The first room of the tour is the mould room, where moulds are made out of beach or pear wood. These wooden moulds are generally used for special orders or when developing a new product. Even though beach and pear wood withstand heat incredibly well, the moulds usually only last between 7 and 10 days. Pieces that are produced often, like things you would find in their catalogue, would be made in cast iron moulds instead.

Next you enter the blowing room where the crystal actually takes shape. The furnaces heat the molten crystal to 1300°C (2372°F). Once the crystal is red hot, the blowers remove it from the furnace and use wooden tools and their lungs to shape the crystal before putting it in the mould. Once the crystal cools to its normal clear color the piece is removed from the mould, checked for impurities, and is off to the kiln to slowly cool to room temperature.
Once the pieces are fully cooled they go through a series of quality checkpoints. If they have any slight imperfection, they are smashed and remelted for another go round. The pieces then go to be marked for cutting. A temporary pattern is drawn on each piece that later gets cleaned off during the washing and polishing stage.

What's really cool about this room of the tour is that the Master Cutters will actually talk to you and tell you what they're working on. One Cutter named Brendon chatted with Molly, Joy,and I for quite a while. He talked with us about the differences between machine cuts and cuts done by hand. Horizontal cuts along rounded objects are difficult and time consuming for the Cutters so they often have the machines do these. The machines also do circular cuts, which is what is happening in the picture below.
