Hey guys!
So heres an update on my milliput/GS experiments. hope it may be useful to some of you

NB: by milliput I mean the white, 'superfine' one. i dunno about the other varieties (terracotta, yellow etc).
So overall, I think milli isnt best used for casting pieces in general, but it has some qualities which make it awesome for a certain kind of texture: it gives sharper results, it's more solid, and the texture is less 'round' or 'pasty' than GS…
@Crowsfoot if your experience is different please say so, i'm a beginner here.
Main drawbacks:
- Milliput, when it cures, has a tendency to "absorb" liquids, including oil. Which means it sticks to the mould (when I took off the parts, the moulds were way dryer than with green stuff)
- it becomes rigid and fragile (GS remains more flexible), which means if you pull one part of the piece too hard it may snap off (unless maybe you use a thick layer, which is less cost efficient).
- so little, simple bits will probably work because when you remove em the pull will be more uniform, while bigger bits have to be removed little by little by progressively levering each side with the knife. On the bigger bit (pic below) the parts i pulled, being pretty thin, broke apart from the main piece.
==> So to me, GS seems better suited if you need to cast bigger, more complex bits: even thin layers will withstand a harder pull.
I may be wrong though, i'll be making more experiments…
- Maybe more oil would do?
- Maybe i just used too thin a layer or pulled too hard…
- Maybe if i had removed it before it cured entirely it would have been ok.
- I havent had the time to try using the bits, maybe milliput will be easier to file, being more solid, so itd provide a better result on the model…
- Also, with more flexible moulds (oyumaru…), i guess you could push the mould from underneath and not pull the milli. I'll probably give it a try
What the features of milliput, as compared with GS, seem to allow:
- it's more solid, so maybe edges etc can come out sharper (they often seem a little rounded with GS), and the texture feels more 'stone-like', 'bone-like'…
- it has a tendency to crumble while GS has a tendency to get 'ripped' or 'torn' apart. It feels more like plaster… The 'crumbling' aspect allows for awesome ruin effects. If you mould or sculpt a piece and start taking bits off you'll have a nice "damaged" effect: here's an example, look at that piece on the right. i failed to take it off the mould in one piece but now it looks pretty good i think…
So yeah, don't hesitate to tell me what you think and also, please let me know if you're interested or not in more postings on moulding/casting, I'm getting very excited and interested but you guys may find it boring
Anyway, heres a pic of the pieces i cast! GS stuff is still not perfect but it's a good start. The milli parts i did pull off are good too

More to come over the next few days. of course comments, thoughts, criticisms, ideas suggestions (…) are more than welcome
