響を受けて発生し、再現の難しい焼成であつた。Conventional technology Bizen ware did not use glaze, but instead used a climbing kiln to give the surface of the ceramic a kiln pattern such as sesame, scarlet, sangiri, or peony. It may occur in a specific area in front of the fire, or if semi-finished ceramic products are baked in layers and the flames and ash do not touch that area, or if semi-finished ceramic products come into contact with cold air or water vapor for a long period of time during firing. The surrounding area was affected by different temperatures and gases than other parts, and the firing was difficult to reproduce.

Even if a wonderful kiln change occurs once, even if semi-finished pottery is piled up in the same place in the climbing kiln,
There is no guarantee that you will be able to obtain the same changes in the kiln twice, and this process has simply been repeated. Furthermore, the soot and smoke emitted from climbing kilns pollutes the environment (air) where local residents live.

模様を与えるものである。 The FD burner 11 is an abbreviation for Flame Diffusion, and is made by providing a large number of small pores in a refractory material.
A mix of gas and air is ejected and burned through these pores, which significantly reduces the combustion space (a partial cross section is shown in Figure 3), reduces the amount of heat radiated from the burner body, and makes the entire burner surface red hot. By doing this, the ceramic semi-finished products can be uniformly heated by radiation. After placing the firing table brick 44 on the combustion chamber hearth and arranging the ceramic semi-finished products on top of it, the combustion chamber door 22 is closed and the pilot burner 23 is ignited.
When the temperature rises to ~250℃, the FD burner is ignited, and when the temperature rises further to 1100~1200℃ and the surface of the ceramic semi-finished product begins to melt, the flame burner 24 is ignited and the spraying agent is added to this flame. It is sprayed onto the surface of semi-finished ceramics to change it in a kiln, giving it color, luster or pattern.

つやあるいは模様を変化させることができる。Function This invention uses an FD burner in which a large number of small pores are provided in the refractory at a small pitch, and a mixture of gas and air is ejected and burned from these pores, so the combustion space is significantly reduced. , by reducing the amount of heat dissipated from the burner body, the entire burner surface becomes red hot and can be heated uniformly by radiation, and by adding a spraying agent to the flame that forms the flame burner at the end of firing the ceramic semi-finished product, it can be applied to the surface of the ceramic semi-finished product. It gives an exquisite kiln change. in this way,
When using an FD burner, it has the ability to heat uniformly even if the distance between the ceiling and the object to be heated is around 100 mm (less than 1/10 of a climbing kiln) using plane radiation, and it also has the ability to heat uniformly even if the distance between the ceiling and the object to be heated is around 100 mm (less than 1/10 of a climbing kiln). The color of the ceramic surface varies depending on the composition of the spray powder added to the flame.
The gloss or pattern can be changed.

図に示し、その他の条件を次に示す。Example In FIGS. 1 and 2, the firing chamber 4
The ceiling of 3 is constructed with 11 FD burners,
The FD burner 11 has a large number of mixed gas supply pores 30
(as shown in Figure 3), and in the case of this example, there are 190 mixed gas supply pores (19 vertically and horizontally x 10 = 190).
They are arranged at the same spacing. A required number of flame burners 24 are provided on the side wall of the firing oven for spraying sawdust or the like onto the surface of the ceramic semi-finished product depending on the shape or quantity of the ceramic semi-finished product. First, LPG is released from the pilot burner 23, and after ignition, air is sent to adjust the firepower, and the temperature is raised until the atmospheric temperature in the kiln reaches 200 to 250℃, and then F.
Light D burner 11 and start baking in earnest. When the atmospheric temperature inside the kiln reaches 1100°C, LPG is sent to the flame burner 24 to ignite it, oxygen is sent to adjust the firepower, and sawdust is fed at a speed of 10/hr, which is then pumped with LPG. By burning it in a flame and spraying it on the surface of a semi-finished ceramic product at an oxygen to LPG ratio of 0.8 until the end of firing, it was possible to create a sesame pattern on the surface of the ceramic, similar to that produced by burning pine wood in a climbing kiln. did it. The temperature rise curve at this time is the seventh
