• I assumed the mould goes in the vacuum chamber as well so the bubbles are sucked out after the pour while in situ?
    I know nothing of silicone but have seen something similar for resin pouring in wood turning vids where a vessel is filled with resin and wood then the whole thing put into a vacuum chamber but maybe the process is different for silicone.

    In other news, I got a introductory glass blowing lesson for Xmas from my partner, so freaking cool, can’t wait.

  • yes, thats my understanding of how it works with wood/resin

    glassblowing lesson sounds great, you'll have to show us the results

  • Well I fuck around with glass anyway so seemed like the next obvious step as although my current skills would lend themselves to stained glass work I’m just not that into it.

    Blown glass should be fun, I think I get to make marbles, a paperweight and a vessel of some kind on my taster day.
