Custom Design

I offer a free custom design service.  Email your project outline details, sizes, preferences and design ideas, along with the reference numbers of any images that caught your eye on this website. I will get back to you (normally within 2 working days) with some broad design considerations/options, price estimates and production/delivery time lines.
I work closely with you, your designer, architect and contractor to work up a final design. The exploration and consultation stage is easily done via emails and phone calls. I provide you with updated price estimates as concepts are developed.
Some projects may require you to have small patina samples. These will be mailed to you as required.
Depending on the size, complexity and detailing of the project, the design consultation process may take a couple of days or several weeks.

All projects that are to be shipped and installed by your contractor are carefully detailed to ensure a simple and straight-forward installation. I can do local (Auckland) installations if required.

Fixed Price Quotes

Once a final design is agreed upon, a fixed price quote is provided with the agreed final design/specifications. This will clearly identify if shipping, insurance and installation is included or excluded.
This is a fixed quote, not an estimate. It will not increase unless you or your agents make changes to the agreed design/specifications.

Placing The Order & Payments

A 35% deposit is required for all custom-made orders. For projects over NZ$5000, stage payments will be required. In all cases, the outstanding balance is due prior to shipping. Payments can be made by internet banking, bank wire transfer, or TransferWise. https://transferwise.com  Other methods are available but may incur high bank fees.

Cancellations & Returns

If you wish to cancel a custom-order, let me know ASAP. Once project-specific materials are purchased or workshop time has been incurred, these project-specific costs will be deducted from the deposit before any reimbursements are made. Please contact me immediately if you have any problems with your order once delivered. I will work with you to achieve a solution.

Shipping & Insurance

New Zealand

I generally use NZ Post ‘ParcelPost Tracked’ service. This service enables tracking your parcel on-line and also provides compensation cover up to $250. For higher value items, their premium ‘Courier’ service is a better option as it provides cover to $2000.
Please allow 2-3 days for New Zealand destinations.

For items that are very large or >30kg, I will obtain prices from freight companies and include these as itemised costs in my estimates and quotes. To keep costs low, I do not mark-up on shipping and insurance costs provided by third parties. If you are local, you can collect from my studio in Auckland.


I generally use NZ Post ‘International postal service’. This is the most economical method for small items (less than 20kg). It does not provide tracking but it does provide cover up to NZ$2000. NZ post claim 3-10 days delivery target. I suggest you allow 2-3 weeks for Europe & North America as there may be delays at customs.
For higher value items, their ‘International Courier’ or ‘International Express Courier’ services are available and provide online tracking and insurance cover up to NZ$10,000 cover.

For items that are very large or >30kg, I will obtain prices from freight companies and include these as itemised costs in my estimates and quotes. To keep cost low, I do not mark-up on shipping and insurance costs provided by third parties. If you have a preferred carrier, I can work in with that.

Customs Duties & Taxes

These are always excluded from my quotes and shipping costs. You are responsible for any customs, import taxes & duties, etc that may be applied by your country authorities.
I have found that items that can be correctly classified as original artwork are generally rated duty free by most countries. Most other items appear to fall under their tax point and incur no duty. I can do some online research to offer suggestions on what the taxes may be for your order, but this is to be considered informal and non-binding advice. You should check with your country’s import duty authorities or agents to best understand the potential import duties, taxes and the like.

How To Buy Wall Sculptures & Paintings From Gallery Stock

I produce my geometrical abstract paintings and metal wall sculptures either as a customer commissioned artwork, or as a speculative work. These speculative works are available for purchase via my on-line outlets [www.saatchiart.com], T&C’s for payments, shipping, etc are typically set by the hosting site.
Alternatively, you can purchase some works direct from me. [For Sale]. Email me to confirm current availability shipping costs.
For T&C’s regarding payments, shipping, cancellations, returns, etc, please see the relevant sections above.

How To Buy Small Pre-Made Objets d’Art

These include a range of custom designed desk organisers that are handmade from solid copper & brass with a patina finish.
I also occasionally buy old brass & copperware and give them a new life by refinishing these articles with a new patina. I sell these via online outlets or at local (Auckland) craft markets.
Some of these can be viewed at my current online shops:
Visit my acid patina Etsy.com shop
Visit my Trademe.co.nz store
If you want a custom variation, drop me an email; include any ref /SKU numbers that are with those images.
For T&C’s regarding payments, shipping, cancellations, returns, etc, please see the relevant sections above.

About Copper Patinas

Basically, a patina on copper or brass is what rust is to steel and iron. More technically, a metal will form a corrosion layer as a means to come into an energy balance with its environment. Bright copper has a very high energy. It is unstable and will move to a lower energy (tarnish) if the environmental conditions facilitate this change. Conversely, copper with a blue/green patina has a very low energy level. It is very stable and durable under normal environmental conditions. Copper patinas that are black, red or bronze are mid-way on the energy line. If they are exposed to very aggressive environments, they may start to develop blue/green patinas, or be stripped back to the bright copper.

Unlike steel or iron, copper and brass have the rare property of being able to produce a wide range of beautiful patina colours that are long-lasting and adherent.
A natural patina can develop on copper over many years exposure to the weather and natural environment. However, there is very little control of the final colour or uniformity with naturally formed patinas.
The process of achieving an attractive and durable patina is a blend of science and artistic skill. The art of applying specific chemicals to the surface of a metal to produce a desired patina colour dates back to pre-Egyptian times. The processes have been developed and widely used to colour bronze statues and similar objet d’art over the centuries. The selection of metal and the chemical formula to use is no more important than the way the formula is applied to the metal.  Every chemical patina exhibits subtle nuances in it colours and patterns. While a fair degree of control can be exercised during the patina process, only God and nature determine the final result. It is these subtle differences that ensure each patina is a truly unique work of art.
The patinated wall sculptures and décor products I make are generally intended for indoor use and have a wax or lacquer finish. The patina colours typically exhibit no change even after 10-20 years.

Wax & Clear-Coat Lacquer Finishes

Internally, clear-coat lacquers are frequently the preferred option for walls, bar fronts, cabinet doors etc. as they provide a durable, high-gloss, easy-clean surface. As they are not exposed to high levels of damaging UV light, their life-span can be decades, or more.
Metal wall sculptures may be either clear-coat lacquered, waxed only, or a combination of lacquer with a wax top finish. This last option reduces the gloss level of the lacquer to a softer mid-sheen.
I do not use clear-coat lacquers that are formulated to produce a satin or matt finish. I find these can produce a whitish haze caused by the matting agents. A very nice matt finish is possible by carefully using ultra fine micro-abrasives on the gloss clear-coat.
For custom-made projects, the finish will be discussed and agreed to prior to quoting. Samples can be provided during our consultations.
For some works, especially my wall sculptures, the design can incorporate contrasting areas of high gloss and micro-abraded matt.

Externally, in a semi-protected environment, e.g. porch protected, waxes can last months or years. When the wax starts to degrade, they cause no damage to the patina and can be easily renewed.
I do not recommend clear-coat lacquers for external situations as they will eventually breakdown under UV light and cause significant long-term maintenance issues and damage the patina.

External patinas that have full exposure to the weather will likely require regular cleaning and re-waxing. Alternatively, the patina can be left to weather naturally. Depending on the patina used and the local environmental conditions, the patina may remain stable or show some secondary patina developments. As a general rule of thumb, bronzed, red or black patinas may develop areas of blue/green verdigris over time in industrial or marine environments.  Where the supplied patina is a blue/green, colour shifts are not expected as these are the most stable and basic forms.

Care Of Patinas

Wax is easy to maintain; very similar to waxing a car. Depending on the environment and your personal preferences, re-waxing may be required once every 6 -12 months in aggressive environments, to once every 10 years or more in protected environments. Should re-waxing be delayed, no long-term degrade of the patina would normally be expected, other than a slight dulling of the colours and loss of sheen. A re-waxing would effectively restore both the sheen and vibrancy of the colours.

Recommended Wax Products.

Since 2014 my preferred wax is Ice Wax by Turtle Wax. This is a synthetic polymer wax. It is very durable and best of all leaves no visible residue around fixings and sheet edges. I have had very good results using pure carnauba wax. However, this wax can leave a yellow/white residue around fixings etc. This can be removed using small soft brushes, but this can take some time and persistence.
Both of the above waxes are normally readily available from auto parts shops.
I avoid bees wax as it remains soft and will tend to attract dirt.
Do not use any wax product that claims to be ‘rejuvenating’, ‘oxide removing’, ‘cutting’, ‘contains cleaners’, or other such claims. These will likely contain compounds that will damage the original wax and could damage or strip the patina. Furniture polishes and waxes should be similarly avoided. If in any doubt, contact me.

Clear-coat lacquers are virtually maintenance-free.
Both wax and lacquer finishes can be easily cleaned with a soft, clean, slightly damp microfiber cloth. I do not recommend the use of any chemicals, household cleaning products or any form of abrasives. If in doubt, please ask before using anything other than a clean, soft, damp cloth.

Should a patina become damaged I strongly recommend contacting me before attempting any repair. It is often best to do nothing than try and affect a repair that can end up looking far worse than the original damage.

Colours Seen on Website

The colours presented on this website are as accurate as I can reasonable achieve. I use a colour calibrated camera, scanner and monitor to ensure image data is accurate. Your browser and monitor settings, as well as the ambient lighting may affect the colours to some degree. For most cases, your device factory setting will produce colours that should be close to the true sample.
If you feel you want to check your device, Google ‘monitor calibration’ for links to some very helpful sites. The Gamma test/setting is the most important and fairly easy to correct if needed.
Real patina samples can be mailed during the custom-design stage.
