界首彩陶为二次烧制，先素烧再釉烧。两次烧制的温度差别不大，其中素烧时温度略低于釉烧所需温度。
Jieshou Colored Pottery undergoes a two-stage firing process: the bisque firing followed by the glaze firing. The temperature difference between the two stages is minimal, with the bisque firing conducted at a slightly lower temperature than the glaze firing.
素烧·Bisque Firing
土窑烧制素坯的时间通常在12～20小时。点火后，先升温至400℃，排除窑炉和泥坯中的湿气，以避免后续釉烧时产生“桔釉”“气泡”等缺陷。温度超过400℃后，即可封闭窑炉，升温至700℃～800℃，保持温度1小时后，即可停止烧窑，自然降温。
The bisque firing takes place in an earthen kiln and usually lasts between 12 to 20 hours. The process begins by gradually heating the kiln to 400°C to remove any moisture from both the kiln and the clay piece. This step is crucial to prevent defects like "orange peel" texture or bubbling during the subsequent glaze firing. Once the temperature exceeds 400°C, the kiln is sealed and the temperature is raised to 700-800°C. After maintaining this temperature for about an hour, the firing process is halted, and the kiln is allowed to cool naturally.
点绿釉·Applying the Green Glaze
素烧后，界首彩陶通常会用铜釉作为装饰。经过高温烧制后，铜釉呈现鲜艳的绿色，与红白两色一起，形成界首彩陶红白绿的典型三彩配色。铜绿釉乃三彩中的点睛之笔，在陶器表面形成流光溢彩、自然灵动的釉色。
After the bisque firing, Jieshou pottery is typically decorated with a layer of copper glaze. When fired at high temperatures, this copper glaze transforms into a vivid green, adding a striking contrast to the red and white hues. The green glaze serves as the final flourish of Jieshou's tri-color palette, creating a shimmering, lively effect on the pottery's surface.
釉烧·Glaze Firing
界首彩陶属于低温釉陶，所用釉料为当地配置的透明铅釉，烧制前为鲜艳的橙红色，烧制后透明无色，釉面厚度较薄、光泽度较高。将釉料加水调制成釉浆，采用淋釉法对素烧后的陶器进行施釉，再经过一两天的干燥，即可放入窑炉进行釉烧。釉烧的工序和素烧一致，烧制温度控制在1000℃左右，烧制两天两夜。
Jieshou pottery is classified as low-fire glazed pottery, using a locally prepared transparent lead glaze. Before firing, this glaze appears as a vibrant orange-red; afterward, it turns clear, providing a thin yet glossy surface. The glaze is mixed with water to form a slurry and is applied to the bisque-fired pottery using the pouring method. After drying for one to two days, the piece is placed in the kiln for the glaze firing. The process mirrors that of the bisque firing, with the temperature controlled at around 1000°C, lasting for two days and nights. The result is a lustrous, tri-colored piece that embodies the tradition and artistry of Jieshou Colored Pottery.
