Nano-SHINE solves the age-old problem of tarnishing on silver, gold and other precious metals. These items fall into disuse, lose value and are even consumed by the tarnishing process. Nano-SHINE resolves this problem once and for all, allowing people to enjoy quality silver and gold jewellery, cutlery and other items without care for cleaning or degradation over time. Nano-SHINE is also relevant in ensuring longevity in applications where precious metals are chosen for their non-aesthetic properties, for example conductivity in electronics. We want to make Nano-SHINE the de facto finishing treatment for silver, gold and precious metals, and to make it accessible to all manufactures and users. This will be achieved through an expansion of the business, creating treatment centres local to relevant manufacturing clusters and with the development of a user-friendly machine, which will be leased to the largest manufacturers to allow them to self-treat their products, on a pay-per-use basis, without revealing the technology behind our process.
