Hi folks,

I've been experimenting recently to improve my sculpting (which is code for doing a shedload of sculpting and achieving nothing worth showing off!) and wanted to hit up the community with a query;

I've seen quite a lot of people talking about their various mixtures and favourite ratios etc for the various modelling putties out there.
Several times I've seen people talk about a mix of Kneadatite (greenstuff) and Sculpey (or fimo etc - ovenbake clays).
Nobody says whether they have to bake this mix to set the sculpey component. Is it necessary to bake it?


Thanks,

Possum

Hey Possum,

I've not seen anything about mixing greenstuff and sculpey. However, I have seen quite a bit of mixing greenstuff and miliput. Miliput (depending on the type) is a sculpting clay that can be mixed with greenstuff to make it harder/sharper, and easier to sand.

There is also "grey stuff" (Procreate) which can be mixed in different proportions from the ribbon to make lighter or darker greys, which have different properties.

I don't think I've ever heard of greenstuff going in the oven (which you would need to set the fimo), it might not do so well.

Green Stuff becomes 'runny' when exposed to heat, this oily liquid oozes out while the form loses shape and thickness. Green Stuff turns dark then brown when exposed to serious heat.

Mixing it with another putty may alter this reaction. I was using a space heater to speed up the cure time on some parts made with a Magic Sculpt and Green Stuff mix, did not see any problems.

That said, if you really want to know the answer, test with a sample before you try with a model. Anything involving Sculpty has to be cured.

You can mix greenstuff with sculpey (as you noted, many modelers have said they do), but you have to be careful on the ratios or else it will never cure. Sculpey just increases the working time. A 1:1 mix will never harden, for example. A 1:5 mix will, but it will still be pretty soft. More commonly, people mix epoxy to epoxy for different consistencies.

5% green stuff 95% green stuff . Ths should help https://www.dakkadakka.com/dakkaforum/posts/list/771248.page

Given that the temperature for curing Sculpey is lower than the temperature for vulcanising rubber, and green stuff has been used in vulcanised rubber moulds for decades, it doesn't seem like it should be an issue.

Myself and the sculptors I know tend to just stick to one material. Greenstuff and milliput are too soft for my preferences. Rather I just use Procreate for everything and vary up the mix as necessary. The drying time is also far quicker than Greenstuff, which whilst doesn't give you the free time as something which only hardens in the oven, lets you plan out a model in short steps instead. I'd rather do a little bit at a time than have to heat the model for a bit after every layer's done (god forbid anyone's doing multiple layers at once, that's just asking for trouble).

Personally the most I mix materials is the odd bit of greenstuff for very small items, as I don't generally go with so much "white" in my Procreate mix to have that sort of consistency. As will I use materials similar to Liquid Greenstuff for any cracks, etc. Otherwise anything else just seems like a hassle.
