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

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

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.

Well , I searched a bit on the net,  and I think the answer might be.... mica.

Do a search for "mica flakes on EBAY.  Looks like the stuff is not too hard to find
and it's not  super pricey.

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.

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

Maybe.. thank you for the suggestion.
