IV. MAINTENANCE. Cultures should be examined daily, observing the morphology, the color of the medium and the density of the cells. A tissue culture log should be maintained that is separate from your regular laboratory notebook.
A fire pit is an open burning bowl, whereas a chiminea is built with a chimney. The outdoor fireplace products on the market that have mesh wrap-arounds, multi openings or bowl designs should be considered fire pits.There are many fire pits incorrectly advertised as chimineas, but they are not chimineas.A chiminea will have a flue or chimney that drafts properly much like an indoor fireplace. The drafting on a chiminea naturally brings fresh air into the fire and directs smoke up, away from guests. cast iron or cast aluminum chiminea is always going to be a better investment that will last many years after a clay one falls apart. The majority of clay fireplaces have a life span of less then a year before needing to be replaced. We recommend metal chimineas to anyone considering purchasing a chiminea.
Some people opt for a chiminea. This is a stand-alone fireplace with a conical shape topped by a chimney. Made of metal or clay, they cost between $50.00 and $500.00. They stand around 5 feet high and are around 2 feet wide.
