Description
Technical field
The invention belongs to the Longquan celadon manufacture technology field, relate to a kind of Longquan celadon pad firing technique.
Background technology
At present, the pad firing technique of Longquan celadon adopts mud cake, aluminum oxide cake, support pin etc. directly to fill up burning more, there is obvious pad burning vestige at pad burning position, yielding, appearance effect is not good, largely affect the appearance effect of the especially high-end celadon of celadon, be difficult to promote making quality, the artistic grade of Longquan celadon.All the time, be the problem that vast celadon practitioner explores always to improvement and the innovation of pad firing technique.
Summary of the invention
The purpose of this invention is to provide a kind of Longquan celadon pad firing technique, overcome the defective of Longquan celadon goods of the prior art on pad burning effect, make bedder with the raw material of making base that shrinkability is identical, and pad is burnt the position decorate, make it after firing, fire vestige without obvious backing.
The technical solution adopted in the present invention is: a kind of Longquan celadon pad firing technique, it is characterized in that, and will fill up the burning position and carry out the processing of grain pattern decoration, may further comprise the steps:
1. moulding: according to design requirements, make the celadon moulded pottery not yet put in a kiln to bake;
2. dry: as the celadon moulded pottery not yet put in a kiln to bake of making to be carried out drying treatment, reach semiarid degree;
3. repaired biscuit: according to design requirements, with the refine of semiarid celadon moulded pottery not yet put in a kiln to bake, but especially pad burns the position and needs according to design requirements finishing decorative zones;
4. pad burns the decoration at position: according to the processing requirement of celadon goods, the pad on the celadon moulded pottery not yet put in a kiln to bake is burnt the position decorate, obtain the celadon carcass;
5. the making of bedder: use the raw material of making base identical with the celadon moulded pottery not yet put in a kiln to bake to make bedder, bedder is processed, make itself and celadon carcass need fill up the burning spot size and fit like a glove;
6. biscuiting: dried celadon carcass and bedder are put into kiln, fired 5-6 hour, make kiln temperature rise to gradually 750 ~ 780 ℃ from normal temperature, and then continue insulation 10-20 minute, flame-out naturally cooling obtains celadon biscuiting tire;
7. glazing: celadon biscuiting tire is carried out glazing, need fill up after the glazing and burn top layer, position glaze scraped clean;
8. glaze firing: the pad on bedder and the celadon biscuiting tire is burnt position placements that fit like a glove, put into together kiln and carry out twice firing, through 8-12 hour fire, end the fire cooling after making kiln temperature reach 1280 ℃, obtain filling up and burn the intact celadon goods of position decoration.
The present invention is owing to having adopted above-mentioned technical scheme, realized the technological breakthrough that the seamless pad of Longquan celadon burns, and by this pad firing method, to fill up the burning position and carry out ingenious decoration, can produce exquisite Du Genggao, the better high-end celadon goods of visual effect, break through Longquan celadon and can't utilize the ring foot position as the limitation of decorative art innovation, found new direction for the innovation of Longquan celadon pad firing technique, enriched celadon decorative art intension.Manufacture craft is simple, by artificial or mould molding, pad is burnt the position decorate, realize scale operation, both realized artistic value, improved simultaneously the celadon quality, make the celadon decorated style to development in pluralism, further promote the status of Longquan celadon in whole ceramic industry.
