Experimenting: Melted Crayons

Do you remember our version of melted crayon art?
It's my most popular post
and
a lot of people have been giving it a try
which is GREAT!
I've been getting a lot of questions about it
especially about the oily residue that seems to seep underneath the tape
and
leaves a ring around the wax
like this:
It's pretty undesirable for those making the melted crayon art to be displayed on their walls
so
we decided to experiment with different colored crayons 
and 
different types of paper to see which would give us the smallest and biggest oil ring

We started with foamcore board
which is what we used as the base for our melted crayon art
You can't tell from a distance that our crayon art has the oil around the edges where the tape was
but if you look closely you will see it
You can't see it very well in these images either
but what you can see is that the apricot color on the left
has left a white-ish color on top of the red
and on the right you can see the red pigment separating from the wax
All the crayons I used were Crayola
They use paraffin wax and powdered pigment to make their crayons.
From what I gather about paraffin wax is that the liquid version is mineral oil
which would explain why there is an oily residue when you melt it
The sketch paper soaked up the oil well creating big oil rings
There was a bigger ring around the apricot color than the red
From the back you can see the oil seeping through
The vellum paper performed the best
it's made from plasticized cotton and therefore resisted the oil like a plastic would
it didn't soak any up and the crayon edges were very clean
If you are making crayon art to be displayed on your walls
I would recommend having a sheet of vellum backed by foamcore board
so you get the vellum quality but the sturdiness of the board
I would also recommend using masking tape with vellum instead of painters tape
I think it would stick better to the paper with no gaps for melted wax to get under
Look!
No oily residue seeping through the back
We tried foam sheets
which I don't think anyone should try
they were too floppy and the tape didn't stick worth a darn
Though there was no oil ring and the lines were very clean
The construction paper soaked up the oil like the sketch paper did
leaving big rings of oil
The cardboard soaked it up a bit
I think the fact that the cardboard fibers are tighter than paper like construction paper helps the oil to not spread
You can sorta see in the green wax that it kinda looks grainy around the edges from the pigment
The first picture in this post is from the watercolor paper
There was a larger ring of oil around the yellow was than there was around the brown
but you can see on the back that it soaked through under the brown
The glossy fingerpaint paper surprised me the most I think
It soaked the oil up well but the oil didn't spread much away from the wax
For some reason though the glossy paper made the wax and pigment separate quite a bit
You can clearly see the pigment particles floating in the clear wax

Overall from the experiment we found that the paper with bigger fibers soak the oil up more leaving a bigger ring.
The darker colors seem to separate pigment and wax more than the lighter colors. 
I was looking for whether or not lighter colors or darker colors left a bigger ring of oil but the results for that were pretty inconsistent.

We didn't try stretched canvas because we didn't have any on hand but from what I can tell with the paper is that the fiber will soak up the oil pretty well. I would suggest using a canvas that's been primed first, that way the oil can't soak into the fibers

Have you done melted crayon art?
What has your experience been with the oil ring?

{Easy} Yarn Spider Webs

Halloween is one of my favorite holidays
I like the creepy decorations best
and
what's more creepy than the thought of
gigantic spiders!?
Here is an easy way to make spider webs with yarn
We made one last year before I started the blog
and 
it was so fun I decided to make them every year
Here's how I make them:

TP Roll Mummy {Prints and Garland}

October is upon us!
Time for scary ghouls and goblins
ghosties and witches
vampires and zombies
and
mummies!!

My mom just bought a book for the girls called
by Michael Rex
He writes parodies of popular children's stories
this one is a parody of The Runaway Bunny
 Since we were reading about mummies we decided we wanted to make some
 You need toilet paper rolls
and
gauze
 Then we decided to make prints with them
So I set out some black paper and white paint

When the prints were dry I cut them out
C glued googly eyes to them
Then colored over them with oil pastels to "age" them
 
Waiting for their eyes to dry
We punched two holes into each mummy and strung them up with yarn
My husband says they look like the Mini Wheats characters
 The toilet paper roll mummies became all stiff and kooky looking 
because the way the paint dried on the gauze
So C rubbed the oil pastels on them as well
and 
glued on googly eyes
I think they look really neat!
Our first Halloween decorations of the season!
 BOO!

These mummies are scaring over at these linky parties
