3-5mm thick is my aim.This will make it a lot easier to break pieces up while modelling in order to go with the flow of reshaping where it is felt necessary. i set upon an idea that would include 9 heaped Table Spoonfuls of Plaster of Paris,3 small Yogurt pots each filled with water tipped in from two measurements from their small cup section.A stretch of Cooking Foil was extended and this was loosely crumpled up in shape hopefully creating what i needed,but it was trial and error. Lumps of coal one could buy years ago are now a distant thing of the past,but would be perfect once washed,then dry brushed with paint. Or used for patterns for making rubber moulds.
Rubber Latex Moulds are very expensive but produce great castings,but i grudge paying out good money on something i would only use on a small scale.If one is modelling part of the Grand Canyon they would be a good investment,but i aint.
3 Spoonfuls of Plaster of Paris into each and just mixed up with a large cheap brush.
The trick is not to lump it on in one big pour,but gradually as described below.
I painted the first layer on and left it to go off and harden.
Then did the same with another two layers.
The other castings are for Sci Fi & Fantasy projects.
The shinny stuff pealed off Perfectly.
This piece measures just over 1 Foot by 9 inches ,and cost only a few pennies to produce.
In a couple of days it will be very light and perfect for sticking into place on the canal project with Silicone Sealant.
Its playful Beano Boy Fun!
Yes very thin,and very very cheap. For a first attempt i am pleased,but like when at school,on the report card,"Could Do Better i think applies."
i re-used the metal foil and the second one is nearing its finish too,and each one is unique.
i wonder if my rock climbers will like scaling these rock faces.
Ones own imagination can easily come into play but do remember not to over crimp it because you`ll end up trying to pic shinny stuff out of the rock in places like those old 49` ers BB
The 2nd Casting Using The Same Foil
Yah! i`m well pleased and both Shell Castings are 3mm Thick.
Thanks 4 Looking BB
