In particular, he used two electrodes to select the biscuit; the passage of electricity through the material showed that it was not suitable for the successive glazing.

The production chain for ceramic tiles was then mainly handcrafted and labour-intensive, but Leo Morandi's inventions started the successful automation of various units. After the initial years he was able to open a distinct efficient production unit. Morandi was a reserved man and did not like publicity. He involved his workers and customers in the improvement of his inventions and innovations.

Ceramic industry equipment examples include: automated floor tile edge glaze remover, automated packaging (floor tiles where historically bound with thin iron wire, before shipment), specialized silk screen machines, the peristaltic pump, the transport line, the hydraulic press, tile overturning mechanism, press reception unit, and glazing applications done with disk booths. These basic tile processing elements are still in use.

Leo Morandi began exporting these proven automated Italian ceramic industry innovations to Spain, allowing advancement of two primary ceramic industry clusters.
