また、本願では、ガラス製品10を製造する方法が提供される。当該方法は、フロートプロセスにより、ソーダライムガラスの第1のペインを形成するステップを有する。第1のペインは、1.1から4.0mmの厚さを有する。第1のペインは、前述の任意のものであってもよい。また当該方法は、フロートプロセスにより、ソーダライムガラスおよび/またはアルミノシリケートガラスの第2のペインを形成するステップを有する。第2のペインは、0.3から1.05mmの厚さを有する。第2のペインは、前述の任意のものであってもよい。フロートプロセスは、よく知られており、即時の開示において、フロートプロセスのいかなる1または2以上のステップが利用されてもよい。
車両のフロントガラスとして、5つのガラス製品を製造した。ガラス製品の2つ(製品1および2)は、本願の実施例を表す。ガラス製品の3つ(比較製品1、2、3)は、本願の実施例ではなく、実質的に垂直なドローラインを含まず、比較例として評価した。
本データでは、驚くべきことに、厚さ(t2)が約0.70mmの極めて薄いガラス(UTG)を有し、実質的に垂直なドローラインを有する製品1、2が、優れた点光歪み品質を示すことがわかった。換言すれば、製品1、2は、驚くべきことに、当業者に予想される結果とは反対の優れた光学特性を示した。
