What is this all about?


          Pyrometric cones are small clay-like devices, shaped in the
     form of a triangular pyramid, which are used to guage the
     heat-treating process when firing ceramic and pottery objects in a
     kiln (furnace).  Cones are available in a numbered series to
     provide for differing degrees of firing, and simply melt and slump
     when subjected to the degree of heat (time and temperature) which
     corresponds to their particular number, thereby giving a visual
     indication that the firing process has been completed.

          The various types of commercially available clay and glaze are
     ordinarily provided with firing instructions expressed in terms of
     cone numbers ("For best results, fire to Cone 6 in a slow kiln.").

          In order to use modern temperature controllers for the firing
     of ceramics and pottery, it is necessary to convert these
     instructions to practical controller settings ... "fire to 2250F at
     a rate of 270F/Hour.  This file contains charts in F and C which
     give the time vs temperature information for each standard
     pyrometric cone, as determined by the National Bureau of Standards
     (now the NSA).

Installation and Use


          This is a Windows 3.1+ HELP (.HLP format) file.  It may be
     installed in any directory or, if you wish, you may install it in
     your c:\windows directory where all your other Windows .hlp files
     will be found.

          To use this file, open the file manager and double-click on
     it. Files with the .hlp extension are normally associated with
     winhelp.exe, which is ordinarily found in your c:\windows
     directory.  If double-clicking on the pyrocone.hlp filename does
     not pop up the help file, you need to click on FILE, ASSOCIATE,
     BROWSE and select winhelp.exe from the c:\windows directory.

          For the greatest convenience, copy the pyrocone.ico icon which
     accompanies this file to one of your Program Manager groups to pop
     up this file with a click of your mouse.  To do this ...

          1.   select the group you wish to use
          2.   click on FILE, NEW, PROGRAM ITEM, OK ...
          3.     Description = Cones! (or your choice)
          4.     Command Line = c:\windows\pyrocone.hlp  (*)
          5.     Working Directory = (blank)
          6.     Shortcut Key = (blank)
          7.   then click on "Change Icon ..." and enter
                 File Name = c:\windows\pyrocone.ico  (*)
          8.   click on "OK" twice to save this setup and return
                 to the Program Manager.
          9.   click on the icon
