Flint and super-flint are expressions for bottle glass qualities. Flint has good transparency, while super-flint offers the very best in clarity, often compared to crystal. Super-flint bottles tend to be of more substance, heavier, and often contain a deep base - 20-30mm - that gives the bottle a further feel of quality. Super-flint tends to be the choice of brands in the premium spirits sector, particularly those in the Vodka, Cognac, Brandy and Whisky categories.
As a feature to the mould itself, it is no problem to incorporate embossed/de-bossed features in your bottle. This is a cost effective (free) way to give your product more impact and individualize your brand. Not all detail can be achieved this way, but send us your design for review and we can let you know.
There are numerous types of decoration available to further customise the design of a bottle:Ceramic heat transfer printing: a method of applying a decal to the bottle that is then baked onto the surface of the glass. The cost of the label generally depends on the number of colours and its size.
For decorative patterns, see-through windows or as an overall treatment.
Full, partial or graduated coloration that is applied via a fine organic (food-safe) spray which is then baked “externally“ onto the surface of the glass. We have a portfolio of colours available or specific colours can be achieved through matching against a sample, or pantone colour. Colour can also be added into the glass material itself during production. Although many colours of glass are achievable in this way, clients may be somewhat at the disposal of the production schedule awaiting a run of a campaign of their desired colour.
Ancillary décor: metal badges, wood, plastic, wax, diamante crystals and other embossing and de-bossing.
We work with all our clients in the strictest of confidential as a matter of course. Those that wish us to sign a confidentiality agreement to this effect; we are willing to do so. This tends to be a pre-requisite for some of the larger firms that work with us.
The client is the owner of the mould and as part of our terms of service we cannot use the mould for any other customers. Clients are at liberty to “port” the mould to any other factory, or take it back after completion of the production, if they wish to do so.
We will not make another bottle that imitates your design. It belongs to you and we will respect this. We are a foreign company and operate with business practises and ethics accordingly.
Minimum Order Quantities (M.O.Q. ) varies with size of the bottle and glass type
In general here are our MOQs:
We are offering flint glass quality with tiny defects, appropriate where clients are attempting to achieve an antique or artisan style, with an MOQ of 8,000 bottles. Vintage glass bottles are becoming very popular. We have set up a new production line specialized in these vintage style bottles.
A sample mould can be used as a phase of a client’s bottle-development process. It is a cost effective way for a client to review their design and make adjustments to it before committing to full production. A sample mould is only good for about 5-10 sample pieces.
A production mould is fabricated only when the final design has been confirmed. This is a full-set of production moulds, and depending on the size of the bank, good for around 500,000 pieces. In the event that a mass production moulds expires, either during or after its design-life, Rockwood will replace it free of charge.
There is an alternative/preliminary solution to making a full-working prototype in glass. For $450.00 - and with an approximate 10 day lead time, it is possible to make an acrylic model. This is a solid piece of plastic acrylic, not operational as a bottle, but does provide a representation of the external shape of the design.

Rockwood China ensures high-quality output of bottles through a multi-tiered rigorous QC process. Post annealing inspectors are placed to observe for inconsistencies, imperfections & occlusions. Glass bottles are then subjected to machine inspection, and finally a secondary physical inspection. Machines are also initially calibrated such that that bottle volume and dimensional tolerances are within acceptable standards. In the event that you have a specific inspection criteria, Rockwood can formulate a bespoke process according to your criteria. Additionally clients are welcomed to visit and inspect the glass factory in China. This can be facilitated via your account manager.
Concerning quality-related matters, references from our existing clients are available on request.
We are used to working with a numerous companies, both small and large, from all around the world and are sensitive to each individual client’s needs. We are happy to adapt accordingly and where required welcome inspectors/technicians at the glass plant in China to oversee production.
China, rightly or wrongly carries a notorious reputation about its quality. Faced with this scepticism it is Rockwood’s China belief that they need to exceed the quality of their western counterparts to allay people’s concerns. We have years of experience and numerous qualified personnel that understand the risks and quality pitfalls, and how to mitigate them in China.
In the event that external assurances are required for our clients, SGS, TuV or Bureau Veritas (all with offices in Shanghai) can be appointed as a 3-rd party testing institute.These companies can provide in-line inspection, final random inspections (pre-shipment) and additionally test your glass bottles off-site in laboratories if necessary.
We have two glass plants. The first one is located south of Shanghai, while the other is north of the city, approximately 1 hour by plane. These two plants are at a close proximity to our Shanghai Design/Marketing office. If you wish to visit our factories before committing with Rockwood, please contact your account manager to arrange.
Rockwood is a company that strives to ensure that the client gets what they really want. We don’t expect clients to be familiar with 3D CAD software, nor wish to pay for hugely expensive marketing or industrial design companies to help with the design elements of their new product.
Our marketing and design team is international and multi-lingual in Chinese, English as well as French, Spanish and Tagalog.
We have extensive experience in working together with customers and helping them achieve their vision on paper before making it into a reality. We also know where the engineering-limits are to working in glass bottle in China and can guide you to a design that is actually achievable in mass production.
The design of your glass bottles is principally provided by you, the client, although during the course of the process Rockwood may have had some influence over the design from an engineering perspective. Open channels of communication are important during the development of the packaging. It is a collaborative process that requires input from both sides to achieve the right look as well as being producible. It is also important that your bottle is engineered such that it is not prone to any wall-thickness deficiencies, or stress concentrations. We should be able to produce a design-sketch within around 10 days from the finalisation of the brief.
On approval of the design-sketch we are able to transpose this design into a final technical drawing. This will then be passed back to the client as a process of approval. With this bottle drawing approved, we are then in a position to progress to making a sample-mould or full set of production moulds. In the event that you have identified a glass bottle that you like the look of, or is the inspiration behind your own vision for a glass bottle, we can help you navigate towards a design that sufficiently deviates from an existing design to circumvent any possible IP infringement. Further to this, the above development process applies.
Yes, of course. Rockwood gives you the opportunity to modify the design of your unique custom made bottle several times. Simply contact your account manager/designer and discuss if the changes that you require are feasible.
Rockwood charge only USD 850 for a design. Our company is aware that a bottle-design is critical to the success of your project. That's why you may want to change your mind before commencing the production of moulds. Paying USD 850 will allow you to revise your design three times. The USD 850 fee covers not only our designing services, but our engineers’ consulting services to ensure that your bottle can be achieved in mass production.
Most buyers believe that Europe offers a promise of quality, while China is only focused on price. Rockwood is a French controlled glass factory, managed by French technicians. Our quality is comparable to any European glass manufacturer of the same level. A quick talk with some of our existing clients will reassure you on our quality-level. Rockwood are not only able to achieve better prices than anywhere in Europe or the USA, but you also offer the benefits of a unparalleled flexibility, fast turn-around, and a dedicated team of Western technicians.
Any issues should be immediately communicated to Rockwood. If indeed we have made a mistake in the production process, or delivered sub-standard delivery to your business, we will stand 100% behind our product and take the necessary remedial action to rectify the situation.
This is a very rare scenario, but in such an event, breakage like this would be most likely to occur during transportation. It would therefore be the responsibility of the associated transportation company, and covered by the corresponding insurances. We ensure that product is loaded safely and securely in China, sufficient to withstand typical conditions as experienced by containers during freight. Rockwood however cannot be liable for abnormal conditions, for example, a dropped container which may, cause damage to its contents. It should be pointed out that such events are an extreme rarity.
Like all other bottling plant anywhere in the world; some dust, card shavings or other particulate can enter bottles and they should always be cleaned on your production line prior to filling.
For uniform 750ml bottles it is possible to fit approximately 25,000 bottles assuming they are packed in cartons on pallets. Approximately 27k if they are floor-stacked. For irregular 750ml bottles, this figure reduces to around 22k in cartons.
Approximately 60k standard 12 Oz. Beer bottles will fit in a 40HC.
Generally speaking, yes. The MOQ relates to the quantity that must be produced at one time. This does not mean that they need to be shipped all at once.
At Rockwood we pride ourselves on our flexibility and so like to provide this option to our clients.It should be remembered however that shipping-partially does not optimise your shipping efficiency and the additional costs that are incurred should be carefully observed so as to ensure that doing so is not a false economy.
Terms of partial bottle shipping can be discussed on a case-by-case basis with your account a manager.
The glass itself has no lead or other harmful chemicals. Upon request, Rockwood can have the bottles tested at an independent test facility to confirm.(SGS, TUV, Bureau Veritas)
We know and work with many bottlers around the world and we will be happy to make a recommendation of a reputable bottler close to you.
You should also note that we have our own bottling factory in Shanghai, and as such can provide finished products, as well as just glass bottles. We are able to supply an extensive array of closures, including; T-caps, screw caps, Guala (style) caps, glass-caps
From our own distillery in France, we have a permanent inventory of French vodka and French brandy XO in our Shanghai plant. This is available to our clients at short notice to minimise lead times.
There is no legal requirement to stipulate “China” anywhere on your product. We are able to provide an extensive list of products that we bottle and ship for the USA and numerous other countries. The country of origin of the alcohol and the name of the importer appears on spirits labels; however it is not a requirement to define the location in which it was bottled.
The reason we do not have to mention China is our location in an Export Processing Zone (EPZ).This is a bonded-area, technically outside of China, and recognised by other countries as being outside of China’s borders.

ENEMAL INK LABEL PRINTING also known as Applied Ceramic Labeling (ACL) is new FULL PROOF printing technology that makes your bottle décor and printing INDUSTRUCTIBLE!
We have very good news that we would like to share with you. We have just completed the setup of a new printing line in our factory that uses ENAMEL INK. This French patented technology was brought from France and is exclusive to Rockwood Glass Factory in China.
We can now print your label and guarantee at 98% that the ink will remain unchanged and undamaged for at least 100 dishwasher washings. Indeed, your glass bottles are rarely reused by final consumers in this way BUT we do know that you have quality standards to abide to when you sell to distributors and one test is often the RAZOR BLADE one: if your distributor scrapes your label with a razor blade or sand paper, will the label stay intact? Until today no label was tough enough to survive this test.
TODAY with ENEMAL INK LABEL PRINTING at ROCKWOOD GLASS this is a test that will no longer be a reason for your distributor to reject your product, as YES the label will resist any scratching even with a razor blade or sand paper!
Enamel ink is made from silicia, sand molecules, similar to the ones used for making glass. Therefore at cooking temperature of 600°C, the enamel ink penetrates into the glass bottle itself, making it (almost) indestructible!
To find out more about this new technology, please enquire. A new revolution has begun, don’t miss the opportunity and be within the first to benefit from Enamel ink label printing today.
