What raw materials are used by Mtarfa Glassblowers?

Mtarfa Glassblowers uses standard glassmaking raw materials, including silica sand, soda ash, and limestone. These are melted together to form molten glass. Colour is introduced through metal oxides, such as cobalt for blue and iron for green. Small amounts of recycled glass, known as cullet, may be added to improve melting efficiency. The furnace operates at high temperatures, often above 1,000°C, which requires steady energy input. Material quality affects clarity and strength, so suppliers are chosen with care. The finished glass remains non-porous and resistant to most chemicals found in daily use. This makes it suitable for decorative items and some functional pieces. The balance of materials has changed little over centuries, showing how traditional methods remain effective.
