Hey guys and gals,
Im getting ready to start the advanced stone restoration class June 7th. Of course I am offering NSRA members a discount.
This is an online class. check it out at
Flash Intro Page.
Here is what others have said about my online classes
just want to show my gratitude to you for the information, which you have passed, to us during your recent stone restoration seminar. I have attended a training course on cleaning operators proficiency conducted by United Premas, Singapore in 2004. Mr. Tan Teong Meng of United Premas gave me your reference.
I am proud to say that I have entered in to the
marble restoration Industry 2 years ago after reading your book “How to Polish & Restore
Marble Flooring”.
After attending your recent seminar on Stone Restoration I would not hesitate to tell any of my client that I am the best in the industry with hundred percent confidences. I strongly believe that the lessons covered in the seminar starting from the geology of the stone, covering the professional and economic way of doing the job, and the marketing techniques will help me to stay in this industry forever.
With regards

Ladies and Gentlemen, Welcome to the future of stone restoration training.... online!
Mr. Hueston's new web seminars on stone restoration was what I was waiting for. Unlike most weekend seminars, I was able to sit back at an unhurried pace and actually enjoy and learn.Even better, If you miss the class or need to go over the material again, you can watch and listen to the class repeatedly via Webex. With Fred Hueston's invaluable knowledge in the field of stone restoration, the classes gave me a lot of information that would normally take years of experience to attain.His unbiased approach to products and methods was refreshing.The fact that Fred was open to answering any problems or questions even after class ended says a lot.Can't wait for the advanced classes!

 | | Marble | MARBLE: CHARACTERISTICS
This standard includes general information on the characteristics
and common uses of marble and identifies typical problems
associated with the material.
INTRODUCTION
Marble is an extremely hard, metamorphic stone composed of calcite
(CaCO3). It is formed as a result of the recrystallization of
limestone under the intense pressure and heat of geologic
processes. The effect of this process is the creation of a stone
with a very tight crystalline structure and small but definite
porosity. Because of its structure, marble can take a very high
polish and is a very popular decorative stone for architectural and
sculptural uses. The limited porosity of marble, especially
polished marble, makes it less vulnerable to the leaching effects
of water. Calcium carbonate, however, of which marble is composed,
is highly susceptible to attack by acidic agents. Marble is
readily dissolved by acids, even very dilute acids, however the
actual results of acidic exposure will vary with the nature of the
acid. Chlorides, nitrates, sulfates and other chemical compounds
react differently with marble and produce various by-products,
which have a wide range of solubility and impact on the durability
of marble. For this reason, it is always important to determine
the exact type of pollutants causing marble deterioration.
Marble itself can be of two types, one composed of calcite and the
other of dolomite. Dolomitic marble is much more resistant to acid
attack than calcite marble. The color of marble ranges from the
brilliant white of calcite to black, including blue-gray, red,
yellow and green, depending upon the mineral composition.
TYPICAL USES
Marble has many decorative and structural uses. It is used for
outdoor sculpture as well as for sculpture bases; in architecture
it is used in exterior walls and veneers, flooring, decorative
features, stairways and walkways. The way in which the stone is
used may be a factor in limiting or controlling the severity of
exposure. The use or function of the marble may also affect the
feasibility of applying certain treatments, but type of use is not
the primary factor in the major types of deterioration and damage
to which marble is susceptible. | |  |
