I believe sodium silicate is an effective adhesive for soapstone
AKA Waterglass.

Thanks Steve: Will try.
Would never have thought of that. The only mention I seem to
recall about 'Waterglass' is that it was used circa W.W.II to
coat whole uncooked eggs in shell, to preserve them!
Or am I confusing it perhaps with something called 'Isinglass'?
Regards Terry.

Thats the stuff - you can probably get it from a good chemist.

That is some part of a sturgeon I think ? Contents of its swim bladder ?
Used for clarifying wine and beer.

Right on Steve. Thanks. My daughter is a home wine maker and I
think that's what she has used; called 'Fines' or 'Finings' or
something.
Must go and see Keith our friendly 'Pharmacist' at our local
'Drug Store'. (Americanized here in Canada!)
So not only the caviar of the sturgeon is used, eh?
Best regards and thanks for the replies. Terry.

Isinglass is mica.

Just to keep things straight, "isinglass" is the mineral muscovite AKA
"mica". Muscovite is translucent and splits easily into thin layers;
said layers used to be used in things like wood/coal burning stoves in
the door so you could see inside without opening the door.

Thanks Paul. Unfortunately the new pieces are going to be very
small; I'm only an amateur repairer and drilling and pinning may
be beyond my ability: but you never know! That's a good
suggestion thanks.
It was the slippery (almost oily) nature of the talc-stone that
caused me to post my enquiry about the most suitable glue to use!
Maybe however a 'poor bond' might be an advantage. If I do a
botch up job of repairing it might be that much easier to get my
poorly made pieces off again. I have no delusions or concerns
about the value of this piece; but it is a nice little carving of
an Esquimaux figure in a Kayak, made in Pangirtung northern
Canada in a sort of greenish soap stone, which I literally picked
up at a dump site. Why anybody would want to treat it that way I
can't imagine! So it's been on one end of the work bench for some
30 years now as one of those d-i-y jobs "I must get at some
time!". And between my son and I we seem to now have the bench
drill, Dremel (Rotozip) tools etc. that would facilitate it.
Many thanks again to all who have replied. Cos it is stretching
the home repair or d-i-y a bit?
More along the lines of 'Carving' or 'Model Making'!
Oh; btw I heard someone mention that soap-stone can be/is used
for counter tops!

Remember?

"The wheels are yellow, the upholstery's brown,
the dashboard's gen-u-ine leather...
with isinglass curtains you can pull right down,
in case there is a change in the weather!"

Woodworkers can drill a hole for a dowel in one piece yhen plug it with a piece
of metal with a sharp point, press the two pieces to be dowelled together and
there is a mark where the second hole needs to be. Maybe a crayon?
