I’ll be doing a barrel fire soon- when the burn ban lifts!
But I’m getting the pots ready.
Here’s a video on how I do it:
To prepare pots for barrel firing, each vessel must be sanded, terra sigillata applied, then burnished to a high shine.
I use Marcia Selsor’s recipe for Terra Sigillata:
Fill a liter plastic bottle 3/4 full of water.
Add 250 grams of ball clay.
Put lid on bottle and shake vigorously.
Add about 1 teaspoon of sodium silicate to bottle.
Shake vigorously again.
Let bottle sit for an hour.
Put bottle in a container wider than the bottle.
Put a slit in bottle just above dark portion of contents and squeeze to get the liquid terra sigilatta out.
Put terra sigillata in covered container.
It’s so easy!!
I’m available for workshops- just let me know at marianhwilliams@mac.com
Peace out, potters!
