CONICAL PRECIPITATING GLASSES
Eight 2 fl oz Phillip's Precipitating Glasses. Michael Faraday wrote about these:
"They are of a truncated conical shape ... and are peculiarly useful in the management of precipitates, in consequence of facility with which they allow the solid matter to fall to the bottom of the liquid. The precipitate, as it descends, meets with no obstruction from the sides of the glass, tending indeed rather to shrink from it; the fluid, on the contrary, tends to rise in the space left, and thus in numerous cases great facility of separation is obtained."
M. Faraday, Chemical Manipulation (London, 1827), p. 227
