Oxy-propane torch

[Martin H Ray <mhray1@zzzzzzzz>]

Greetings, Kent Lee Ivey,

You have mentioned a couple of specialties in your background which might
enable you to advise me on these questions:

1) What sort of cutting torch adaptation or equipment do I need to work
with an oxy-propane rig for thermal surfacing of granite?

2) I recently made an in-ground mosaic partly of tinted cement/coarse
sand mix at a 1:3 ratio, poured and cured in molds then set in stone
dust. Any suggestions on altering the process for maximum strength and
longevity?

Martin
