Glaswerk Ernstthal GmbH's mission statement

In the year 1703, Duke Johann Ernst granted Ernstthal the right to produce glass. In line with this tradition, the glass works was founded in 1923, in the heart of the Thuringian Forest. Therefore, we are proud that we have managed to grow the size of our company as well as our range of products to a new level since the 1990s, thanks to continuously high investment and the development and use of modern machinery and plant technology.


Meanwhile, we are the largest industrial employer in the Sonneberg district.

We melt up to 600 tons of glass daily. From this, we produce 1.2 m bottles for spirits, dressings and oils as well as exclusive designer bottles.

Our strengths include fast, customer focused product development and flexibility of our batch sizes. This makes production of smaller customer orders possible. Thanks to this and to individual design and colouring, we significantly improve the recognition value and value chain of our customers.

We implement several hundred new glass bottles annually that are represented in our range of products.

We translate our customers' ideas and requests flexibly, creatively and quickly. We carefully prepare the introduction of new glass packaging, from the first draft to the technical drawing of the article in three-dimensional representation to a plastic or Perspex model.

Production

Raw materials

Container glass is created from the following raw materials, that are mainly natural resources:
· Silica sand
· Dolomite
· Limestone
· Feldspar
· Soda
· Small components
· Recycled glass
The exact composition of these raw materials (the "recipe") is called a batch in the glass industry.

Melt

prod_schmelze1.jpg

The batch is transported into the melting tank via an insertion machine. Here, the crystalline raw materials are transformed into glass at temperatures of approx 1,600 °C in the upper furnace. These temperatures are generated by natural gas flames that sweep over the glass bath and heat it up to more than 1,300 °C towards the bottom of the tank.

Top ...


Forming

The premould is the basis for optimal distribution of the glass through an article-specific forming of the moulding tooling and the mouth.

In the final mould, the article is blown up to its desired volume, using compressed air.

Cooling processes

The still glowing bottles then cool off in so-called annealing lehrs. This process takes up to 90 minutes and prevents stresses within the glass.

Surface finishing provides for additional protection of the glass bottles.

Top ...


Quality controls

Computerised controls guarantee the high quality standard of the glass containers during the entire production process. This continuous product control ensures that faulty containers are detected and sorted out.

Top ...


Packaging

A fully-automated, flexible packing technology permits packaging in different sizes and pallet formats. As per customer request, various means of packaging are used.


Storage

The finished bottles are stored in our logistics centre in Herrnberg. Six warehouses with a storage area of more than 36,000 m² allow for loading of 60 to 70 lorries daily. The bottles start their journey into the whole world by lorry or container from this site.
