True Japanese Raku refers to pottery made by a specific family in Japan for pottery that is specifically made for the Japanese Tea Ceremony. This article will discuss Western-style Raku, developed by Paul Soldner in the 1960s.

  1. These glazes have a low melting point so they will mature at cone 06 in about an hour.***note: many of these glazes work better of applied in a thin layer***
    • It is better to wax the bottom if you dip and glaze the objects to prevent the glaze from getting onto the part that touches the kiln shelf.
    • If you brush and glaze, you need not wax it because you can control where exactly you are putting the glaze.
    • You can use a soft bristle brush and follow the manufacturer's directions for the product you are using. Let one coat dry before applying the next one.
  2. This should take about an hour. If you don't know how to fire a kiln, you should have an experienced potter help you. [1]
    • If you are using pyrometric cones or a pyrometer, skip this step.~~ Check on the ware every 15 minutes or so after you've been firing for about 45 minutes. You're looking for bubbling in the glaze. Once it starts bubbling, you're about 15 minutes away from "Raku Time!"

  3. Matt glazes are more difficult to read, so fall back on your cones/pyrometer reading if you need to.
  4. The cans should only be a little bigger than the pieces you want to put in them, the smaller the better to create a good reduction and lots of pretty color!
  5. (1)One to open the door, (2)one to pull the pieces out with tongs and place them in the cans, and (3)one to close the can lids. Each person should have a set of Raku gloves and appropriate eye protection. You may also want to wear dust masks as it's gonna get smoky!
  6. The door should be closed between pulls to retain heat. Place the pieces as quickly as possible into the waiting cans. Person 3 should wait for the newspaper to catch fire, then fit the lids on securely to smother the fire and smoke the pieces. **Note, always try to turn bowls upside down so the inside gets better color**
  7. Good cans shouldn't release too much smoke when covered, so be careful when you open them up. Keep your face away from the openings as you take off the lids. Also watch out for back drafts.
  8. Any remaining newspaper will begin to burn again once air is introduced back into the can. You can pour some water into the cans to put them out and cool the ware.
  9. **DO NOT DO THIS TO BOTTLES*** Bottles will explode if you douse them, allow bottles to cool naturally.

  • Question
    Can sawdust be used?
    Community Answer
    Yes, but shredded paper can give you a cleaner surface. Sawdust can stick in the glaze, but gives nice effects as well.
  • Question
    Should this be done indoors?
    Community Answer
    For safety, you should do it outside, wear a mask, gloves and perhaps safety goggles.

      Tips

      • Try different glazes on different parts of the same piece, the results are amazing!
      • Use spray fix on shiny metallic glazes to keep them from oxidizing and losing their color over time. Some color can be revived by putting in direct sunlight for a period of time.
      • A little sawdust in the cans will increase the smoke if you're using a White Crackle glaze. Again, make sure you place the Crackle side down in the cans to get good smoke lines

      Warnings

      • People sensitive to smoke should probably not Raku.
      • Only use real ceramics gloves. These gloves are rated to 1700 degrees. Your lobster oven mitt is not gonna cut it.
      • This is very dangerous, please only Raku under the supervision of an experienced Potter.
      • Pieces come out of the cans at well over 1000 degrees, even though they look cool. Always use gloves and tongs to take pieces out of the cans. [2]
