Seeing therefore an easie, and compendious way of melting metals, I
began to work, and to begin a new search, and every day I found more
and more in nature, _viz._ the greatest and most pleasant secrets of
nature; wherefore I did without ceasing seek, until God had opened mine
eyes to see that which I sought a long time for in vain. Where also I
observed, that although I had before had more knowledge of nature, yet
without this furnace I could scarce have done any thing that had been
singular. And so God willing, by the help of this furnace, I found out
more and more dayly, for which blessing I give to the immortal God
immortal thanks, resolving to communicate this new invention candidly,
and faithfully for the sake of my neighbour. Judge therefore O Chymist!
whether this, or that which is made by the help of bellows and common
vents, be the best? For how long doth he that will melt a hard metal
in a wind furnace give fire to it before it will flow, and with what
loss of time, and coals? He that doth melt by the help of bellows hath
need of a companion to blow, with great danger of breaking the crucible
with the winde, and of making it fall when the coals are abated, or of
impurities falling into the crucible in case the cover thereof should
fall off, although there can be no detriment by impurities falling in,
if the matter be metallick, but not so if it be a salt or mineral,
(without which that cannot be perfected in the fire) not induring the
impurities of the coals, but boyling over by reason of them. Now our
furnace is free from this danger, because the wind comes from beneath
and crucibles come always into sight, not being so overwhelmed with
coals as in the common way, _&c._ For by this means the matter to be
melted is flowed, although the crucibles be not covered over with
coals, nor with a cover, and although thou hast not a companion to
blow, for you may at pleasure give any degree of fire by the direction
of the register. When therefore thou makest any trial in the fire have
this furnace which is recommended to thee, which build rightly with its
register for the governing of the fire, and for the drawing of wind,
and without doubt this labour shall not be in vain.
