Having a need for figures that will stand inside buildings that look out through windows I decided to make some using a period piece 48 year old figure from way back in the day as a pattern.
This is one method I use to make tiny tot silicone moulds using soapy warm water.
It being rather on the tiny size,i only needed a tiny bowl containing water first, then the washing up soap added.
No need for masses of bubbles unless you like them. I simple stir the water around a few times. So the hands,in this case hand is soapy wet. The soap is very important because it forms a barrier between my skin and the silicone rubber.
Squeezed into the soapy water,is just enough for my needs.
A few second and a ball is formed and with my hand as wet and soapy coated as the silicone is. It was time to fill my little moulding box containing the tiny figure.
This is the second half of a two part mould.
The first part being made by the same method. After curing it was coated with a parting agent ( Cooking Oil ) which was thinly applied by brush over the entire thing including the pattern in this case a classic figure from the Asterix Bubble Gum Range of the 1970`s. So very rare to obtain at a reasonable price these days.
It was simply thumbed and fingered into the mould and pressed lightly. As this took place the air escaped.
Using Lego bricks, a pattern,soapy water, and cheap silicone, it was and is as simple to do and use as this.
The first part of the moulding process included making an odd side out of Plaster of Paris in a Lego box,into which the pattern was inserted up to its halfway point. This odd side included small guidance holes being cut into it after the plaster was hard. After building up the Lego box further, both the plaster and pattern were coated in oil. Then the first soapy wet silicone was pressed into place filling the Lego box. Once cured the odd side was removed leaving the bottom half of the mould formed perfectly with pattern imbedded in the rubber . After Lego bricks were built up in two courses, what you have seen took place.
Simply made today I wonder what the copy of the tiny figure will look like when cast up.
I only need props for a photo shoot so Plaster of Paris will serve my needs.
And so it was that the little rubber mould costing under a Pound,was opened
It was a pleasing tidy clean halfway parting result.
She stands 32 mm in ht.
It will be poured through that tiny hole.
A Little Later
Although not a nice experience being rubber coated and Lego boxed in soapy tight she forgave me when she saw her new relations that had come to stay and play.
I cast two and then another.
There are times when I just love this hobby.
Thanks for looking guys.BB
