In 1899 at the invitation of painter Julian Fałat, Laszczka settled in Kraków where he became the professor at the Academy of Fine Arts. Most of his works were inspired mosty by personalities observed In his everyday life, but also by mythological and religious busts and caricatures.

He died in 1956. In small town Dobre the school was named by the name of Konstanty Laszczka and the museum of his works was founded there.

Fly ash, resulting from the combustion of biomass, alternative to natural feldspars
The study evaluated the possibility of using fly ash from the combustion of biomass in the production of sintered ceramic materials. Presented a qualitative evaluation of these waste materials, including the ability to apply them in a place popularly used feldspars in ceramic masses. The evaluation of the quantity of the fly ash fed to the raw material was done in the context of the ability to fulfi ll the quality requirements of the industry. The study was based on the microstructural analysis, the measurement of the apparent density, open porosity and water absorption.

Folk and Artistic Industry Cooperative "Kwiatogal" – beginings, production and style
The article covers the topic of a fairly forgotten Folk and Artistic Industry Cooperative "Kwiatogal". The cooperative was established in 1950 in Warsaw and initially it specialized in artificial flowers production. In 1951 it opened porcelain paint shop and this part of its activity – hand painted porcelain – is the main subject of this article. The author explains the style of the Kwiatogal's pieces of porcelain, the approval process for new designs and the diffi culties the painters faced at decorating porcelain sets. The author also tries to characterize the designs created at Kwiatogal's paint shop giving the highest value to geometric and fi gurative designs falling into the global design trend called "New Look". She also mentions the names of ceramic artists: Danuta Duszniak and Stanisław Tworzydło exercising artistic supervision over the cooperative's production.

High temperature resistant ceramic crucibles for transparent ceramics fabrication
In the presented paper fabrication method of ceramic crucibles for special application (sintering of advanced ceramics) is presented. Crucibles were moulded in plaster moulds from ceramic slips. Suspensions of ceramic particles, used for moulding, were characterized in terms of their rheological properties. These properties were quantifi ed by means of Bingham model (in plastic region) and Power law parameters (in shear rate region, where viscous response for applied shear appeared).
