Plaster Molds 37 



table top can facilitate neat work. Rub some grease over the 

 glass so that plaster can be scraped up easily. Layers of news- 

 papers can be used or a table top can be greased. Have a waste 

 bucket handy to accommodate whatever plaster is left over in 

 the mixing bowl. If the plaster receptacles are to be cleaned in 

 the sink, be sure to remove as much plaster as possible first. 

 Then, run some water into the bowl and work the sides well 

 with a scrub brush or some rough material such as excelsior or 

 steel wool. During this process be sure the tap water is going, 

 otherwise the plaster sediment may accumulate in the sink trap 

 and stop up the drain system. I have been cleaning plaster bowls 

 in sinks for many years and have yet to experience any trouble 

 with the drainage of the sinks. However, if in doubt, or if 

 mother or the good wife frowns on this procedure, the plaster 

 bowl can be cleaned in a tub of water. And later, after pouring 

 off the water, the remaining plaster in the bottom of the tub, 

 which will not harden, may be disposed of outdoors in the trash 

 can.
