Abstract

$Zn_2TiO_4$, which is a progenitor of zinc crystallization, plays a significant role in controlling the crystallization of willemite ($Zn_2SiO_4$) in forming glaze at low temperatures. Thus, $Zn_2TiO_4$ was used to formulate stable willemite and to gain structural control. When synthesized 15 wt% of $Zn_2TiO_4$ is added to engobe and then applied, it can manipulate its crystallization and location. Additionally, when colorant is added to $Zn_2TiO_4$ and then applied to engobe, the mixture's colorant effect can be shown at crystallization. Certain characteristics of synthesized $Zn_2TiO_4$ enable various engobes to be applied to clay bodies. With a single glazing, the crystallization, location, and color of the crystals can be discretionarily regulated.

Anatase 형 $TiO_2$에 의해 저온에서 생성되는 $Zn_2TiO_4$는 willemite($Zn_2SiO_4$) 결정 전구체로 유약 내 willemite 생성에 매우 큰 영향을 준다. 안정적인 willemite 생성 및 위치 제어를 위해 $Zn_2TiO_4$를 활용하였다. 합성된 $Zn_2TiO_4$를 화장토(engobe)에 15 wt% 첨가하여 도포하면 유약 내에 결정의 생성과 위치를 조절할 수 있다. 발색제가 고용된 $Zn_2TiO_4$를 화장토에 적용하면 결정부분에만 발색효과를 얻을 수 있다. $Zn_2TiO_4$를 화장토(engobe)로 적용하면 한 번의 시유로 결정의 생성유무와, 위치, 색상 등을 임의로 조절할 수 있고 유약의 장식 효과를 높일 수 있다.
