We've just spent some rather valuable (ie we shoulda bin doing
worldcon stuff) time searching for our copy of the hectograph recipe
described below. Luckily, a friend had a copy she picked up off the
net and was able to rescue us.

I'm reposting this so that a) more people can have the fun of trying
it out and b) we can perhaps grab a copy off a web page or ftp site if
we ever lose it again...

Turkish Delight Duplicator Recipe

Copyleft Steve & Jenny Glover, 1993,1995

We still use a "Turkish Delight" duplicator for small print run stuff
(apa contribs, small con newsletters of the informal persuasion) and
security printing (Postscript output -> ghostscript -> 9 pin printer ->
coloured Banda paper --> unduplicatable tickets for whisky tastings
etc).

Anyway, here's Jenny's recipe (as obtained from a friend of a friend of
a 'freedom fighter' who apparently used to run across the veldt
duplicating leaflets with one hand and scattering them with another ...)

You will need.

1 large roasting tray, big enough for a sheet of paper. This is going to
be the 'bed'.

Sheets of good quality typing paper (laser printer or photocopying paper
will do quite well) for the master copies

"Spirit Duplicator" carbons (one UK trade name is 'Banda'). Ordinary
carbon paper will not do. These sheets come in a range of colours, but
purple seems to be traditional. You prepare your master by typing or
printing (with an impact printer, not a laser or inkjet!) so that the
carbon material comes off onto your master sheet.

Preparing the 'bed'.

[This recipe uses gelatin, which *can* be produced from non-animal
sources, but which usually isn't. Somewhere we have an equivalent recipe
that uses carrageenin gel or agar agar, but you will have to work these
ones out for yourself by trial and error, as we're not so practised with
these ones]

In a large saucepan dissolve 100g gelatin in 375ml water then begin to
warm it gently while adding 385g of sugar. When it has dissolved, add
715g glycerol and slowly bring the mixture to the boil. Stir gently for
one minute while boiling to avert the wrath of the Foam Ghods.

Remove the mixture from the heat and pour it slowly into your tray
(care! this mixture boils at a higher temperature than water -- for the
purposes of rug rats and house apes, treat it as molten fat).

Make sure that the tray is on a flat surface where it can be left for a
few hours until the gel sets.

While the gel is cooling, the Foam Ghods can be further appeased by
using tissue paper to remove bubbles, foam and 'bits' from the surface.

Using the duplicator. 

First, moisten the surface of the bed by swirling cold water across it
and wiping it dry with a fine sponge. There should be no droplets of
water left at this point.

Take your master copy and lay it face down on the gel, smoothing it down
with the back of a spoon (or by hand), taking care to avoid bubbles and
areas that are not in contact with the surface.

Leave it there for a few minutes to allow the ink to transfer into the
top of the gelatin (care: the longer you leave it, the deeper the ink
goes, so the more copies you can make, but if the surface was too wet,
you run the risk of incurring the wrath of the Dhemons of Diffusion).

Remove the master carefully (it may be re-usable, depending on how many
copies you need) -- if it tears, never mind, the surface was too dry
anyway.

Take a sheet of ordinary paper and slowly smooth it down over the right
part of the bed. Peel it back, and step back in amazement! It works!!

Repeat 30-50 times, omitting the step back in amazement as the miracle
becomes mundane. If you want more copies clean the surface (see below)
and replace the master.

Cleaning the Surface.

Cover the surface briefly with warm water. This will dissolve the ink
(huzzah!!) but also some of the surface (boo! hiss!) so swirl it away
quickly while using a separate fine sponge (which will soon become a
fine fhannish shade of purple -- and not one you would want to use to do
your sensitive fhannish face with) to remove the ink. Wash the surface
with COLD water to help reset the gelatine, dry the surface again, and
use a sheet of white paper to check for any leftover ink on the surface
(ink below the surface isn't often a problem). be careful not to damage
the smoothness of the surface.

Damage Control. 

If you do damage the surface, all is not lost. Simply (if you are using
a metal tray only) remelt the surface and let it re-form, obeying the
imprecations and instructions above re: the propitiation of the Foam
Ghods.

For serious damage, remove the gel from the tray, and redissolve in a
*little* boiling water, bring back to boil as above and continue with
the procedure as appropriate.
