Notes
on the Soaps in the Gallery - IV Embedding
|
| General: You may wish to refer to the pages
on the Basic Method, Colours,
Fragrances and Moulds
for more details and information on suppliers. Clicking on the picture
will take you to the larger picture of the soap in the Gallery. |

| Embedding is fun and an excellent way to use up odd scraps
or soaps that didn't work out the first time. |
|
For this soap, which is not in the Gallery but which appears at
the top of the Sources page, I made up
a small quantity of transparent base and added copper mica. When it
had set up I cut it into chunks. When a second quantity of base, coloured
with titanium dioxide and a little more copper mica to make it a peach
colour had been melted I added the chunks. The copper soap in the
picture was a uniform colour before I embedded it but because the
light catches the chunks differently it has lovely gradations of colour
in the finished soap. |

Not a very successful soap but I am including this anyway. I found
an ice-cube tray in the shape of dolphins and made these first using
ultramarine blue, black oxide and white titanium dioxide. Several
failed attempts later (they fell over, they were too pale, they were
too far away from the surface to show up properly) I ended up taking
a slice off them so they would sit flat, upside down, in the bottom
of a rectangular margarine tub. I took another failed piece of very
pale blue/green soap and cut curls off it with a vegetable peeler
which I arranged around the dolphins. The overpour was coloured very
lightly with hydrated chromium oxide. You can do much better than
this. |

If you want to know where some of the failed dolphin soaps went,
here is the answer. After having surgically removed the dolphins,
the rest had a little titanium dioxide added to it and was remelted.
I had some left over scraps coloured with various micas and I used
these as chunks to embed following the basic method. The finished
result glistens beautifully when wet. |
|
|
For this soap (not in the Gallery) I made up several small quantities
of base, colouring each with FD&C pigments (the 'unnatural' ones)
to make vivid colours. Having chopped them up into tiny triangular
pieces I embedded them in a larger quantity of white base. If you
use titanium dioxide (or buy a ready-coloured opaque base) the unnatural
colours will not bleed into it. |
|
|
I first made two blocks, one of white and one of black and cut
each into blocks that were exactly the same size. I set them side
by side in alternating colours in a larger mould, wetting the sides
of each with distilled water and pushing them together so they would
stick, before overpouring with transparent base. Surprisingly it worked.

There are several methods that people advocate for embedding
and I suggest you look at tutorials on other
websites and see what works for you. What you are aiming for is
chunks that remain suspended throughout the soap and which don't either
sink to the bottom or float to the top. They need to remain distinct
but cling to the overpour. It is very depressing to cut through a
slice and have it fall to pieces. Ask me how I know. This is what
works for me (usually):
- Put the chunks in the fridge for half an hour before you are
going to use them, especially if they are small or they may melt
when they hit the warm base.
- Keep them covered and spritz/mist them very lightly with distilled
water or rubbing alcohol (I've used vodka) before adding them
to your base. Alcohol will help to disperse any bubbles that form
in between the chunks and the base.
- My current theory is that if the chunks (or other embedded
items) are damp rather than dry when you add them they will cling
better to the surrounding base and that alcohol is otherwise unnecessary.
The experiments I've done so far seem to bear this out but others
have different views.
- At this stage you have three options.
- Throw small chunks into the melted and fragranced base
in your pot, give it a stir and pour. The temperature will
reduce quickly and you need to work fairly fast to get it
into your mould if you are using a lot of cold material; or
- Pour a layer of base into your mould, let it cool slightly,
place a chunk in it to see whether it will support it, add
a few more chunks, add another layer of base, wait, add more
chunks, and so on; or
- Place your chunks or other material in the mould and pour
your base carefully over it.
