Graduated Cylinder - 250 ml.
 
Impact resistant plastic. Graduated Cylinders are used to measure the specific gravity of slip. Specific Gravity is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water. Source: Wikipedia. Most ceramic slips have a density of around 1.75, with a range of 1.72-1.8. To measure, pour in 250 ml. of slip and weigh. Then clean the cylinder and fill with 250 ml. of water. 250 ml. of water should weigh 250 grams. At 1.75, the slip will probably weigh around 438 grams. If you divide the slip weight(438 grams) by the water(250 grams), you come up with a specific gravity of 1.75. If the specific gravity is around 1.72, you have too much water in your slip. Excessive water can cause excessive shrinking and cracking of the slip wall. Net Wt. is .25 lbs.
