Melting Cups

3/14/2013

These were fun to make because you get quick results.
You'll need cups like this, they are soft whitish plastic. We tried the clear plastic cups - FAIL, they don't melt. These were from the dollar store.

Preheat your oven to 350f, they didn't have any smell to them while melting

Draw designs on your cups with PERMANENT marker, we used Sharpies. Then I placed them on a cookie sheet lined with parchment,
I didn't want them to stick and they never did. We spinkled a little glitter on the top of a few of them, some of the glitter stuck as it melted but some also came off when we touched them, but a girls gotta have a little bling.
I have to mention, I did have a 13 year old boy make a couple of these before he became too cool and left to go hang with his friends :)

You can't do anything wrong, I think they all looked great!

15 seconds in the oven and they look like this.

They were done in under 1 minute and could be handled within 15 seconds. Cup cools down fast but remember the cookie sheet remains hot. While still warm from oven you can press down on them to make them a little more flat if you wish - we liked them a little wonky, like us!

Aren't they pretty? I thik the more detail the prettier
they are but anything works.

Now, you could easily punch holes in them, hang them
use them as gift tags or decorations
but these girls wanted to keep them like this to give to friends.

Have fun !

Do the colors run off after it's melted?

Has anyone tried this in the microwave? Did they come out good? If so how long do you suggest? I’d like to make them with the kids at work, but only have access to a microwave.

They don't smudge at all after melting but we do have marker coloured finger tips from decorating the cups. There were a few smudges prior to melting but I think that's what makes them 'crafty'.

Do you know what # for recycling they are?

12/12/2013 01:54:05 pm

Hi Rebecca,
I have no idea what # they are but I will check it out and let you know within a couple day. Thanks!

I have been told recycling #6 is the same as shrinky dink plastic that you purchase. YAY

They are #6.

I just checked some in the store and they are #6 recycling, hope this helps.

Is the temperature in fahrenheit or celsius?

5/3/2016 03:44:32 pm

Hi Lisa, that temp is 350f , I've fixed that in the directions.
Thank so much for visiting!

Do they fade in the sun?

2/9/2019 02:27:20 pm

Yes

I guess it would depend on the type of markers you used. When made with sharpies we had them 2 years outside with very little fading.

This is a GREAT idea. I teach small easy craft classes at a community center in mexico. We are using all natural and recycled goods in our garden which is a work in progress. This is a great use of an often thrown out plastic that ends up on our beaches. Our classes teach our community to have fun with things rather than tossing it into the garbage .. make ART not GARBAGE.. thanks can't wait to see the kids do this.. I love super simple crafts that are multifaceted as in recycled garbage into fun homemade colorful whimsical personal art pieces.. so excited !!

That sounds fantastuc. I make mainly sewn things from recycled fabric and other items. I even use the innerctubes from bicycles...

These would be great for Dot day projects!

Do these have any danger with chemical fumes while heating in the oven? Would you need to do these in a toaster oven dedicated to crafting?

1/26/2019 09:10:57 pm

You can do these on a cookie sheet on the bbq on low or in a toaster oven outside. There are some fumes but we have a wall of patio doors and windows near the oven.

“When plastic waste and food waste are burned, they produce dioxin and furan. ... If dioxin is inhaled, it can instantly cause coughing, shortness of breath and dizziness. Long-term exposure to dioxin can also cause cancer. Another harmful effect of burning waste is pollution, as it can damage the ozone layer.

Finally somebody pointed that out...

Dioxin is not formed at the melting temperature of 350 F...it is formed at 350 Celsius, not Fahrenheit...350 C = 662 F. Melting is not the same as burning (incinerating). Be careful of your "facts."

Do they maintain any of their translucence or does the melting down/condensing make it too thick for any light to get through?

2/11/2019 04:39:04 am

They aren't as transparent as they were when they were cups, you are right, they become thicker.

I've tried these and my cups don't keep their shape. What am i doing wrong.

2/12/2019 12:22:24 pm

Hmmm, I don't know they've always worked for me. Are you using the right cups?

I did these in a church art group. One oven produced round discs, and the other produced oval discs. Maybe it has to do with the air flow/ hot spots in the oven.
My home oven made oval discs.

It’s probably the levelness of your oven or the pan you are using. If it isn’t level the would slump to one side or another instead of melting straight down.

How bad does it smell? When they are melting

Mary Walling

There is no smell or smoke. Its similar to melting the shrinky-dinks

I think you could use a hole punch near the top to get a hole before they melt. Have you tried that?

Jennifer

We just made these at 4H camp used small white plastic Dixie cups punched a hole and added dental floss so we could add names of who made and then also hang a heat gun would take a while and probably not be even?

Becky

Can a heat gun be used instead of the oven?

What is to be done with them after they are melted? I'm having trouble imagining a purpose for these cute discs.

I am going to do these for plant markers in my garden! String them to make a cute all weather garland. Since they're translucent, but not transparent, they'd make a cute window privacy cover if tied together in a grid. How about a coaster, perhaps? Glue it to some cork or felt so it doesn't slip. Large necklace charms for kids. Play medals! Like pretend Olympic medals, maybe!

I'm thinking they could be cut Halloween decorations to make with my grandkids!

I am worried about the toxic fumes put off by the melting plastic. I have read some reports about that with plastics in the dishwasher. Especially doing this around children.

I have made these the last couple years with my Girl Scout troop. They love making them and watching them melt. We use the 3oz. white cups. I have made them in an electric oven and gas oven with much success. I tried a convection oven and that was not successful. I am curious if anyone has tried them in a microwave?

We tried it too and it worked out perfect!
