Thermal shock constitutes the primary obstacle in combining ceramic and glass. This barrier is overcome via the empirical verification of errors in each edition, with the aim of reducing fractures to a minimum.
But from these ‘errors’ another beauty and form emerged: the idea of creating a series of objects illustrating the evolution and variations of precisely what happens ‘in between’ the process from ideation to final piece. This project has been developed closely with ceramic and blown glass artisans from Argentina at the factory Cristaleria San Carlos.
A detailed look at the process reveals Heidi’s care. First, the ceramic pieces are hand thrown. Once they are in a leather state, they are cut to leave a gap that the glass re-composes in the next stage. After the ceramic is dried, the pieces enter the kiln at 950º. This low-temperature cooking allows the pieces to bear the thermal shock, contracting and expanding as the melted glass fits inside. To complete the glass segment, the ceramic pieces are reheated to about 300º. The blower then fills the inside piece, and the two shapes become one as they are attached together by form.
This project was exhibited and awarded in the second edition of the “Open To Art” bianual international competition, which is dedicated to ceramic art and design. this competition is developed and promoted by Officine Saffi (Milan, Italia)
Prize awarded in the art section: a Solo Show Prize, Museo del Design 1880-1980 – Milán, Italia.
