“The history of the production of one particular glass factory is recorded in a series of objects under a unified name – Recovered.”


The main idea of the collection is to give the glass process waste a new shape and meaning, and above all to preserve its unique aesthetic qualities, which have become the main sources of inspiration. The aesthetics of glass destroyed deliberately and in

a controlled manner is evident on every object in the Recovered and Recovered.history series, although the processing techniques and forms are strikingly different. The colour scheme of individual objects reflects the history of glass production of one particular glassmaking studio. The collection consists of three series, each representing a particular type and treatment of waste, and aims to interpret the viewer’s unique aesthetic experience with a little exaggeration.

1) Standard glass waste, shards

During normal production, process waste consisting of shards of different sizes is produced even in a small glassmaking studio. Pure crystal shards are separated from this amount, which can be remelted. However, a relatively large amount consists of stained glass, or is simply too contaminated, and usually ends up in a waste container, where it accumulates every day, creating layers reflecting the production of that day. This has become the main inspiration for new glass products.

 Glass waste shards are taken back again. However, there is no sorting or division on our part. We reclaim the layers of accumulated waste and transform them into products that reflect the aesthetics and at the same time provide a kind of documentation of the production history. Functional objects thus reflect the record of the development of current production over time as, for example, the colour changes. Based on the size of the shards, it is also possible to estimate in retrospect whether thick or thin products were produced in that period. 

 In this case, we leave the form, as well as the colour scheme, more to chance. This creates unique objects that can never be repeated. Each product is marked with a serial number and month and year of manufacture.


2) Unused, strongly stained glass

The so-called “rubies” are used in handwork for colouring and decoration of glass products. It is a strongly coloured stained glass in the form of cylinders, which are used in various production techniques by heating. However, not all of the material is used for processing, and

a considerable number of unused pieces is produced in the glassworks within a few years. This residual material is gradually mixed and

a simple tool is used to melt several colours together. Due to the different hardness of the individual colours and their chemical reaction,

a unique decoration material is created when mixed. This material is placed on the classic crystal glass shapes that are typical for the region where the glassworks resides.
