OTZI

Materials

 

OTZI is committed to sourcing the finest leathers and materials, predominantly natural materials that are regenerative and sustainable. We believe that in using the best materials available, not only do the pieces realise their full potential aesthetically, they also function better and longer. Our pieces are hand-crafted and take hours of patient work to achieve, and are a real investment for our clients. With this in mind we feel that the materials should only be the best in order to honour the quality of our workmanship and to give the piece true durability. Ultimately, we are guided by our belief that natural and sustainable materials have intrinsic beauty and idiosyncratic characteristics that synthetic materials cannot produce. Coupled with timeless design, they produce objects and pieces that will, with careful use, last and improve over a lifetime.

LEATHER

We employ predominantly pit- and vegetable-tanned leather from the UK and Europe. Pit-tanning has been practised in Europe and the UK for hundreds of years and is used by only a remaining handful of tanneries. It produces a superior leather with great tensile strength and durability, whilst keeping the beauty of the full grain on the surface. It involves grinding the bark from either oak or chestnut trees and creating a liquor, much like a tea. The hides are soaked in liquors of increasing strength for 3 months before being layered amongst scattered bark powder for 9 months. After this lengthy process they are soaked in greases and fat liquors before drying, hand dying, and finished with dubbin. All of these waxes, tallows, and fats are totally natural. The fact that the tree bark, the leather hide itself and the tanning and currying materials are all byproducts from the timber and meat industry makes this leather some of the most environmentally friendly and sustainable available today.

 

We have a strong relationship with Britain's last remaining oak bark tannery, J & F J Baker, https://www.jfjbaker.co.uk/, in Devon. Their oak bark tanned bridle leather is amongst the strongest and most sustainably produced leather anywhere in the world, taking hides from nearby pasture-fed cows and creating an incredible material almost entirely processed by hand. We also use traditional European vegetable-tanned leather which uses many of the same processes as the oak bark tanning but on a shorter timeframe. It is still a very sustainable material and much of the character and strength is maintained in the leather. Vegetable tanned leather is usually aniline dyed, unfinished, and therefore quick to impression and mark - however these marks can be buffed out.

Over time they will balance out alongside other markings that become part of the unique wear of the piece. We don’t use heavily pigmented or even semi aniline leathers that may appear cleaner and more pristine for longer because this comes at a cost to the finish, natural character and wear and those leathers tend to age poorly. All of our pieces are made to endure; we are confident they will look great decades after they were made. We therefore use olive-tanned leathers for our upholstery, which is a new method of tanning hides. It is incredibly sustainable as it uses leaves taken as a byproduct from the olive industry, which are would otherwise be burned. The hides that result are warm and gentle to the touch and can be produced in a range of colours and finishes.

TIMBER

All of the timber we use for our furniture is sourced locally from East Anglia and the South East of the UK. We work with local forest management to take timber from trees that have been either storm felled or taken down for development purposes. We work with most native timbers such as ash, oak, sycamore, elm, chestnut, beech and plane. Where they don’t impede structural integrity, we choose to keep the imperfections in the timber, utilising the amazing grain and striking character wherever possible.

LINEN

We upholster our pieces in linen for a variety of reasons. Visually it has a lovely uneven slubby texture that suits our aesthetic. It also ages very well, getting softer with age and has a durability and toughness in keeping with the leathers and timbers we make our pieces from. As with our other core materials, linen is an inherently sustainable fabric that uses less water than cottons and can be grown in poorer quality soils.
