Polymer clay remains workable until cured. Curing occurs at temperatures from {{convert|265|°F|°C}} to {{convert|275|°F|°C}} sustained for 15 minutes per {{convert|1/4|in|mm}} of thickness.<ref name="Roche"/>  This temperature is significantly less than for mineral clays and can be achieved using a home oven. Professional polymer clay brands shrink very little when cured<ref>{{cite web |last1=Cahill |first1=Phyllis |title=Does Polymer Clay Shrink? |url=https://polymerclayjourney.com/2016/12/27/does-polymer-clay-shrink/ |website=Polymer Clay Journey |access-date=13 December 2018}}</ref> Brands of polymer clay include [[Cernit]], [[Oytra]], [[Fimo]], [[Kato Polyclay]], [[Sculpey]], [[PVClay Brasil]], [[Crafty Argentina]] and [[Cosclay]].

A home pasta-making machine is a popular multi-purpose tool for polymer clay artists. It is used to create sheets of uniform thickness, to mix colors or create variegated sheets, and to condition (soften) the clay.<ref name="Roche"/> Polymer clay generally needs to be conditioned before use. This involves kneading the clay by hand, passing it between two rollers, or using a low-shear mixer to break up any resin particle adhesions. Once conditioned, the clay will remain pliable until the particles eventually re-adhere.<ref>{{cite journal|last1=Cheraghian|first1=Goshtasp|title=Synthesis and properties of polyacrylamide by nanoparticles, effect nanoclay on stability polyacrylamide solution|journal=Micro & Nano Letters|date=1 January 2017|volume=12|issue=1|pages=40–44|doi=10.1049/mnl.2016.0419}}</ref>

Oven-hardenable PVC plastisol, "liquid polymer clay," is a complement to polymer clay that can be used as an adhesive to combine pieces, or to create various effects. Pigments, chalk pastel, and regular polymer clay can be added to make colored liquid clay. The liquid can also be poured into molds to produce cast parts. {{citation needed|date=August 2019}}
