To make the green-sand mould the sand must be properly tempered before it can be used. If the sand is too dry, additional water is added if too wet, dry sand is added until it has the proper temper. To check the sand for proper temper, a handful is grasped in the first. The pressure is released, and the sand is broken in two sections.
The simplest way to make it was using green sand. Although it should be the best way for casting, it demanded to make a flask. Flask is a frame for the mould. It keeps all green sand inside. It consists of two parts: 1. Upper part is called a cope; 2. Under part is called a drag. To make a flask we need one long or several short planks.
