(for parents): polymer clay
what is polymer clay?
Polymer clay is an engineering wonder. it has extremely good properties for sculpting, and then cures in your oven1, where it will hopefully be fairly durable after (okay it might not be the most durable thing ever, more on that).
i grew up using it and it is still one of my most favorite hobbies. polymer clay rules. (note, i need to insert some pictures, which i haven't)
polymer clay is also like a gift that keeps on giving if they take to it. i made a lot of stuff for my mom and i'm sure she still has one or two in her office. and i got to decorate my room with them and continue to appreciate my creations even into highschool etc. in fact i would love to have them here with me now, i should investigate what has survived.
when is your kid old enough for polymer clay?
polymer clay is very very deep in terms of the levels of engaging and mastering it. like very extreme. you can go from using it as premium playdoh, to surreal amounts of detail (the same clays you would get for a kid are also used by visual effects studios).
so i would say as long as they aren't gonna put it in their mouth then they are old enough.
note: playdoh is stupid. if your child is too young for polymer clay they should use this: model magic.
model magic feels great to touch, it's super satisfying. feels like something out of a tiktok lol. dries to be a relatively light durable toy. it's a good product!
playdoh is messy and crumbles into nothing when dry. lame!
signs that it's time for polymer clay over air dry clay
- kids display fine motor, start showing a lot of detail in their drawings (for example when i was a kid i would draw monsters and cover them in hundreds of individual scales). or another sign, i would make detailed little dioramas with various auspicious items in my desk drawer.
- kids display interest in proper projects with multiple steps (for example a basic polymer clay project could be making a tinfoil armature and then putting clay on that)
- kids display interest in creating permanent items, gifts for others. or for example if you notice them creating something and they already have an idea of where they want to store it, that would be a sign it's time to level up.
- kids display aesthetic tastes
- kids display interest in sticking to a crafts project for at least an hour at a time.
- kids can be trusted to maintain cleanliness (polymer clay is less messy&risky than paints though to be clear)
analogous to standard-size lego vs duplo blocks. the actual age is gonna vary a lot probably.
(i am being needlessly thorough, i just like clay.)
brief clay note: another thing about clay is that i think it is just actually way easier for humans to do than drawing. i very consistently surprise myself with how good i'm able to make things on a first try, and i find this is a common reaction to trying clay for others too.
what polymer clay should i get my kid?
short version: i would get this or something like it.
clays vary a ton, mostly on three things:
- firmness— some stay soft and pliant; other, more “professional” clays need a lot of force to squish before they're workable.
- durability once cured — some hold up as real toys, others are surprisingly easy to break.
- color range — some variants only come in limited colors, others in a large amount.
a couple of specifics: i grew up on sculpey III— it stays nice and pliant, but it breaks much easier after curing than pretty much anything else they sell (i have no idea why), so i don't think i recommend it over premo. soufflei think stays pliant too, and is also durable when cured — so that's kind of the best of both.
if there's any ambiguity about whether your 6+ yo kid would prefer sculpey vs an air dry clay, imo just get the sculpey. signs they might prefer the model magic: they've got a particular interest in making things larger than the size of an apple, they just want to squish something, or they're kinda bad with mess. i mean whatever, get both. clay rules.
- unlike earthen clay, polymer clay doesn't expand or contract or anything while curing. it can be hollow. in fact, it's common to make an aluminum foil core that you put clay around. so if you have ever heard of clay mugs exploding in the kiln or whatever, i just want to point out this is not relevant here. ↩
