In the first article in this series, I discussed why glass casters should build a parts library of mastermolds. In this article (part II), I’ll talk about the easiest of mastermold-making techniques: The plaster mold.
Silicones, urethanes, and resins–the stuff I make most of my glass casting mastermolds from–can be spendy and hard to find. The moldmaking techniques they require can be time-consuming, with a steepish learning curve.
So don’t use them when you start out; use plaster of paris, or inexpensive bisqueware, instead. There are a lot of advantages to making mastermolds with plaster of paris:
It’s readily available in […]
A silicone master mold is an obvious safety net in glass casting: If you accidentally employ one of the 10,000 methods for destroying a piece during casting, a master model gives you a second chance.
That’s not all, though. As tedious, time-consuming, expensive and messy as they are to create, master molds are probably the single best investment a glass sculptor can make.

Bob-the-blowdryer died a fiery death on Wednesday. I laid him to rest (in the trash can) and… mourned. Slightly.
Maybe I should explain.
What do the above pieces have in common? They still live with me.
I’ve never really thought of myself as sentimentalist. Sure, I sometimes sob at tearjerker chickflicks or cracking good animation or sublimely elegant algorithms or wonderful UX or hardware that really IS “plug and play” or somebody just being nice for no good reason or incredible art. And maybe I succumb to leaky optics over certain scents or songs or baby animals but…
“The recommended amount of air leakage for your home is 2,060 CFM50. The actual amount of air leakage tested to be 6093 CFM50. The results of this test show your home is 196% above the recommended level of air leakage. This classifies your home as Very Leaky and puts air leakage reduction as a high priority for energy savings and air quality improvement.”
I am very leaky. Or rather, my house is.
Not a huge surprise, since Jesse-the-greenguy turned my upstairs hallway into a wind tunnel simply by closing the windows and sticking a huge fan in my front door, blowing out. Air sucked in through all the leaky windows and literally whoooooshed my hair into an updo as I stood there. […]
Stopped off at Home Depot to pick up a couple of things, waited patiently in line to pay for my purchases.
And no, that’s not the line I’m talking about.
While I waited, I daydreamed about the new Sapphire Rose lead crystal billets* waiting on my doorstep (yum). That occupied me all the way up to the counter, where the credit card reader gave me the third degree:
