kiln. A rise of 180 degrees per hour is plenty of reduction when you're in reduction. Tom Coleman is firing a Geil Kiln and has a 6 inch flickering flame out the flue when in reduction. All the glazes are so much better when fired in a medium to light reduction.
2) Do Not load your Leopard Spot Pots next to the outer part of the shelves near the burner side. Loading them toward the center and up the front of the kiln are good places for your Leopard Spot Pots. Be sure to take notes as to where your kiln gives you the best results. Each kiln fires differently. And, each Potter fires their reduction a little different.
