Just lately I was trying to sculpt miniatures with all the sculpting clays I had in my box
, one with each material, and this are my impressions;, from worst to best;
Patcolor/air drying clay; it is good that it shrinks, about 20 %, hence you can sculpt bigger, but dries very quickly and is usually too soft.
Cernit; very unrecommended, sort of rubbery and doesnt retain properly shapes.
PREMO; Again, too soft, even worse than Sculpey.
Sculpey firm; not really very recommendable, because even if it allows me as much time as I wish to sculpt it, as is a baking polymer clay, is too soft really.
Aves Apoxie Sculpt; it is acceptable, but tends to be rather soft and unfirm. Of course, altering the proportions, letting it dry a little bit, even placing it on the fridge for a while can improve, but is really not very convenient.
Aves Apoxie Fix it; better, more solid, but very expensive really. More or less the same than the previous, but slightly better in all aspects.
Pro-Create; quite good, is again a two part putty, but with slightly rubbery properties. Quite firm, you can imprint well the details.
GreenStuff; finally, for me, the winner. IT might be as extra that mine has become dry and old until it's nearly unmixable, but at this stage, is tremendously firm yet sculptable. Absolutely the best for me.
Finally, in the past, I have tried;
Magic Sculp; good, but it gave me an irritant reaction to my skin, hence I stopped using it. I would place as the best epoxy style, but under pro-create.
Aves Apoxie Fixit Sculpt; very similar to Fix-it, I would say that maybe slightly worst, as was softer. Much harder though.
Standard ironmongery epoxy putty (Aki, Leroy Merlin, etc); somewhat worse than any proper epoxy putty, more solid when dry, but very soft usually always before. Also gave me allergic reaction so I stopped using them. I believe Milliput fits this category, I havent tried doing soldiers with it, only rocks and terrain and some minor object.
Now I want to try Kato, which they say is the best polymer clay, and Brownstuff, which they say is similar to Greenstuff.
For smoothing, I always use baby oil / mineral oil, works wonders, specially with green stuff that doesn't really react much with water.
I wonder, I am missing some?
