could you mix something in with Sculpey to make it stronger? Answered

Sculpey is great stuff, easy to use, but after it's baked it's vulnerable to breaking if you don't make it thick enough. 

Any one have ideas on an additive to mix in with it that could make it stronger?

Thank you


Use Fimo instead, it's also a polymer clay but it is a lot stronger.

Maybe.. thank you for the suggestion.

I've been wondering about this myself. I have a ton of sculpy--some of it I bought before I knew better and a bunch of it was given to me. It's frustrating to work with but I don't want to throw it out. I was surprised to read that Mica could actually strengthen the clay. The fiber ideas could probably work--and could even become part of the whole "look" depending on what and how they are mixed in or applied.

I have also been told--and had success with mixing sculpey in with the other better polymers. I don't know if there is a specific ratio that works best.

Any other add-ins? Ideas?

how about a wire rebar structure?

you could even insert the wire after your sculpture and only have to cover up little tiny holes the diameter of the wire with a little sculpey

sculpy or fimo makes a varnish type finish I think

Traditional way to make materials stronger (tensile strength) is to mix fibres in with the material.

Glass reinforced plastic uses glass strands - readily available BUT it tends to stab your fingers if your hand forming.

Horse hair - works well with clay and mud for bricks.

Look around and experiment.

This might not work depending on the colour you want but I recently made some costume accessories out of webbing, and before melting the end of the webbing straps they would fray into bundles of very thin fibres which were surprisingly strong. Grab some cheap webbing (preferably not your car seatbelts), cut an end and try teasing some of the fibres out?

Interesting notion. Maybe the plastic netting that lemons come in?

Waaay too coarse. You can get polyester fibres for reinforcing concrete which are very fine too.

Another interesting idea. although it is dangerous to use by itself - it can lead to something like silicosis.  It is an ingredient in certain kinds of glittering cosmetics as well.  

If you're habitually exposed to it, yes, it might.

Also, some sort of epoxy finish coat may help to avoid breakage.
