Bricks should be dry before use. The wall gains strength when the mortar penetrates the pores in brick and block construction. This is the reason that blocks in an engineered block wall cannot be reused once installed.
because if not wetted,
bricks will absorb moisture in motar
The bricks should be wetted so the bricks do not suck the moisture out of the plaster and allow it to dry to fast and then flake off.
You can use an old bricks if you have some before or you can buy some old bricks from the internet. You can make it beautiful depending on your design.
The following visual tests and field tests be carried out to ascertain good quality bricks for use in works. a. Well burnt bricks are copper colored and are free from cracks. b. They posses sharp and square edges. c. They are of uniform color, shape and size as per standard. d. When struck with each other, they produce clear metallic ringing sound. e. Fracture of good bricks show uniform and bright compact structure without any voids. f. They absorb minimum water when immersed in water. The absorption should not be more than 20 % when immersed in water for 24 hours. g. Good bricks are hard on their surface and leave no impression when scratched with nails. h. Good bricks do not break when dropped from 1 m height i. Good bricks when soaked in water and dried, do not show white patches or white deposits on their surface. j. The good quality bricks could be gauged easily by the percentage of bricks that get broken in transit and stacking in the course of ordinary handling (2 to 3%).
The Sumerians used mud bricks to build their houses. These bricks were made by mixing mud, water, and straw, and then drying them in the sun. The bricks were then stacked and bound together with mud mortar to construct their homes.
Due to high strength, practically no breakage during transport and use.Due to uniform size of bricks mortar required for joints and plaster reduces almost by 50%.Due to lower water penetration seepage of water through bricks is considerably reduced.gypsum plaster can be directly applied on these bricks without a backing coat of lime plaster.These bricks do not require soaking in water for 24 hours. Sprinkling of water before use is enough.DisadvantagesMechanical bonding strength is weak. But this can be rectified by adding marble waste.Limitation of size. Only modular size can be produced. Large size will have more breakages.
yes, they should be soaked over night
Wood float on water, bricks not.
Linen cloth, or sponges soaked with water, wine, oil or vinegar.
The Sumerians used baked mud bricks to construct their ziggurats. These bricks were made from clay mixed with water, shaped, and then baked in the sun or a kiln to harden. The ziggurats were then built by stacking these bricks on top of each other.

You can use a milk container filled with water to weight it down so it doesn't float. You can put one or two bricks in the tank.
water bucket, automatic water dispenser, soaked hay, stream if outside. If you want to get it to drink use salt licks or electrosalts
Indus Valley bricks were made by mixing clay with water to form a paste, then molding the paste into brick shapes and leaving them to dry in the sun. Once dried, the bricks were fired in a kiln to harden and strengthen them for use in construction.
