FURNACES for GEM TREATING RUBY-SAPPHIRE, TOURMALINE & OTHER GEMSTONES

M50P-1700

Model M50P-1700 replaces the old model M50-1700. This is the most popular model used extensively in Sri Lanka and elsewehere by professional gem treaters. This is an oversize desk-top, bottom loaded muffle furnace fully equipped with atmosphere control or vacuum; muffle tube diameter is 50 mm with load up to 1,140 carats of ruby-sapphire.

 

M80P-1700

Model M80P-1700 replaces the old model M76-1700. This is a semi-floor model This is a bottom loaded muffle furnace fully equipped with atmosphere control or vacuum; muffle tube diameter is 80 mm with load up to 3,380 carats of ruby-sapphire.

 

1200oC SPECIALTY FURNACES

Gemlab fabricates top-loading, muffle tube furnaces (mode series l VT1200 with 50 mm, 80mm diameter) intended for extended soaking (weeks, months) at maximum 1100oC with/without atmosphere control or vacuum. They are light-weight, occupying less than 50x50mm surface area consuming less than 600W at 1100oC.

 

On a given heating process, regardless the furnace model, each step of the process run may be configured to run for weeks or even months. All furnaces are energy efficient consuming minimum electric power possible. Full atmosphere control (or vacuum) can be utilized in all furnace models we fabricate and sell.

What we sell:
Like analytical instrumentation in the pharmaceutical and other industries, the users are ultimately responsible for the proper parameter setting, methodology, operation, calibration and maintenance of the equipment. An analogy in heating treating gems, we sell our furnaces like sellinga rice cooker: the user is responsible to select the type of rice, add appropriate amount of water, add various ingredients, determine the heat-up rate time, cooling time and cooling rate. Successful rice cooking is based on experiments and depends on the user, not on the equipment we fabricate and sell.

In our lab we fabricate furnaces as per specifications and limitations to carry out the heating parameters provided by the user. We do not provide recipes for heating gems, since gems are imperfect crystals having different characteristics, attributes and chemical compositions. These heating recipes must be produced by the user.

Professional gemologists
For the first time, true passionate professional gemologists will be able to gain valuable knowledge in heat-treating rubies, sapphires and other gems and study their inclusion characteristics before/after heating. This first-hand experience provides the basis of separating heated from unheated gems and their features. This is something that was never taught in any gemological institute, moreover never fully understood by most gemologists.

Gem traders
Gem traders are now able to heat-treat their own gems under their direct environment and supervision; there is no need to submit their valuable to gem treating service facilities, thus eliminating doubtful experiences, theft, switching and even loss of their gems.

Gemological laboratories
The convenience in-house gem treating facility where gems may be treated under various heating parameters in relatively short period of time provide valuable data in understanding the inclusion characteristics before/after heating and make important comparisons and building up a data bank.

High Pressure apparatus for "oiling" surface-reaching fractures

This desk-top, light weight apparatus produces maximum controllable pressure to 8,700 psi (about 600 bar) at controllable temperature 200oC. The apparatus is used to induce any type of oil, resin and oleoresin into the surface-reaching cracks of emeralds, and other beryls, rubies-sapphires and other gemstones. Most oiling applications are performed below 150 bar pressure at 60-65oC temperature.
