To support a renewed effort in Pressure-Shear Plate Impact studies with normal-impact Hugoniot and isentropic compression experiments that determine the equation of state, wave profiles, andor sound speed of soda-lime glass up to 75 GPa. The budget envisioned approximately three normal-impact experiments per year, using the 40 mm projectile gun that reaches pressures of -50 GPa for Ta impactors on soda-lime glass targets. We exceeded this goal significantly with 5 successful equation-of-state shots with partial release information on the 40 mm gun, one partly successful equation-of-state shot at higher pressure on the two-stage light gas gun, two successful thick-flyer experiments yielding temperature and shock velocity, and the first-of-its-kind thin- flyer shot on a silicate glass material, detecting both a high-precision shock temperature and a very clear rarefaction overtake.
