Glossary

  • Dip

    Dip

    A layer applied to the surface of the white jasper body using coloured slip - as opposed to a ‘solid' jasper body where the same colour permeates throughout the entire ceramic medium.

  • Black Basalt

    Black Basalt

    A fine-grained black stoneware body, composed of ball clay, calcined ochre and manganese oxide. Josiah Wedgwood developed Black Basalt in 1768 to replace the earlier ‘black Egyptian’ ware produced in Staffordshire in the mid-eighteenth century. 

     

    Basalt was described by Josiah Wedgwood as ‘A fine black Porcelain, having nearly the same properties as the Basaltes i.e., the mineral rock', resisting the Attack of Acids; being a Touch-stone to Copper, Silver and Gold, and equal in Hardness to Agate or Porphyry'. It was the result of his experiments to perfect fine-grained stoneware suitable for the production of ornamental pieces, one that would complement the neo-classical styles then coming into vogue. It is probable that Wedgwood was experimenting with a basalt body in September 1767. He wrote to Bentley, ‘I am still going on with my tryals, & want much to shew you some of them'. Certainly within 12 months Basalt was generally available. From 1773 Wedgwood's plain-black body became universally known as ‘basaltes'. Both ornamental and useful wares were produced in this versatile body and it was used to make virtually anything the public required. Wedgwood placed great confidence in his material, predicting that ‘Black is Sterling and will last for ever'.

    Black clay was derived from ‘Carr', an oxide of iron suspended in the water that had flowed through coal seams and mines. This was drained and dried and then sold by the cartload to potters for use in the production of basalt pottery. Wedgwood made no secret of his recipe for Basalt, which he recorded on page 236 of ‘Common Place Book I. The entry is dated 1777, and reads:

    ‘Our Black Basalt Body. 80 of ball clay sifted 80 of Carr [ochre] calcined & ground 9 of manganese. The above is one Blending.'

    When these ingredients were fired together at a high temperature they vitrified into a fine-textured black body. The distinctive colour of Wedgwood's Basalt, which has a deep purplish-black hue, is due to the high proportion of manganese included in the formula.

     

     

  • Engine-turning lathe

    Engine-turning lathe

    This specialist piece of equipment has an eccentric motion that enables a range of decorative, repetitive patterns to be cut into ornamental wares before firing, using a special cutting tool. Wedgwood is credited with the introduction of this piece of equipment in the ceramic industry in 1763. The technique of engine turning is a highly-skilled operation for both the turner and his assistant. Decorative patterns that can be achieved on the engine-turning lathe include fluting and dicing.

  • Rosso antico

    Rosso antico

     

    Rosso antico (literally antique red) is a stoneware ceramic body developed by Josiah Wedgwood I during the mid-to-late 1760s.  Wedgwood took his inspiration from the traditional red colour clay ware produced in the Potteries area during the 17th and 18th century.  However, he brought it to a degree of perfection not known before and utilised in the production of many decorative as well as useful items.
