Experimenting with the laser cutter

Today I have been etching my collection of photographed textural matter onto perspex with the laser cutter.

At a later stage I would like to experiment with printing from these perspex etchings.

To see the results of my perspex printing experiments, please see Perspex etchings and prints.

Experimenting with latex

Today I am experimenting with latex.

I have used my collagraph plaques to create these latex reliefs.

 

What you will need:

Vaseline

Textural surface/Object

Latex

Latex hardener

Plastic cup

Paintbrush

 

What to do:

  • First you will need to apply a layer of vaseline to protect your textural surface and ensure that the latex can be easily removed once set.
  • Follow the instructions on the latex bottle & latex hardener and mix accordingly (usually 1 : 10).
  • Give the mixture a stir until you feel the latex stiffening.
  • Apply the latex to your surface in thin layers.
  • Wait for each layer to dry before applying the next.
  • Build to the desired thickness (I used about 4 layers).
  • When all the latex is set you can peel it way from your surface.

 

Happy Experimenting!

Experimenting with silicone rubber

Plaster casting step 3

With my plaster casts I created silicone rubber impressions.

 

What you will need:

Silicone

Catalyst

Rubber mixing bowl

Plastic spatula

Rubber gloves

Work bench

 

Here is what I did:

  • The amount of silicone you will need depends on the depth of your plaster casts.
  • Mix four heaped table spoons of silicone with one cap full of catalyst.
  • Mix well until the  viscosity of the mixture changes and becomes stiffer when stirring.
  • From arms height, drizzle the liquid into the centre of the plaster cast.
  • When you have dropped all of the mixture into the cast, give it a vigorous shake/tap to disperse the air bubbles.
  • Leave to set for a couple of days.
  • When the silicone is set you can peel it away from the plaster mould.

 

The plaster casts can be used indefinitely to create as many impressions as you like.

Happy experimenting!

Plaster casting part two

If you wish to keep the clay impressions then carefully peel them away from the plaster. The clay can be fired afterwards.

When the clay has been peeled away, you will be left with a solid impression from your clay surface.

I will be using my plaster casts to create silicone rubber impressions. To see the final step in this three part process, please view my next post on Experimenting with silicone rubber.
