Silicone Mask Silicone?

So I have created a negative of a sculpt (two part plaster) for a full head and top of shoulders mask; I would like to cast it out of silicone but I am not sure what to use... I need something available in uk that can stretch a lot (it is a tight mask so that it binds to your expressions) and is soft like skin. (And Cheap! :) tops around £30) I was thinking about platsil Gel 00 or 10. What do you think? Thanks! (And if you can, how much would I need?)

silicone stuff

Long time listener. First time caller. Excited to be on your show guys. What I would like to do is make my own silicone bracelets / bands. Like Lance the liar Livestrong bands. But cooler. I've seen lots of posts on creating silicone molds. I think I can figure that part out. What I haven't found is a discussion on molding stretchy, rubbery silicone stuff. In my case - wrist bands.  Anyone here have an idea on what to use and how/where to purchase? I chatted with the kids at Make Your Own Molds and they were helpful on making my mold. But they couldn't recommend a site to buy the silicone for the bands. Help!!

Attach membrame to silicon housing

Burning question! I am trying to attach a membrame (which is made of latex at the moment) to a silicon housing (see attachment). The membrame should be a able to move vertically and thus expand a bit. The two challenges are: - The membrame should not be to thin, because otherwise it snaps and; - The membrame should not be to thick, because otherwise their is too much pressier on the sides and it also snaps. The membrame and the silicon housing should be airtied. The material of the membrame can change, although it needs to be flexible of course. Any tips on which material to use for the membrame or on assembly techniques? Cheers, Thijs

Casting pewter in RTV Silicone

I want to reproduce a bit of jewellery I have designed in pewter by using a 2-part RTV silicone mould. By all accounts it is possible but I've run into some problems when sourcing materials. Most high temperature silicones I have come across state a maximum temperature of 250°C, But pewter has a melting point of around 280°C. My feeling is that the mould itself will most likely never actually reach 280°C and will probably only be above 250°C for a short period of time. But I'm wondering if anyone has actually done this and could verify for me. Also as I'm new to the whole process, any other tips are welcomed. This is the high temp silicone I'm currently looking at. Thanks,                -Tom

how could i bound polyurethane and silicone ?

Hi I'm trying to make a two part model in polyurethane resin with a thin silicone membrane connecting them so it can expend  and still be maintained by the silicone layer. The problem is that i need to pour the silicone into the model, so i can't make them stick together with some coating or glue. Instead of the silicone i thought about using polyurethane elastomer but it is usually not very elastic and does not age well when frequently teared neither. So i'm searching for a way to pour silicone into polyurethan resin and make it stick. Maybe eventually by putting some fiber on the resin surface while wet so it'll get trapped in the silicone layer while it will catalyze but i doubt it'll resist to the tear strengh for a long term use. Did any of you tried it or found a solution to that problem ?

Is oogoo (DIY Silicone Putty) Oven-safe?

Hello! I have a question for people who use oogoo, or generally DIY silicone molding putty made from 100% silicone caulk. I want to cast oogoo molds of lego bionicle masks with polymer clay, but my issue is I need to keep the clay inside the mold in order to prevent any kind of warping, as most of it is spread a little thin (1-2mm thickness) and I don't want to end up warping it even in the slightest. Is oogoo or cured 100% silicone caulk oven-safe as long as it's within the specified temperature range? (I already know most DIY silicone putties aren't food-grade.) The silicone caulk I'm using is GE all purpose silicone I, mixed with corn starch, acrylic paint, and baby oil. The back of the tube says that it should not be used on surfaces that will exceed 400F/205C. The polymer clay I plan on using is cured at 110C, so I don't think it'll be a problem, but I'm worried exposing the silicone caulk mold to high temperatures will cause it to release some harmful chemical compounds. I looked up an MSDS sheet for GE silicone, and they had a generalized one stating exceeding the maximum temperature will cause the release of formaldehyde. Since I plan on baking these in our kitchen oven, I wouldn't want harmful chemicals contaminating a space where we cook our food. Also, if baking isn't an option, since the polymer clay is spread thin, and cures close to 100C, would curing it in boiling water be an option? (That way any water soluble chemicals would remain contained while the clay hardens.) All help is appreciated!

Need easy-to-find alternatives to food-grade silicone, to make molds. Would aquarium silicone do?? Answered

Hi. I would really like to make some food-grade molds (candy molds). I know that food-grade silicone is the way to go, but here in Norway, it is not that easy to come by, and when you do, it's very expensive. My question is whether there are viable alternatives, that lasts. (not a make one, and break it thingy..) I know that aquarium silicone is supposed to be non-poisonous, but will it do as a mold material? Or are there other alternatives I can make myself? or buy at a hardware store.. I know there are a lot of silicone products out there.. Surely some of them would be safe to use in food prep? Thanks for all answers. Best regards, Klaus, Norway.
