The refrigerator should be large enough and should be lined with galvanized iron heavy enough to withstand the greatest amount of wear. The use of imitation porcelain lining instead of the opalescent white glass, or white tile, is bad practice, as the former, which is cheap metal lightly coated with porcelain, will rust in a short time, and become unsanitary. The use of light-weight glass is also improper, as it becomes easily broken and is therefore costly to maintain. The use of heavy brass hardware, both for hinges and catches, is desirable, as the hardest kind of wear is given them.
