Think I've used this. It needs a really slow cure resin. Fast ones release too much heat and remelt the material. Or use plaster

I used medical alginate used by dentists to make molds of teeth.

Yeah, I used it a bunch of times at University in the sculpture lab. We would get "expired" dental supply. (half full 30 gallon drums usually) mint flavored lol

Ask your dentist if they have "expired" gel alginate.

University scultpure lab used to get it mint flavored all the time. No heat involved. No danger, no risk. made of algae. So safe you can cast the inside of a mouth...

I don't think I've ever put anything in the microwave for 5 minutes.

I remember the meat spin site, but apparently, this isnt it. Nor is it anything, cuz it doesn't load.

It's worth noting that like many compostable things, gelatin stinks to high heaven when it's rotting. Put that shit in the center of your pile.

It stinks to high heaven while cooking too. Used some for a baking evil and my whole kitchen smelled like a barn for a week.

Dang, 130 degrees? So much for a clone-a-willy kit 😂

It should still be viscous enough after cooling below 110°F to do that and by that temperature, it'll be safe for a few minutes.

I mean...130 degrees Fahrenheit is just Arizona summer

Different method, yet similar easy method to create molding material

The cornstarch method is always f***** up really bad for me. I have much better luck with blue Dawn. Basically you're making a mix of about 5 to 10% blue Dawn 90 to 95% water getting your hands nice and soapy and then squirting the silicone into the mix and then working it around with your hands until it's consistency changes to a solid homogeneous Mass. It is wet, so you will occasionally get small pockets in it but you can take it out of the water and kind of fold and squeeze it to reduce that

That caulk is not body safe, before anyone gets ideas.

2 weeks ago | Likes 19 Dislikes 0

Well yes and no. There are multiple types of silicone caulk, definitely those types that employ petrochemicals to speed curing should not be breathed or have contact with skin. But pure acetoxy silicone products really only generate acetic acid, AKA vinegar, as they cure. They can cause skin redness and irritation, especially for doing a lot of work. I get a little bit of redness and dryness in my hands after doing 5 or 10 pieces, but the amount of contact necessary for a single molding, would

Do nothing to my hands. I can't say that I've tried it on other body parts for that I would 100% recommend it but I don't think it would end in a *total* disaster. I think the key thing would be your er, mold release. That's what it's going to protect your skin from the vinegar. The curing agent I use for silicone is dishwashing soap anyway, I would just have to use the higher concentration I think

So if you already rub your junk with vinegar and blue Dawn then you doing everything to it already that would be done by a silicone mold as long as you're getting the 100% silicone acetic acid cure only clear no additive colorants etc stuff

Interesting, I used caulk for something like this a while back, and all the products I found had anti-mold chemicals in them and apparently those are very bad for you before it cures completely.

A lot of standard silicone caulk does not have any kind of antifungal agents, although all types made for bathroom use do.

2 weeks ago | Likes 6 Dislikes 0

Yup, that's the only kind I could find.

I believe what we buy is crl from Richelieu as it's the cheapest but I've only had one kind with a hardening agent (aluminum?) & it sucked for tooling!! But I use it for commercial millwork install & caulking. Never thought to try & use it for anything else because it's stupid & gross 🤣 We put our hands info the beltsander powder to clean silicone off before it gets everywhere!! You all are crazy

Does it harm the cylinder? It's very important that the cylinder remains unharmed.

Simply use tongs and place the cylinder in the mold so your fingers aren't burnt.

The cylinder is attached to a larger object and cannot be easily moved.

It will slow-cook the cylinder.

I don't think the cylinder will survive the 130F temperature he mentioned.

If you want to try it on your cylinder then I'm not gonna stop you.

It's all about the duration. For a quick dip? Probably not, but for prolonged exposure (you have to keep the cylinder submerged until the gelatin sets), that is enough to cause burns.

2 weeks ago | Likes 17 Dislikes 0

aren't there other problems with the cylinder holding it's shape for so long? some cylinders go slack if left alone too long i find

2 weeks ago | Likes 13 Dislikes 1

There are tools for that, I've been told that they can help greatly.

That's what the tourniquet is for (that is absolutely not what they are for, do not tie a tourniquet around your cylinder)
