The Company

We are a small company based in Wiltshire, England, producing hand-built mobile glassblowing furnaces. The very first furnace was developed by KT Rothe, our founder, so that she could continue glassblowing during maternity. KT’s sister company The Glass Hub, a glass education centre, has used only Minimelt furnaces for all of their hot glassblowing courses since 2012, proving their robust build and longevity.

The Minimelt is designed specifically for rapid melting, allowing for impulsive glassblowing, where time and cost are kept to a minimum. It is perfect for prototyping ideas, small production runs, training, mobile demonstrations and teaching.

The Furnace

The Minimelt is a bespoke, hand-built piece of equipment, consisting of a steel drum, lined with ceramic fibre insulation, sitting above an insulated box containing the melting pot. The Drum is detachable so that the pot can be replaced. We recommend the Minimelt is emptied completely at the end of a session, to ensure a longer pot life. When done properly, a pot will last for well over 50 melts before needing to be changed.

The furnace and frame is made of quality stainless steel that will last a lifetime, and has wheels front and back, for manoeuvrability. It is fully transportable, small enough to stow away when not in use, and with running costs that are very low compared to regular glassblowing studio equipment.

How it Works

The Minimelt is a mobile glassblowing unit that combines the melting capacity of a furnace with the reheating aspects of a glory hole, thus saving both space and energy. A bespoke melting pot is filled with glass which is heated by a simple burner attached to a gas bottle. The glass heats, melts and can be ready to blow in as little as two hours.

Because the glass melts rapidly, you can expect a few bubbles in the glass. This is normal and due to the pot heating and glass refinement times being shortened, compared with large scale glassblowing equipment. It is designed to be kept in a well-ventilated garage or workshop, preferably with good air extraction. We recommend it is wheeled and lit outside, while the bench and lehr are kept indoors.
