A Clean and dry the density bottle and weigh it along with the stopper W1 in gB Select about 25 gm of dry soil free of clods and put the same into the density bottleWeigh it with brass cap and washer W2 in gC Fill the density bottle with deaired water up to half its height and stir the mix with a glass rod.

At their most basic laboratory ovens can also be used to sterilise lab equipment and glasswareCarried out in a hot air oven the ideal temperature needs to be at least 160C with contents monitored at this heat for 45 to 60 minutesA slow cooling period is needed as removing items from the oven straight away can cause them to crack.

Keep the oven door slightly ajar and run the exhaust over the stove to remove any baking odors from the kitchenFlip the sand over if it is still wet on the bottomLet the underside bake about a half hour or as long as needed to dry itWhen dry let cool and pour the sand into individual containers based on color.
