Frequently Asked Questions

I bought a glass sink from a different manufacturer and it cracked.  Why should I buy another glass sink?

JSG Oceana's unique "hard roc glass" is our own formulation of borosilicate glass.  Superior to soda lime glass sinks from other manufacturers, our hard roc glass sink is scratch resistant, stain resistant, thermal shock resistant.  Our sinks stand up to everyday use including changes in temperature.  Watch our video (Broadband Dial Up) to learn more.

Which is more durable and functional, JSG Oceana’s “Hard Roc” borosilicate glass or traditional soda lime glass?

The most common type of glass sink and the cheapest to make is soda-lime glass. Soda-lime is among the highest expansion ratios of any glass giving it poor resistance to high and sudden temperature changes. Additionally, soda-lime glass has only fair resistance to chemical corrosives. Tempering can improve the temperature and impact resistance of soda-lime if the glass is true tempered. Glass products made in foreign countries may not be tempered properly causing the product to become brittle and subject to cracking or chipping.

ALL "JSG OCEANA SINKS AND TILE ARE MADE OF JSG OCEANA “HARD ROC” GLASS a unique formulation of BOROSILICATE GLASS created by Jeannette Specialty Glass. Borosilicate glass is the oldest glass to show high resistance to sudden temperature changes. In fact, borosilicate is the glass of choice for refrigerator to oven cookware. JSG Oceana sinks and tile can withstand repeated temperature changes between 0° and 212° F without damage. Unlike soft soda lime, Borosilicate is highly resistant to chemical corrosives and can be cleaned with any commonly used household or commercial strength product. JSG Oceana glass therefore will NOT become cloudy or rust marked over time. Borosilicate glass is both stain and stretch resistant.

If borosilicate glass is more expensive to use, then why is soda lime glass so much more expensive to buy?

Aside from the complex artistic enhancements that can be applied to either soda-lime or borosilicate glass, the key difference is in the ability to manufacture in volume. Borosilicate glass is molten to 4000° and pored into a mold then pressed. JSG Oceana pours 40,000 lbs of glass per day, enabling us to produce 700 or more sinks per day. Soda-lime glass is heated and bent, manipulated by hand rather than formed in a modern factory process. With this older method, production is generally limited to 10-20 sinks per day. Increased volume allows JSG OCEANA to offer a more expensive product at a more reasonable price.

What are the small particles inside of my JSG Oceana Glass sink?

JSG Oceana sinks are made from a borosilicate glass. Crystallized glass is part of the natural art process of borosilicate production and a common contribution to the aesthetic value of JSG Oceana sinks.

Why is there a color variation within the same size and color sink?

JSG Oceana “Hard Roc” glass formulation is an art. The coloration process is hand applied giving each piece a distinct uniqueness that will compliment any decor and magnify the beauty of its environment. The color variation is most pronounced in our blue reflection and gold reflection sinks. When multiple sinks of the same colorations are ordered at the same time every effort is made to choose like sinks. Because the process is not completely automated, but continues to rely on the design expertise of our glass engineers, exact colorations cannot be guaranteed.

Is the color painted on the sinks?

No. JSG Oceana glass is a liquid borosilicate glass formulation poured into a mold. The coloration is then hand-applied to each individual sink, fusing the color to the glass at temperatures above 1000°.

What is the difference between the colors Copper and Cobalt Copper?

Both Cobalt Copper and Copper are the same coloration. However, the way the human eye responds to color in glass is dependent on the way the glass is displayed and its exposure to light. When a copper vessel is installed above the counter, more light goes through the vessel. A deep blue color radiates when light shines through our JSG Oceana Copper, hence “Cobalt Copper.” The same occurs when light is placed behind the drop ins and undermounts, but rarely is a light source installed inside of your bathroom cabinet, so it is more appropriate to call the coloration “Copper” when used with these products.

Why do Green Reflections and Gold Reflections not come in Undermounts?

Green Reflections is called Brown Reflections in an undermount as Gold Reflections is called Sunset in an undermount (you will note their item numbers are the same). The shape of the sink determines the coloration. When Green Reflections is fused into an undermount, the vessel, rim area especially, becomes a darker and deeper green, nearly brown. With the Gold Reflections, the vessel, rim area especially, becomes a deeper red and orange mixture.

Is hardware included for installing your sinks?

We do not include hardware for the installation of an Undermount sink because the hardware required (nails or screws) are dependent upon the countertop (i.e. wood, marble, ceramic, etc.). Hardware for JSG Oceana sinks can be purchased at any hardware store. The Undermount is installed with L brackets and the appropriate screws.

Does JSG Oceana supply templates for the basins?

JSG Oceana supplies templates for the undermount, drop-in, and kitchen sinks. Upon receipt of your sink the template, installation instructions, and care and cleaning instructions can be found inside the box.

Do I need a mounting ring for my JSG Oceana glass vessel sink?

No a mounting ring is not required for JSG Oceana vessels because they sit flat on any surface. JSG Oceana “Hard Roc” glass is in liquid form as it is poured into a mould, because the mould gives the shape to the glass sink the sink sits on your counter without rocking. Soda-lime glass sinks are slumped causing them to have an uneven bottom which requires mounting ring for them to sit flat on the counter.

Does JSG Oceana take special orders?

JSG Oceana works through its dealers to provide customization of drain and faucet holes on certain orders. Because JSG Oceana Glass manufactures its “Hard Roc” glass using modern, factory oriented production techniques, we do not take special mix colorations or uniquely sized and shaped sinks, etc. However, we do offer a wide range of products and colors, and it is our uniquely modern production system which brings our premium home glass decor products to the marketplace at such reasonable prices.
