陶瓷生产工艺详细流程:
坯釉原料进厂后,经过精选、淘洗,根据生产配方称量配料,入球磨细碎,达到所需细度后,除铁、过筛,然后根据成型方法的不同,机制成型用泥浆压滤脱水,真空练泥,备用;对于化浆工艺,把泥浆先压滤脱水,后通过加入解凝剂化浆,除铁、过筛后备用;对注浆成型用泥浆,进行真空处理后,成为成品浆,备用。
成型工序:分为滚压成型和注浆成型。然后干燥、修坯,备用。
烧成工序:在取得白坯后,入窑素烧,经过精修、施釉,进行釉烧,对出窑后的白瓷检选,得到合格白瓷。
彩烤工序:对合格白瓷进行贴花、镶金等步骤后,入烤花窑烧烤,开窑后进行花瓷的检选,得到合格花瓷成品。
包装工序:对花瓷按照不同的配套方法、各种要求进行包装,即形成本公司的最终产品,发货或者入库。
陶瓷的干燥是陶瓷的生产工艺中非常重要的工序之一,陶瓷产品的质量缺陷有很大部分是因干燥不当而引起的。陶瓷的干燥速度快、节能、优质,无污染等是新世纪对干燥技术的基本要求。

陶瓷工艺制作流程如下:
1、练泥。从矿区采取瓷石,先以人工用铁锤敲碎至鸡蛋大小的块状,再利用水碓舂打成粉状,淘洗,除去杂质,沉淀后制成砖状的泥块。
然后再用水调和泥块,去掉渣质,用双手搓揉,或用脚踩踏,把泥团中的空气挤压出来,并使泥中的水分均匀。
2、拉坯。将泥团摔掷在辘轳车的转盘中心,随手法的屈伸收放拉制出坯体的大致模样。拉坯是成型的第一道工序。拉坯成型首先要熟悉泥料的收缩率。
3、印坯。印模的外形是按坯体内形弧线旋削而成的,将晾至半干的坯覆在模种上,均匀按拍坯体外壁,然后脱模。
4、利坯。将坯覆放于辘轳车的利桶上,转动车盘,用刀旋削,使坯体厚度适当,表里光洁,这是一道技术要求很高的工序。利坯,也称“修坯”或“旋坯”,是最后确定器物形状的关键环节,并使器物表面光洁、形体连贯、规整一致。
内外修坯是景德镇制瓷工艺中一个极为重要并优于其他窑系的成型技术,是形成景德镇陶瓷风格的一个独特的技术保障。
5、晒坯。将加工成型后的坯摆放在木架上晾晒。
6、刻花。用竹、骨或铁制的刀具在已干的坯体上刻画出花纹。
7、施釉。普通圆器采用醮釉或荡釉。琢器或大型圆器用吹釉。大部分陶瓷制品均需经施釉后才能进窑烧造。施釉工艺看似简单,却是极为重要和较难掌握的一道工序。
要做到坯体各部分的釉层均匀一致,厚薄适当,还要关注到各种釉的不同流动性,实在不是件容易的事。
8、烧窑。首先把陶瓷制品装入匣钵,匣是陶瓷制品焙烧的容器,以耐火材料制成,作用是防止瓷坯与窑火直接接触,避免污染,尤其对白瓷烧造最为有利。
9、彩绘。釉上彩如五彩、粉彩等,是在已烧成瓷的釉面上描绘纹样、填彩,再入红炉以低温烧烘,温度约700—800度。

Ceramic processOne, wash kaolin is the best raw materials for firing porcelain, for thousands of years, how many high-quality goods ceramics are from these humble clay evolved, the first process porcelain: Amoy mud, is to wash into usable porcelain clay. Two, pile of mud Amoy good porcelain clay could not immediately use, to separate, pile into the column, to facilitate the storage and the use. Three, the good will of porcelain clay into a large turntable, by rotating the turntable, hands and drawing tools, will pull into a porcelain porcelain clay. Four, Indian slab pull porcelain good is only a prototype, but also need to do shape selecting different impression will porcelain printing into various shapes. Five, trimming the freshly printed rough uneven thickness, through the process of trimming printed blank shaving neat and trim. Six, Na Na water water is an essential procedure, namely, use clean water to remove the dust on the blank, prepare for the next draw billet, glaze etc.. Seven, paint painting blank in blank is one of the characteristics of ceramic art, painting blank has many kinds, a style, a good paste paper sketches, no matter how painting blanks are ceramic process punchline. Eight, glazed porcelain painting good, rough and Daise, good glaze is completely different, smooth and bright: glazing technique is different, have different effect. Nine, kiln the Millennium kiln fire, which does not stop, after dozens of tools carved fine porcelain, subjected to thousands of degrees firing in the kiln, just like an ugly duckling into a beautiful swan will reach. Ten, after several days of Shaolian porcelain, porcelain kiln has become pieces of fine porcelain, from the open door to talent showing itself unable to hold oneself back kiln.
