Model making session to prep for glass blowing workshop. Reflecting on materials to make a decision on which will be compatible:
Platinum 1760C
Titanium 1725C
Borosilicate glass 1650C
Kovar (copper nickel, cobalt alloy): 1450C
Steel 1205-1370C
Copper 1085C
Brass 930C
Bronze 913C
Extra Hard Solder (laser welding) 810C
Needing to avoid use of solder and create join which will withstand temps of up to 1650.
Some flexibility seen here as copper tests show no sign of melting in tests.
PREFERRED METALS TO BE SELECTED IF HOT CONNECITON MADE: TITANIUM, KOVAR OR STEEL as proof of concept with opportunity to create using platinum once concept refined post MA to elevate to to luxury status and combined with 'low' glass.
GLASS | METAL COMPATIBILITY
Platinum + soda glass
Stainless Steel + Lead Glass
Kovar + Pyrex (but graded seals)
Kovar + 8250 Borosilicate (matched seals)
Titanium + Silica glass (but check graded seal possibility)
