Finally got some plaster now I won't have the fear of the sculpts getting messed up in any way I feel better once it's molded lol

Just curious, how does the price of the plaster compare to shell shock? And how is the durability? I am thinking of trying plaster for my next tail since shell shock is pretty expensive, but I am worried about the moulds cracking or shrinking.
Personally I've never tried shell shock cause I get this plaster at my local hobby lobby store but this is net weight 8 pounds for $7.99, I wouldn't use anything else for now just because the clay comes out in one perfect piece no having to dig it out no cleaning the mold a thousand times it just peels of and none of my molds have broken yet I don't handle them like a glass doll I mean I don't throw them either but there's been a few times where I thought they were or should have been broken and held up with no cracks, also I mix a little extra plaster to make the end result stiffer. Let's see how the hold up when I move if there are no casualties I'll stick with it. Hope that helps!
And speaking of molds i maniged to finish my last fins now all that's left is dorsal scales and fluke.https://uploads.tapatalk-cdn.com/201...07341b164d.jpg

How much does one 8lb bag make? Do you think that would be enough for one fluke and a scale tray? That is significantly cheaper than shell shock, haha. Also, have you used any silicone in it yet? I think I remember one mer having trouble with silicone seeping into her plaster moulds and permanently bonding to it because it was too porous. It was years ago though, and I doubt its the same plaster. Just curious if you had tested that yet.
No i have not tested it with the silicone yet. An it took one bag to mold almost all my fins and the molds are pretty thick.https://uploads.tapatalk-cdn.com/201...f359ba5130.jpg

This was my least favorite part of the process by far, I hated working with plaster how are yours so clean...clay free

To be honest Lili I don't know why they're so clean I've never had to clean then after molding cause the sculpture always peeled right off the mold I have a video on it above that's another reason I've continued use of this plaster.Quote:

So you think one bag would be enough for a fluke?

When I make the mold of the fluke in a couple weeks I'll let you know how much I used.
But keep in mind my fluke is for my extended tail so it's especially thick so if your making a fluke for a regular tail that is not very thick one bag should be sufficient, just be sure to make the clay walls at least one inch from the sculpt all around so your not wasting much plaster in empty space!

The thicker you make the molds the better they will be for holding up over time and not cracking.
when it comes to Quantity it can be hard to determine. I used 2x 4KG bags on one of my flukes. Keep in mind the thicker the mold the more you will need.
when dealing with a large area it is best to mix up two buckets. (helper) and pour at the same time. its impossible to mix and pour such a large area in the time you pour your first batch, even if you have the plaster and the water already measured out and ready to go. speaking from experience.
Thanks for your input Trident True, I've been researching a method for making silicone harder I've found a few ways but I can't say for sure until I have tested these theories...

You cpuld just order a harder shore of silicone to make it harder. I dont know of a method that doesnt weaken the silicone and expose it to potential crumbling.
The hardest A shore of dragon skin is A 30 and that's way too flexible with the method I found it becomes closer to a A 70 I've seen it done it did not crumble I don't know how it would any ways.

Well I wish you luck then :) Ive only seen two attempt a method like that. On one the silicone got very hard and began crumbling when it was flexed. It was like old dried out rubber. The other attempt was unsuccessful and the silicone just wouldnt cure. I would be interested to see if you are able to get it to work. :)
Can I ask why you want the silicone harder?
Good to know thanks Rett! The reason I want it harder is only for the fluke I'm going to use lexan for my extension piece/monofin and the lexan available at home depot is one size thinner than what I'd prefer being that the thinner the lexan the more bend it'll have which is not what I'm going for I honestly dislike flowy or bendy flukes at least if the tail is for myself also I feel it's better to have a fluke that can provide effective propulsion in ocean and river currents which is what I mostly swim in, a flexible fluke provides less propulsion...Quote:

Ah, gotcha. Well I hope you are able to figure it out. Maybe you could try a different material for the blade? Fiberglass (like the Finis Competitor) perhaps?Quote:

Little tip! I learned that legos can be used to create mold walls all one needs is tape to hold the legos in place. It's brilliant!

Unfortunately I don't have the technology to make a functional fiberglass blade like that it's not a simple thing at all! But I've figured out how to make the silicone harder all is left to do is try it and see how it goes for me but I'm sure it'll work and if it does uff i wouldn't even need a monofin for any of my tails...Quote:
