As everyone has said this is a great and descriptive video. Thanks alot for the help. I do have a question when i run foam the volume increases about as much as yours but I cant pour it like you do its way more viscous any tips? From reading the comments an update/faq video would be greatly appreciated by alot of people me included Thanks so much
The reason you seal the clay is because the ultracal will leach moisture out of the clay if not sealed and make a weak mold right where you need it to be strong . It should not be optional if you want a good mold . Any kryolon gloss will work fine
Hi i know this vid is quite a few years old now but hoping you can give some recommendations... I'm having a really hard time with the smell, is there anything I can apply to the foam latex to eliminate or at least minimize it? Thank you in advance!
Hi Samantha. The smell comes from both the ammonia used to maintain a liquid state and the sulfur needed for the foam to cure. For a while I used to add some vanilla essence to my foam to mitigate the smell… but the price rise made that cost prohibitive for me. If you can afford it it works well
Well, there is a very good reason why ALL latex mask makers use Hydrocal , Pottery Plaster, or Plaster of Paris . Ultracal should only be used when you need to bake the mold or put a large a mount of pressure on it. Ultracal and other white Gypsum plasters , absorb the water in the latex and build up a nice thickness in one pour. Let's not try to reinvent the wheel, when we already know what works best for which purpose.
ultracal 30 is pretty decent for long lasting molds. Ive been using it for many years. The molds last longer than pottery plaster or plaster of paris by almost 100 or more pulls. I didn't really like hydrocal because after a few pulls it gets more and more porous than before. Using heat above 100 F to 200 F will cause ultracal to crack or explode depending on how high the temp is because of its low shrink value. Sucks to have to vacuum your oven.
Yes, you are correct. Hydrocal is superior for its capillary action in regards to leeching out the ammonia and leaving a nice even skin on the mold. It is not, however, superior in terms of strength and library life. UC30 lasts a whole lot longer, you just need to leave it to dwell for longer and you will still get the same effect. When I worked at Universal we used to mix 2:1 UC to HC to try and wlk the line between both worlds. It worked pretty well. This mold needs to last for many many pulls, so I decided on UC30. I am not "reinventing the wheel". Many people use Ultracal 30 for mask molds. In fact, Rick Baker recently had Rob Freitas mold one of his mask molds and he used Ultyracal 30. Be careful throwing around words like "ALL" and "ALWAYS".
@@toxicimagestudios9547 what do I know, I've only been a special effects makeup artist for 40 years. I have hydrocal molds that are 30 years old . Now I use number one pottery plaster for all latex items .
@@toxicimagestudios9547 you talk about using an air gun to get the bubbles out of the UltraCal in the video. Could I use a heat gun instead or would that be too hot for the UltraCal?
I don’t think you would get the benefit with a heat gun. The air pressure is usually too l,ow and you risk more causing issues to your sculpt, especially if it is an oil based clay. Heat gun is the wrong tool. You’re better off just blowing on it
Ok....I have looked up the "Easy Release 200" Some are yellow cans with black text and others are black cans with yellow text on it....are these the same thing but just and updated design on the can? I would figure it would be the same but you never know with this stuff.
I never have, but I am also sure I have killed some of the few active brain cells I had left with the ammonia fumes. I dont know anyone who wears a respirator to run foam, but if you feel more comfortable doing it then do what makes you feel better
It depends on how thick you want the mold walls, really and what you'll be doing with it. It also depends on the size of the sculpture. Too hard to answer without those specifics.
very neat work, honestly. not just the actual application but the way you display it and explain it, very informative very much baby steps, and cam is spot on on the proccess. thanks for the effort. like and sub.
if you are referring to a hand turned egg mixer then no, that would not work. You wont get enough speed to get the rise you want and you wont be able to maintain an even speed whilst refining to avoid bubbles. You should use an electric mixer for sure.
depends on which speed of Ultracal you are using. If it is Ultracal30 then it should take 30 minutes if mixed according to manufacturers specifications. A good rule of thumb, though , is to go by the temperature of the material. If mixed effectively, it should heat up considerably as it sets. Once cooled you should be able to do whatever you need to it. If running foam latex, however, you will most likely need to bake out the mold to remove the unwanted moisture or you can get delamination.
I'm actually getting started with all of this but I couldn't find a video for foam latex prosthetics until now. Thank you for posting this! also, does it matter the kind of oven used for baking the prosthetic? because i have a gas oven and I don't know if that would work.
I did use acetone to clean the mold after removing the clay. My first mask pull was having little brown stain all pver the surface. Should i pour more mask or try to clean with alcool 70 or 99 pourcent? Don't know if its because of the acetone the reaction
The reason I l Ike WED is because it is very soft. If you use a hard clay then it can jack up your sculpt (if you are molding a sculpt). If you are molding something hard then you could absolutely use plastalina but it will be a pain to work with and finish down. You don’t need any detail and water clay is easy to clean out of the jacket. You can throw it fast also. If all you have is plastalina then you could in theory use it., but I think it would be better to get some water clay.
Thank you so much for your tutorials. Its so helpfull. But my problem is, im just have an latex liquid. Did any ways/chemicals to make my latex foaming and cured. Because in my country hard to buy latex foamer.
