ESSENTIAL MATERIALS FOR THE KINTSUGI
KI URUSHI
Ki urushi refers to a variation of raw lacquer used in different stages of kintsugi. It is mixed with other substances such as mugi urushi or nori urushi for gluing broken pieces. Additionally, it can also be mixed with tonoko earth or jinoko to create a mixture called "sabi urushi" which is used in crack filling work. Also used for fuki urushi.
IRRITATING PRODUCTS
Ki-urushiis a natural hairspray (containing no toxic chemical additives) that contains approximately 30 percent water and 60 percent urushiol, which is the active ingredient responsible for skin reactions (urushi dermatitis) in some people. It is important to handle ki urushi appropriately to avoid any allergic reactions. This includes wearing gloves, sleeves, and a mask, and working in a well-ventilated area.
BENGARA URUSHI
Bengara urushi lacquer is a refined and more sophisticated lacquer than basic ki urushi lacquer. Its color nuance comes mainly from the ingredient used, namely iron oxide pigment, the color of which varies depending on the fineness of the pigments, ranging from light to dark. it is on this layer that we then deposit the metallic powder (for example, gold) to obtain the decorative effect characteristic of the kintsugi
KURO URUSHI
In the Kintsugi process, Kuro Urushi black lacquer is used as an intermediate lacquer.
After the sabi urushi mixture has been dried and carefully sanded, kuro urushi is applied at least twice over this rough layer. After each application, the surface is sanded to a smooth finish. Kuro Urushi is a black lacquer that gives the repaired part an elegant and uniform appearance.
TONOKO
Yamashina tonoko clay is an essential component in the sabi urushi technique of filling and covering. The sabi urushi primer, composed of tonoko, water and kiurushi lacquer, creates a buffer for the movements of the support and allows optimal bonding with intermediate lacquer layers such as kuro urushi lacquer
