Scale?? from 1:12 to 1:6

Hi

I am terrible at maths and can not even begin to think how to resolve the
following problem, is their a simple calculation?

I bought a polymer clay 'recipe' book for making fruits and veg but the
ingredient list are to make the items in 1:12th scale:

Example: White loaf of bread
The book say I need to use:
- 25mm ball of white
- 25mm ball of beige (ecru)
- 25g texturing material (ground rice/semolina/cornmeal)

Do I just double the quantities for 1:6 scale (barbie doll size) or is it
more complex.

Sori if this is a stupid question

Also, I would to see an online tutorial for food stuffs???

Thanks again

I would have thought just double all quantities too, but then maths
was never my strong point!

But the best thing to do is to try the theory out and see if what you
make appears the right scale or not. Trust your eyes, and if Barbie
doesnt say anything, then you know you got it right g

If you are creating 3-dimensional objects, there is no easy formula on
how to convert 1:12 to 1:6 scale. It depends so much on the shape of
the object.

Simply doubling the amount of clay won't work with most things. For
flat objects that are essentially 2-D, you could quadruple the amount
of clay and that would work, but for objects where the thickness is
important, you will have to experiment. Figure about 8 times as much
clay is need.

Sure there is (unless I don't understand the question). Converting a
1:12 scale to a 1:6 scale means "doubling in all three dimensions".
Hence, you're increasing the volume by a factor of 8.

Look at it this way ... imagine a cube of size 1 cubit foot ... that is,
12 inches by 12 inches by 12 inches.

A 1:12 scale model of that cube would be a 1-inch cube. A 1:6 scale
model of the original cube would be a cube of 2-inches on each side.

THe 1:6 scale is twice (in each of the three dimensions) the size and
hence its volume is 2x2x2 as much, or 8 times.

Is this what the question was? Gee ... I've typed so much, I forget if
I'm answering this question or one on ancient Greek politics!

Oh .. I forgot to mention in my last ramble that the 8-times volume is
independent of the original shape of the object. That is, if you want to
go from a 1:12 scale to a 1:6 scale for a cube .. it's 8 times as much.
If you wanted to do that for a cone .. it's 8 times as much. If you
wanted to do it for a horse or a table or a hand ... it's 8 times as much.
