The plaster and paper moulds made during his expeditions, at great cost, were sent to England.

Ironically, Maudslay had a hard time persuading museums to preserve his paper moulds though they now form a important records of artefacts some of which have now been lost.

In handmade papers, the pulp is hand poured ("cast") into individual paper moulds (a mesh screen stretched within a wood frame) and shaken by hand into an even layer.

Internal sizing is added to the paper pulp after rinsing and before it is cast in the paper mould; external or "tub" sizing is applied to the paper surface after the paper has dried.

Handmade papers typically have four natural deckles (feathery, uneven edges) left by the paper mould; mouldmade papers have two natural deckles along the edges of the web, and two simulated deckles produced by cutting the sheet with a jet of compressed water; machinemade papers have no deckles.
