Mirror production for the Cherenkov telescopes of the ASTRI mini-array and the MST project for the Cherenkov Telescope Array

The Cherenkov Telescope Array (CTA) is the next ground-based $\gamma$-ray observatory in TeV spectral region operating with Imaging Atmospheric Technique. It based on almost 70 telescopes of different class diameters - LST, MST and SST 23, 12, 4 m, respectively to be installed two sites hemispheres (at La Palma, Canary Islands, near Paranal, Chile). Several thousands reflecting mirror tiles larger than 1 m$^2$ will produced for realizing segmented primary mirrors a so large number telescopes. Almost parallel, ASTRI Mini-Array (MA) being implemented Tenerife (Canary Islands), composed nine m diameter dual-mirror (very similar SSTs). We completed production all MA (400 segments total) using cold glass slumping replication technology. results related quality achieved large-scale are presented, also discussing adopted testing methods approaches. They very useful adoption optimization assurance process huge (almost 3000 surface) CTA
