How-To:  Make cheap castable silicone from caulk

How-To: Make cheap castable silicone from caulk

Turns out, though, that mixing in some cornstarch accelerates the drying process; just how much depends on how much starch you add. The author recommends starting with a 1:1 mix. I’m not sure about his explanation that the process works because the hygroscopic starch carries moisture into the internal volume of the silicone, but in any case there are probably other additives that will accelerate the process as well as or better than cornstarch. You might even find one that’s not opaque and allows for translucent castings.

How-To:  Anodized titanium jump rings

How-To: Anodized titanium jump rings

Titanium is really cool for a lot of reasons, but this Instructable by, ah, “Thursday” highlights one in particular: It is incredibly easy to anodize, and produces really striking colors when anodized. So, you know, if you’re interested in anodizing this is an way to start experimenting. Thursday has stripped the anodizing process down to it’s absolute minimum here: small titanium bits, white vinegar, a stack of 9V batteries, and a counterelectrode. Now I want to see somebody use all those differently-colored rings to make a chain-mail photomosaic.
