AGI的着色前池是生产有色玻璃的一种有利方法，而不必改变整个熔炉的颜色。优点是有两种颜色同时和一个临时着色过程的可能性。
彩色前炉技术是非常灵活的，允许在一个广泛的颜色，包括容器，餐具和化妆品容器的全系列产品。
着色前室的设计取决于所需的容量，并与中心线辐射冷却或中心线空气冷却一起工作。两者都代表了当今最先进的前炉设计技术。耐火结构设计是一种最新的现代建筑，采用当今所有的技术来实现均匀的颜色分布，同时具有高的热均匀性和最低的能源要求。

优质耐火材料用于槽块，槽块周围有适当级配的绝缘材料。
上部结构的屋顶块由不同种类的耐火材料制成，以实现较长的使用寿命。着色工段采用高密度、低孔隙率的特殊粘结铝锆耐火材料（锆英-莫来石），采用高腐蚀性着色剂，冷却工段采用硅线石材料覆盖。盖块具有特殊形状，以在采空区点实现最高温度均匀性。
前室根据所需颜色、吨位和现场条件分别设计。所有的前院通常由
- 加热和加药区
- 搅拌区
- 冷却区
- 调节区。
对于加热和加药区，AGI提供精确的工作称重系统，将准确数量的着色剂添加到玻璃表面。随后的搅拌区配有多个搅拌装置台，用于将着色剂与碱性燧石玻璃混合。
在着色前室最重要的是一个稳定的气体/空气混合物加热系统，以不影响颜色，特别是还原气氛中的颜色。因此AGI提供了精确的混合CORA系统。此外，可以安装lambda控制器来调节气体/空气混合物中的实际氧含量。
AGI的着色前池系统应用于多种玻璃行业，如容器玻璃、餐具或平板玻璃生产。
