Casting with silicon. Step By Step

Step 1.

A wooden box need to be made to fit the item you will be making a cast of. The box needs to be solid so that there are no leaks, but with one end open to pour in the silicon

Step 2

The microwavable silicon comes in a pack as below but any silicon can be used just be sure to check the melting/mixing instructions.

The silicon then needs to be poured into the box which should contain the object you want to cast, and left over night approx. – 12 hours.

Step 3.

The box can now be ripped off.

Very carefully you should use a sharp craft knife to cut into the set silicon mould, three sides of the mould need to be cut into right up to the surface of the object, enough so that the object can then carefully be pulled out.

Step 4.

Now the mould is empty and if it has worked out there is a hollow print on the insdie in the shape of the object you would like to cast.

Which material are you going to cast your object from? Resin, wax, plaster, ?? Pour it in leave for its individual setting time and pull out carefully once it is set!

Done!

If you are extra careful you can use the mould multiple times.

Step By Step.

For a previous piece I made some teacups and saucers from everyday tangible materials such as cello tape, masking tape, cling film, regular household gloss paint and a sharpie marker pen.

Step 1

Choose the object or shape that you would like to recreate.

Step 2

Cover the whole object in cling film very tightly and into each nook. The closer and tighter the cling film the better the final outcome will be.

Step 3

Cover the cling filmed object with strips of cello tape. Keep the tape close and tight around all the areas of the objects especially with unusual shaped things like the cup I have done.

Step 4.

Find an even area of the object to very carefully slice through the tape and cling film with a craft knife.

Take off the pieces from the object inside so you have two free standing hollow pieces like below.

Step 5.  

Use small strips of cello tape to join these hollow pieces back together.

Step 6.

The new object can now be decorated however you want.

Material and making

Over view of thoughts….

Continuing a theme of previous works through collection and the tea cups.

I am likely to get lost in the making of the objects rather than the concepts and contexts to the work. Look at material use and material values which are brought when using them.

Look at using wax like with previous works..

Thinking about scale of the piece and a mode of presentation for the work.
