Polymer clay, additionally referred to as polyclay or fimo, is a modeling materials that you would be able to remedy or bake at house in your common oven. In the present day is a deal with Ideas and Tips for getting the most effective outcomes when curing your tasks. Take a look at the opposite articles, too. Half 1 was on Selecting your Oven and Half 2 was about Temperature.

How Lengthy Ought to I Bake Polymer Clay?
It’s no surprise that individuals are confused about this one. Right here’s what varied packages of polymer clay inform you about baking length:
- Fimo: half-hour
- Pardo Artwork Clay: Minimal of half-hour
- Cernit: Roughly half-hour
- Kato Polyclay: 10 minutes
- Premo: half-hour per 1/4″ (6mm) of thickness
- Sculpey: quarter-hour per 1/4″ (6mm) of thickness
These are absolutely the minimal instances that you need to use, and the really helpful 10 minutes for Kato is simply plain inaccurate. Polymer clay turns into a lot stronger when it’s baked longer than these minimal instances. You can not burn or injury polymer clay by baking it for a really very long time, even hours, so long as the temperature is right. Not like meals, which can burn if left too lengthy within the oven, polymer clay is not going to burn if baked on the right temperature. The limiting issue, although, is that gentle colours of polymer clay will darken and brown with longer instances within the oven. It doesn’t injury them, however it can simply break your impact, particularly for those who’re working with gentle or translucent polymer clay.
I all the time advocate baking no less than 45 minutes per 1/4″ of thickness and even longer for thicker items. For optimum outcomes, do what works for you, not what a package deal says.
Undecided you’ve baked your piece lengthy sufficient? Examine how one can inform in case your polymer clay is baked by testing the flexibleness right here.
Place within the Oven
While you put your polymer clay within the oven, attempt to heart it as removed from any heating ingredient as potential. You need good air circulation round your objects in order that the warmth can distribute evenly contained in the oven. Put it on the middle rack, equidistant from the weather, and hold it away from the oven’s partitions. That is clearly harder in a toaster oven because the baking chamber is so small. But when components of your venture are too near the heating ingredient, it can burn.
Defending your work from the warmth
As anybody who has ever held their hand above a range’s heating ingredient can attest, it will get awfully toasty! Even when the general temperature within the oven stays the place you set it, each time that heating ingredient cycles on, it glows crimson scorching and might singe your polymer clay items in the event that they’re too shut. Some ovens don’t regulate this very properly and the ingredient will scorch issues, fairly badly at instances. One of the best ways to guard your lovely art work from baking disasters is to guard it and protect it from the warmth by conserving it lined up.
I exploit an aluminum foil cake pan, most frequently the 8″ x 8″ measurement as a result of my 6″ ceramic tiles match completely within the backside. (These of you outdoors the US might want to discover the sizes that work for the supplies you might have the place you’re. Within the UK, I do know you will get 150mm tiles and 240mm sq. pans.) For bigger tasks I exploit bigger pans and tiles. You would use a sheet of aluminum foil. Or a lined roasting pan. Or an the other way up pan. Masking your work protects it from the heating ingredient and it additionally helps hold the warmth contained at a gentle stage contained in the pan, resulting in a extra full and dependable remedy.

One other incredible bonus of utilizing a canopy is that the chemical smells that come from baking polymer clay might be significantly contained. The few instances that I’ve baked uncovered, my husband has come to me, apprehensive, as a result of he may odor the clay and thought it was burning! (It wasn’t.)
One different good bonus that comes from utilizing the foil pans is that I’ve a canopy for my unbaked items within the studio. Generally I’ll have the pan sitting there for days till I’ve made sufficient items to bake. The duvet retains the mud and curious kitties from ruining my clay.
In the event you use a toaster oven and have a tiny house, you can use the tiny aluminum foil pie pans the identical means that I exploit the bigger pans. Any pan with a lid that’s oven protected may very well be used to guard your clay whereas baking. Preserve your eye open for a small unpainted metallic field, or perhaps a tin. Run it by means of the oven by itself first to ensure it can deal with the warmth, although, simply to ensure.
Sustaining a Fixed Temperature
Convection ovens are significantly better at conserving a constant temperature, however typical and toaster ovens use a scorching ingredient, biking on and off, to maintain the house heated. The radiant warmth from the ingredient can burn your clay, as I’ve already acknowledged, however there’s additionally the issue that curing of your objects could be inhibited if the temperature doesn’t keep excessive the entire time. In case your oven is a kind of that will get pretty chilly earlier than the ingredient kicks again on, it may be useful to position ceramic tiles on the rack in the course of the oven. This can act as what’s referred to as a “heat sink” to assist maintain and evenly distribute the warmth. You would additionally use an previous pizza stone in case your oven is massive sufficient.
That is why I exploit a ceramic tile within the backside of my foil pan baking system. It helps hold the temperature fixed. I additionally use my ceramic tiles as work surfaces, if this can be a new concept for you, you may need to examine how ceramic tiles are considered one of my most indispensable instruments.
Assist and Protecting Materials
While you place uncooked clay on a glazed ceramic tile after which bake it, the locations the place the clay touched the tile might be shiny. To stop this, merely place your merchandise on a bit of scrap copy paper, an index card, or a bit of card inventory. Don’t fear, the paper is not going to burn. However ensure that it doesn’t have any printing or writing on it because the inks may switch to your clay.
In the event you’re baking spherical beads, setting them on a flat floor is a recipe in frustration! To maintain them from rolling far and wide, merely accordion fold a bit of clean copy paper and set your beads within the folds. They’ll keep in a single place and so they gained’t have shiny spots.
One other methodology is to make use of a bit of polyester quilt batting. Once more, it gained’t burn within the oven, and it retains your items from getting a shiny spot. Batting is a good software, too, for those who work with sculpture and must assist components of your piece throughout baking. Simply use numerous polyester fiberfill to prop all of it up.
One factor to notice about utilizing paper, although. Don’t depart your artwork piece on paper for very lengthy earlier than you bake it. You may discover an oily spot on the paper…that’s the liquid plasticizer that’s leached out of your clay. A small quantity gained’t damage your clay (be certain that to discard the paper afterward, although). But when extreme quantities of plasticizer are leached out, it would weaken your piece.
How to stop browning of your clay tasks
Translucent and lightweight colours of polymer clay are very inclined to turning brown throughout baking. This isn’t a sign of burning and isn’t harmful, however it’s irritating. It’s simply a kind of issues it’s a must to work round and there are some issues you are able to do to stop, or no less than decrease the issue. Earlier than we get to these, although, just remember to are baking on the proper temperature and are masking your items throughout baking to stop the heating ingredient from damaging your work. Listed below are just a few different issues you’ll be able to strive.
Bury your Beads
One other technique to guard your polymer clay from the warmth of the oven is to bury them in baking soda (bicarbonate of soda) throughout baking. Different individuals use cornstarch or salt. To do that, simply pour an oven-safe bowl of your favourite powder, dig a gap, and put your beads inside. Put the entire thing within the oven to bake. After baking, you will have to rinse the powder off the beads. Some individuals report that cornstarch is more durable to rinse off and leaves a white residue, so that you may desire to make use of baking soda if that’s the case. Regardless, don’t depart the beads sitting round unbaked within the powder for very lengthy, although, for a similar motive as with the paper above. The plasticizer can presumably leach out of the beads, leaving them brittle.

Experiment with Time and Temperature
Greater temperatures and longer bake instances result in extra browning. So decreasing the temperature or the length of baking can remedy the issue of browning. However, as I’ve mentioned beforehand, that may additionally result in weakened and underbaked tasks. I recommend fastidiously experimenting with minimizing the baking time and temperature whereas on the identical time monitoring the venture’s power. It is advisable bake lengthy and scorching sufficient to be totally cured and robust. Attempt the opposite methods first, and for those who nonetheless have unacceptable browning, then strive experimenting with the time and temperature of baking.
Stopping Plaques and Cracks
Plaques are whitish areas that seem in the course of a bit of polymer clay after curing. They appear like they’re air bubbles however appear to occur when there was no apparent air trapped within the uncooked clay earlier than baking. It’s extra apparent in translucent and lightweight coloured clay. It’s been recommended that they’re attributable to water vapor or air amassing within the clay throughout curing and that they’re attributable to or exacerbated by sharp contrasts in temperature throughout baking or cooling. You will notice extra plaques whenever you’re baking too near the heating ingredient.
Are you able to bake polymer clay greater than as soon as?
A standard query for these new to polymer clay is “Can you bake polymer clay more than once?” The reply is YES! There is no such thing as a motive you’ll be able to’t bake a bit of clay as many instances as you want to. Actually, for advanced items, it’s widespread to bake components of the piece individually after which assemble and connect them after baking. It’s additionally completely effective to connect uncooked clay to baked clay and bake that. Generally it’s the one means you will get sure results.
Excessive Altitude Baking of Polymer Clay
In the event you stay at a excessive altitude, then you definately already know that the legal guidelines of physics can do some unusual issues to your baking instances and temperatures. As a result of baking instances for meals must be adjusted at excessive altitudes, many individuals assume this is identical for polymer clay. It’s not. There is no such thing as a water in polymer clay, so the air strain variations of altitude are irrelevant.
Alternate Strategies of Curing
Don’t use a microwave to remedy polymer clay. It’s the fallacious type of heating course of. It’s not going to trigger sparks or something like that, however it can trigger smoke when it burns! Learn extra about for those who can bake polymer clay within the microwave in my article about it right here.
For some motive, there’s a controversy about utilizing boiling water to remedy polymer clay. Some individuals say that it really works, however that simply isn’t real looking. Water boils at 212°F (100°C), which is a temperature too low to remedy polymer clay. You’d suppose that including extra warmth would elevate the temperature of the water, however in actuality, it doesn’t. Blame physics. Now some individuals will say that boiling for a very long time does give a whole remedy for polymer clay. I’m very, very skeptical of this.
However, I can conceive of why you may need to boil a polymer clay sculpture, as an example, to permit the water to assist the merchandise lengthy sufficient to partially remedy. This may be useful with advanced skinny projections or items that might ordinarily be too floppy to bake with out the assist of the water. You’d then totally bake the merchandise at a correct temperature within the oven. However that’s not one thing most of us are going to be coping with.
A warmth gun is a priceless software for working with polymer clay. You possibly can spot remedy polymer clay with a warmth gun however it’s a must to be very, very cautious to maintain the gun transferring always and never get too near the clay. Warmth weapons produce sufficient warmth to scorch and burn polymer clay inflicting it to blister and switch black (and produce irritating fumes). Sure, I hold my head in disgrace right here. I’ve accomplished this. However so long as you’re tremendous cautious to keep away from burning, you’ll be able to kind of “soft cure” clay to get it to solidify. You may use this system if utilizing liquid clay to assemble a sculpture, as an example. Nevertheless it’s not a whole remedy and you’d nonetheless want to completely remedy your venture within the oven.
Cynthia Tinapple does use a warmth gun to remedy her polymer in place within the picket bowls she creates together with her husband Blair Davis. However she additionally makes use of a digital thermometer to ensure the clay is definitely reaching curing temperature. For many of us, this isn’t a typically dependable means of curing polymer clay.
Nicely that’s all I can consider. You must have a fairly good concept of learn how to bake polymer clay. Now go make one thing lovely!
