![]() ![]() The pot time was about 15 to 20 minutes with this mix and the dry time was around 2 1/2 hours. This batch still worked how ever and I was able to get some very nice After doing this though the mix thickened and I ended up having to spoon it out. I then added in 1/2 tbs of corn starch to the mix as a hardener. I added in my paint (again 3 drops but yellow this time) and mixed until the 3 parts were consistent. You can go 1 to 2 (silicone to paint thinner) if you want a thinner mix that is pourable but its up to you. This time I used a ratio of 3/4 to 1 (silicone to paint thinner) in order to get a mix that was able to flow. I gave it an hour and a half just to be sure before I mixed up some casting silicone. This gave me about 5 to 10 minutes worth of pot time and fully set within 45 minutes. Once I had a consistent mix of paint thinner to caulk I added in about 1 tbs of corn starch as the hardening agent. I added in about 3 drops (literally drops) of paint to the mix in order to help show the details of the mould. I found that when making a mould you can use a 4 to 1 ratio of paint thinner to caulk (2 oz of caulk to 1/2 oz of paint thinner) to make a small mould using the bottom of a plastic cup. Now, reader Iceman086 has reported some successful experiments combining caulk, cornstarch and a solvent to make homebrew silicone with a pourable consistency. ![]() Our post from three weeks back about Instructables user mikey77’s “Oogoo” formulation generated some really great discussions in the comments.
