The Straight throwing rib set of 3. Now you can make the same profile on small, medium and large pots! You save about 15% by purchasing them as a set rather than individually. One of my 4 different mug shaped ribs . The Straight gives you a solid straight up form with an indented foot. This shape is perfect for underglaze or slip transfer decorating techniques. As with all my ribs, I designed them to have a sharp angled edge so it acts a bit like a metal rib that scrapes the slip/water covered surface off your pot as you are forming the piece. They also have an inbuilt foot shape reducing the trimming your pot needs at the leather hard stage and elevates your pot off the ground, providing visual interest and a lightness to the final form. Using form ribs like this takes some practise, my best advice is to throw your pot to a similar shape of the rib and then use the rib to finesse the shape. I have found that about 500g of clay is perfect for this rib. THIS SET INCLUDES 1 of each of the below sizes. Mini: 7cm tall Standard: 10.5cm tall Maxi: 15cm tall. For left handed potters who have their wheel spinning clockwise, please select the Left handed option (LH). As will all my ribs, this tool comes with a small magnet on the back so you can store it on a magnetic tool rack – no more rooting around in drawers or tubs trying to find the tool you need!
