New evidence of the production of skylights in the Vinalopó valley: a mould from Villa Petraria (Petrer, Alicante).

We present a mould or negative, corresponding to the upper half, which would have been used to produce disc-shaped skylights of the Dressel 18 or 19 type. It comes from the Villa Petraria pottery complex (Petrer) where the production of construction material has also been documented.
