DESCRIPTION:In the last century the role of glass in architecture has chan
 ged: from an infill panel to a load bearing element. Toughening and lamina
 tion processes produce a stronger and more reliable material. However\, th
 e strongest glass currently available is chemically toughened which does n
 ot break safely.  An ideal toughened glass would have the high strength of
  chemically toughened glass (CTG)\, and a safe fracture pattern\, typical 
 of fully toughened glass (FTG).  \n\nAn attempt of combining these two tou
 ghening methods was performed in 1968\, but it has not been followed up si
 nce. A new glass\, toughened both chemically and thermally\, therefore cal
 led bi-toughened glass (BTG)\, has been produced. The objective of the cur
 rent research program is to determine mechanical properties of BTG\, and t
 o evaluate and model how the latter vary with different production inputs.
  This presentation will show the first stage of destructive tests\, the re
 lated analysis carried out and the possible paths to follow up to obtain a
  stronger and more reliable material.\n\n
