An empty crucible was placed on a scale and weighed. Unknown hydrate was then added to the crucible.The crucible was once again weighed to calculate the mass of the unknown hydrate. The clamp was placed close to the fire and a triangle was placed on top to hold up the crucible. The crucible was allowed to sit above the flame until there was no more water vapor left in the hydrate. Tongs were used to remove the crucible and it was cooled for 5 minutes. Observations were written down about what the hydrate did as it changed into an anhydrate and how it looked after the water was gone. After the anhydrate cooled, the mass was retaken. The mass of the crucible and anhydrate was subtracted from the crucible with hydrate to find the new mass. The new mass of the anhydrate was subtracted from the hydrate and this was the mass of water lost. This number was then divided by the mass of the crucible with hydrate and multiplied by 100 to give the percent mass of water. Using the masses of 4 known possible hydrates, the identity was inferred.
