I was looking for a 'blob' of resin/cement.

Galt Modeling Clay - cheap, air dries, grey only I think.

Fimo Modeling Clay - cheap, needs to be low temperature baked, range
of colours.

Both available from many places mail order, the Galt might be found
in toy shops. The Fimo more likley in craft places.
