The acid etching or satina process is the removal of silisyum particles from the surface of glass using acid. In this way microscopic cavities occur on the glass surface and due to the refraction occurring in different directions our eyes perceive the glass to be white.
It's greatest advantage against sanded glass is that it does not allow fingerprints and that it's cleaning is much easier. It has a much finer surface compared to sanded glass.
â??
Our satina products are usually used in the interior decoration and furniture sectors. We can process clear float, extra clear, tinted ,reflective glasses and mirrors as a satina glass.
Our satina products can be tempered, curved , and laminated.
Laser Reflection and Refraction Tank demonstrates the principle of reflection and refraction. The clear circular acrylic tank has a circular scale graduated on the white base of the tank, making it easy to measure angles. Adjust the pivot-arm mounted laser to any angle along with its full 360�° range and measure the angle of reflection or refraction. Rotate the laser and observe first a reflected ray, then both a reflected and refracted ray, and finally just a refracted ray. Leveling screws on the tank's base make leveling quick and easy. The laser is attached to the pivot-arm by a magnet and can be removed for use in other experiments. Instructions included.
Supplier: Water and weatherproof workwear made with pvc and polyester fabrics (one piece, two pieces, reinforced, poncho type, translucent, with braces), aprons, beekeeper vests, etc.

TRANSPARENT GAUGE GLASS
These work on the principle of difference in reflective indices of liquid in the tank and possible presence of gas with the liquid. The liquid will be black display while the gas or vapor will be white display.
These level gauges have glass etched with reflecting prisms at inner surface. This surface reflect the light falling on the surface and enable detection of surface of even colourless liquids.
Operating Principal: The Principall of the Transparent Guage Glass is based on the difference in the refractive indices of liquid and gas or in particular of water and steam. It has prismatic right angled grooves,on the side facing media.if a ray of light encounters the surface of one of the 450C slanted grooves in the gas or steam space it is reflected to the opposite surface of the groov and from there totally refiected back into the direction of observation The steam or gas space therefore appears as silver - white
The light ray which encounters the surface of a groove in the liquied space is almost totally absorbed.The liquid behind the reflex glass therefore apperars black. Light rays entering from outside the gauge are either absorbed or reflected depending opon whether they enter the water or steam space
(Serveral sizes are available in both Transparent Gauge Glass & Reflex Gauge Glass)
