Start by rolling out a slab of clay that is about 3/8ths of an inch thick and large enough to accommodate a rectangular paper template that is about 4" x 10" ( you can always make yours smaller or larger as desired!). Cut out the rectangle and form it into a cylinder, scratch-to-attach the edges together and smooth the seam. Then place the cylinder on top of a slab of clay and trace around it to create the right size circle for the bottom then scratch-to-attach it on well. Now using a paper template for the spout, which is basically a triangle with the bottom side rounded outward, cut out the spout, curve it and scratch-to-attach it onto the side of the cylinder. Then cut away the part of the cylinder where the spout is attached and smooth out the throat of the spout so that it is continuous and the liquid won't hit any bumps on its way out. Make sure to keep the lip of the spout straight edged on the end or your liquids will drip down the sides when you pour. Next cut out a long and thin rectangle that you'll use for the handle, it will need to be about an inch and a half wide by about 8 inches long (if its too long, you can always trim it). Bend the rectangle into a half heart shape and scratch-to-attach it on opposite the spout. Now you can decorate your slab built pouring vessel however you like, let it dry and bisque fire it. Be sure to glaze the entire surface to keep it sealed for liquids, fire it and then see if its functional!
