I would like to collect hot dripping candle  wax (or melted wax) into hot
water.  Then, I would like to maintain the melted wax in liquid state.
Could someone suggest

One of my friends recently bought a hyperbaric oxygen
chamber which utilizes a "oxygen concentrator" to provide
a greater than atmospheric oxygen concentration within the
chamber. Does anyone on this newgroup know how such a

How abrasive is calcium carbonate.  When I encounter it as chalk it
seems only very mildly abrasive although I might not even go as far
as to quite call it "abrasive"!
Calcium carbonate is sometimes use in some toothpastes but hydrated
