24 Feb Slab Building Exercise – box bottle Posted at 20:39h in Uncategorized, workshop by Elaine Bolt Ceramics For this exercise I have used a smooth stoneware clay and made mitred joints to make the box shaped bottle roll out a clay slab using guides for thicknesscompress the surface using a kidney or card and leave the slab to go leather hardmake a template using cardboard to cut out pieces to construct a boxonce the slab is leather hard, cut out your box walls using the template – you will need six pieces – one for each side of the boxuse a mitre tool to make angled edges on the wall piecesOR use a potter’s knife to cut an angleangle the edges on all your piecesscore all the edges and before joining, use water or slurry on the scored edges to join the sidesjoin the walls to the base, supporting if necessary – you can use a straight edge of a box to support it. Avoid making dents in the now soft edges of the box use a brush to smooth away any slurry and firm the joins on the insideto make the neck of the bottle, roll out a sausage (or you can coil, slab build or throw a bottle neck.flaten out the clay slightlyuse a dowel to make an indent across the middle, then cut along one of the long edges to make a flat edge, leaving the other edge roundedroll the piece into a tube with the rounded edge at the topcut off excess clay where the ends overlap to make the neck the right sizejoin the tube ends to finish the neck. Leave to go cheese-hard, or leather-hard before joining to the slab topmake a cross to find the centre of the top side and mark where the neck hole will gomake a hole then add the neck to the top slab by scoring and slipping. Do this before adding the top slab to the box. This means you can firm the neck on to the top without distorting the newly constructed boxOnce you’ve joined the top slab and neck part to the rest of the box, the bottle is finished. Tidy the joins once the edges have firmed up a bit.When the bottle shape has been tidied up, decorate the pot as you likeHere I have added slip to decorate and made marks / painted over seed heads to make a design
