How to make a double mould?

Moulds are very useful for repetitive tasks for example if you work with polymer, paperclay, ceramic clay, papier maché,...
Making a mould is not difficult, it's just a bit messy so you better have everything you need prepared beforehand.

This is what you need: plaster, empty icecream containers, liquid beeswax, clay, scissors, knife, doublesided tape, tape, modelling materials (only if you mould claywork), plasterlocks, paintbrush, water, towel. Be sure to protect your surface with a plastic tablecloth and wear an appron if you're messy.The most important thing when you make a double mould is marking the exact middle of the object you want to mould.Make a little bed for the object to lay in. I do that by rolling out a piece of clay and draping it around the object.
Then you need to make sure that it closes tight to the marking line by adding clay and making sure that no plaster can go underneath.
It's a very precise task and it always takes me ages...
Done! I'm satisfied with how it looks.
Now there are two ways to make the locks for the moulds. These are plastic ones that you press into the sides. The advantage is that they make the mould more durable. So if you are going to use it often, I advise you to buy some of these.
The second way is to press a round object into the sides of the object. Plaster will go into those and will give you a bump.I will use the mould a lot so I chose to work with the plastic locks.
Build with plastic a tower around the clay and make sure that there is enough clay on the bottom so no plaster can escape.
Pour the plaster into the construction and let it set.
After about an hour, I open up the construction and you see this...
Take away the little clay bed you made around the object.
Then make sure that the object looks all nice and happy again. You can do that by smoothening it with a credit card or a slightly wet brush.
As I didn't do a very good job on the plastic slots, I decided to add some extra clay around it. It won't matter for the result of the mould.
Since you'll be pouring plaster onto plaster, you will need to add liquid beeswax onto the plaster.
Build the little construction again and fill it with plaster.
After about an hour, this is the result.
Oh, and the object is a full lump of clay - it's not hollow inside as the pressure from the plaster would make it go all wonky.
The mould will need to dry very well before you can use it. I put it on the radiator.
It will be great for much future fun! :)
Enjoy moulding if you start and if you have any questions, please don't hesitate to contact me.

How to do plaster carving?

I love sharing things that I love doing myself, so I made another how-to.
This time about plaster carving. It's such a simple way to reach wonderful results. It's especially a very fun activity to do with kids.

Here is what you need: wine corks, nails, a piece of plaster, a piece of tracing paper, a pencil, a nice drawing and if you have 'em, all kinds of cutting tools like lino cutters, knife,...
I'm terrible at drawing, honestly, if I would draw a pig, you probably would think it's a monkey.
So, I often use other people's art to help making what I want. This time I'm using AnnaRubyKing's printable colour in pages. I chose to trace the branch with a pencil onto tracing paper.
Then I turn around the tracing paper and I rub with a pencil the drawing onto the piece of plaster.
This is the result:
There are several tools that you can buy especially for plaster carving but if you are only going to do this once in a while, why don't make your own tools?
You need some nails, wine corks and a hard surface for this. Put the nail with the sharp side into the cork and press firmly. Now you have a hole.
Then take out the nail and press the head of the nail into the hole. This is a bit hard but if you press it onto the hard surface it's easier. Now you have a handy grip to carve into the plaster.
It's much safer too if you work with children. You can also put a needle into it, this makes very fine lines.
These are some of the tools I use. The branch like tools are handmade too from nails and hazelnutbranches. They are very handy but a bit more tricky to make.
Outline the lines of the drawing with a sharp knif or needle. You will have to blow lightly to remove the excess plaster so you can still see your drawing.
Then create some depth into the plaster. I used a lino cutter to do this.
OK, my branch looks slighty different then Anna's drawing but I like it!
With a pencil, I added some lines into the plaster and with a handmade cork-tool, I'm going to carve the lines slightly deeper into the plaster.
Then I'm going to press a piece of clay into the carved plaster and see if I'm satisfied with what I just made.
I take the clay away...
Jip, I like it! If not, you do some more carving and repeat these last two steps.
I tear away the sides to get rough edges and make a hole into the pendant with the lino cutter.
Tada! Let it dry and fire it in the kiln. If you don't have a kiln, you can do this also with polymer clay, papier mache or air drying paperclay.
Have fun carving your own plaster!

How to make a single mould?

As I have been making moulds the last couple of days, I'd thought I'd share with you how to make them. Moulds are very useful for repetitive tasks for example if you work with polymer, paperclay, ceramic clay, papier maché,...
Making a mould is not difficult, it's just a bit messy so you better have everything you need prepared beforehand.

This is what you need: plaster, empty icecream containers, liquid beeswax, clay, scissors, knife, doublesided tape, tape, modelling materials (only if you mould claywork), paintbrush, water, towel. Be sure to protect your surface with a plastic tablecloth and wear an appron if you're messy.
I'm going to mould an existing bowl. A bowl is an easy thing to mould. That way I can make loads of bowls like this...
Put some doubleside tape on the edges.
Press the bowl onto the placemat so that it sits firmly. Now no plaster can go on the inside of the bowl.
Since you'll be putting plaster on the bowl, it will need to come loose afterwards. That's why you need to put some beeswax onto the entire bowl. If you use clay, you don't need to do that as clay is cellular and will come off easy.
I always safe empty ice cream containers as they come in very handy for moulding. Besides, it's a good excuse to eat icecream. :) Cut off the upper part of the container and place it over the bowl.
Take some clay and press the clay firmly around the container. This way, no plaster can escape.
Make the plaster ready to pour in the mould. The plaster is good if it has the same viscosity then yoghurt.
Place your hand above the bowl and pour the plaster via your hand into the container.
Let it set until it's hard.
Take away the clay and try to get the real bowl out of the mould. If this is hard, you can hold it underneath running water so that it's easier to get it out. Let the mould dry before using it.
If you have left over plaster, don't throw it away but poor it into a container and let it set. You can do fun mouldcarving like this.

Next time I'm going to show you how to make a double mould so stay tuned! :)
