This was made by a tin-glaze process[2] (dip, dry, paint, fire), resulting in an opaque white glazed surface decorated with brush-painting in metal oxide enamel colour(s).
This type of majolica was introduced to the public at the 1851 Great Exhibition in London, later widely copied and mass-produced.
Leon Arnoux, the artistic and technical director of Mintons, wrote in 1852, "We understand by majolica a pottery formed of a calcareous clay gently fired, and covered with an opaque enamel composed of sand, lead, and tin...".
[5] Arnoux was describing the Minton & Co. tin-glazed product made in imitation of Italian maiolica both in process and in styles.
Minton's designs for Palissy ware, also known as majolica, were suited for 'thick' painting of coloured lead glazes onto surfaces moulded in relief to make best use of the intaglio effect.
The science involved in the development of multiple temperature compatible coloured lead glazes was complex, but the process itself was simple (paint, fire).
[14] This majolica is the vibrantly coloured, frequently naturalistic style of earthenware developed and named Palissy ware by Minton & Co. and introduced to the public at the 1851 Great Exhibition that was mass-produced throughout Europe and America and is widely available.
[16] Tin-glazed earthenware having an opaque white glaze with painted overglaze decoration of metal oxide enamel colour(s) is known as maiolica.
In France, Germany, Italy, Spain, Mexico and Portugal, tin-glazed wares are called maiolique, majolika, maiolica, mayólica, talavera, and majólica respectively.
