All glass products from LSA are handmade and produced from soda-lime glass - which unlike crystal is lead free. The ingredients are primarly made up soda ash, lime and sand. Creating this 'recipe' and scientifically mixing the ingredients in the correct proportions is a difficult and skilled task and it ensures that the color, texture, consistency and clarity of the finished piece is exactly as desired.

The mixture is heated up in a gas-fired kiln to several hundred degrees. Bubbles of air can occasionally get trapped within the molten glass during this process and these bubbles can sometimes be seen in the finished product - a normal and acceptable part of the process of making handmade and mouthblown glass.
