Yes, as plaster is brittle and may crack when under stress such as when being levered open or bolted/clamped closed.

@@stuartbray Okay thank you for answering my question!!! So I will buy burlap :)

You are so welcome!

Certainly it could

It's a good question. You'll get a better result, with neater keys and consistent controlled thickness of silicone because all that is established with clay. I really like a continuous key around the edge, and it's easier to do this in clay. Brush on moulds work well for the sort term but I like to use a pure silicone without adding thickeners or accelerators etc. if possible which can reduce library life. I have also a done brush on mould video.

@@stuartbray got ya! Thanks for replying! I’ve been studying these videos recently. I’m about to have a go at a pretty ambitious project… trial and error is my main thing… which I’m happy with (time and money currently allows)- given myself a 40% success rate on this one 😅. I can ping across what I’m working on if you’re interested (Paramedic… making a training aid)

If you are using a mould then you'll need a material which starts out as a liquid and then dries or cures to a flexible solid. There are a number of materials that have this property but latex and silicone are the most reliable and easily acquired. There are also flexible urethanes but these are smelly and unpleasant to use for masks. There are liquid neoprenes too but these are not easily found in the UK so I haven't used them

J. HERBIN grade 50. They make about 5 softnesses

It's available in different thickness, or weights. Usually the one I use is 600g which is the weight of a square Metre. That I use two layers with a third on any flange or edges which need drilling/bolting/clamping or levering against.

Thanks, Gina. I really enjoyed making this video too.

About 2kg

I would never advise straws in the nose, as knocking that and carving a groove into the nasal cavity isn't great. It also distorts the nose and lays flat over the lips and gets in the way of business. I 3D scan nowadays instead life cast in the main. So much more accurate and comfortable.

@@BattlesWithBitsofRubber no computer in my day. No videos in my day. And no books just pamphlets with silly drawings on them so I learned the hard way with all the other oldys but knowledge was handed down and nice to see we where able to hand it over to the more advanced technology of today. But I see your point with the nostrils but still think it's a great idea to use skin safe on the human skin and pop a straw in the mouth if you choose the old fashioned way of the old school mould maker.

Naturally you'd use a skin safe silicone for life casting. This video is about making a master mould from a plaster, so this video isn't about skin safe materials. I have done life casting videos where this is the subject. I too grew up learning from old school techniques and masters. It amazing actually how much you appreciate the new tech having spent 30 years never having it. I worry that mould makers who only use digital won't have the hands one experience to appreciate the benefits of being able to print up moulds and mould jackets. There's nothing like hands on experience.

@@BattlesWithBitsofRubber I'm sorry if I come across telling you how to make a mould that's not my intention im saying this for new mould makers watching your video. I seen some on on you tube make a two part plaster mould of some ones hand then try to open it with a Stanley knife on the person's hand. I also seen a guy taking a fibreglass mould half from another man's torso and struggling for a while you heard him taring it of. I could not believe it. So it's just in case some one gets ideas from your video. It's obvious to you and me but not to others

@@michaelpearson1272 yow! That madness. You seen the lifecast video of a woman who has her head thru a hole in the table and a box built around it? They filled the box with alginate and it pushed away the straw up her nose and basically she started to panic and nearly drowned. Gave me the heebee jeebees.

You can try. I haven't used gelatine for years now but only way to be sure is make a small batch to test and see if it will do what you need.

Hey! Thanks for the support. If you want silicone pieces with cap plastic encapsulant, then I would indeed do that. Personally though, I woukd make them in a flat mould but use a Prosaide Based paste such Bondo, Prosthetics Transfer Material (PTM by Tinsley is fantastic) or similar. That doesn't need a cutting edge doing as there is no cap plastic involved.

Thank you for responding so quickly. Appreciate :) @@stuartbray

yes, I'm using silicon pieces cap plastic encapsulant. regret doing so many veins in one small area :( taking longer than I thought to do cutting edges :(

All cap plastics should dissolve with acetone, even the alcohol based stuff. Sounds like the edges are not pure cap plastic, there is some silicone in between the two layers. This means the thick edge you are trying to dissolve is not cap at all, but the silicone between the layers. Nothing dissolves silicone, and a thick edge like that means something went awry in the casting stage.

@@stuartbray thanks. I tried some other piece I made and they dissolved. I bumbed that particular one up 🤣🤣🤣

From a special effects materials supplier. It all depends on your location as to which supplier is closest. Whereabouts in the world are you based?

I don't rate Glatzan as an encapsulant, but ifbyiuvare going to use it then thin it as much as needed tobget through your airbrush. Usually around 6 or 7 parts solvent to one part cap plastic.

@@stuartbray thanks for the answer I'm a beginner so I don't have airbrush yet trying to make it with a simple brush , also do you think glatzan is a bad choice to begin with for encapsulating pieces ? thanks again for your time

@TheEdvinas694 yes. I don't think nit is very good as an encapsulant. I found it too stiff, so I'd recommend Baldies acetone based cap plastic. It can also be bought as a pure dry plastic bead, which makes it easier to ship around the world

Cool.
