Use :
Natural dye – mordanting and nuancing any fibers : iron is the basis of all grey and black shades by reaction with natural tannins. In a general way, it is used to darken colours and make them deeper. It slightly improves light- and wash-fastness from those obtained with aluminum mordants. Recommended use at 1-3 % of the Weight Of Fiber (WOF). A higher % may alter the structure of proteinaceus fibers and make them breakable.

For grey and black shades, we also recommend to use our extracts of logwood, oak gallnut, sumach gallnut, tara, acacia. The best results will be obtained with combinations of these extracts.

Also, combinations of aluminum and iron mordants or a last (very light) iron bath after a aluminum-mordanted-colour will widely increase the number of shades.

Uses :
Natural dyeing – mordent for cellulosic fibers and leather :
Titanium oxalate is mentioned in several books as a mordant for dyeing cotton and leather.
It provides a better fixation of natural tanins and bright oranges (for instance with the oak gallnut extract or sumac gallnut extract or the tara extract). In combination with natural dyes, you will get new ranges of shades, especially bright oranges with yellow natural dyes (for instance with the weld extract).
By creating stronger complexes between the fibers and the dyes, titanium mordent contributes to better lightfastness and washfastnesses.
Titanium salts are currently extensively developed in replacement of chromium salts for environmentally friendly titanium-tanning techniques.

Uses :
Natural dyeing : it is used to stabilize aluminium acetate in fibers. Calcium carbonate can also be added to madder dyebaths when the water does not contain enough calcium to brighten red shades.

Other uses : inorganic filler in paints, domestic uses… Sometimes also named Whitening agent, Blanc d’Espagne, blanc de Meudon.

Iron gall inks: The iron sulfate is the basis of this historical ink where it is associated with tannins, in particular our very rich gallnut extracts from oak or sumach.

Paintings and wood treatment : ferrous sulfate is used for reactions with tannins (formation of complexes) and its antifungal properties. It gives to wood tipsy finishes or darkens them according to species.

Other uses : Gardens and lawns (antimoss).

Use :
Natural dyeing – mordanting any fibers : potassium aluminum is the easiest and most popular mordant used with natural colours. It does not change the shades and is necessary for a good fixation of the natural colours.

For protein fibers (wool or silk), we recommend to use the alum associated with cream of tartar that improves the fixation of alum to the fiber.
For cellulosic fibers (cotton, linen, hemp, abaca…), we recommend to use alum in association with sodium carbonate. If you prefer to use a single product, you can also select aluminum acetate instead of alum.

Also, combinations of aluminum and iron mordants or a last (very light) iron bath after a aluminum-mordanted-colour will widely increase the number of shades.

Natural inks : potassium alum both contributes to stabilize the natural dyes molecules (by complexation) and to better develop their colour. Our plant dye extracts can be used for the preparation of natural inks, for instance in combination with arabic gum. Alum has also bacteriostatic properties on certain bacteria and plays a role on the preservation of products.

Natural paints and coatings : in lime coatings, a small proportion of alum accelerates the crystallization and  hardening. It also allows to fix pigments and to deepen colours in milks, paints or lime mortars. It hardens plasters and clays.

Other uses (for instance) : treatment of leathers and tanning.

This tartaric acid is isolated from by-products of the wine making (white wines generally). Water is the only solvent used in the manufacturing process. Product of food grade – food ingredient (E334).

This ingredient is PREPARED BY UP-CYCLING OF BY-PRODUCTS FROM THE WINE INDUSTRY.

Uses :
Natural dyeing : for the mordanting of wool and silk, in addition to alum, tartaric acid gives different shapes than those obtained with the cream of tartar. Recommended also for cochineal dyeing.

Other uses : as an organic acid, pH adjustment, reducing agent, complexing agent and setting retardant for plasters and cement compositions. Formerly used as photographic developer.

This cream of tartar is precipitated, then purified, during white wines making. This is a food ingredient (E336), also named potassium bitartrate and it does comply with food regulations.

This ingredient is PREPARED BY UP-CYCLING OF BY-PRODUCTS FROM THE WINE INDUSTRY.

Uses :
Natural dyeing : Cream of tartar is very useful for the mordanting of wool and silk, in association with potassium alum. It does improve the binding of mordant on the wool and the silk, makes shades brighter and contibutes to a better uniformity of colours. It also has anti-felting properties and protects the fibers during the mordanting and dyeing steps.

Cream of tartar  is also very helpful, in association with alum, for the mordanting of raffia, sisal or abaca fibers, even if these are cellulosic fibers.

Other uses : Baking powders, wine care, cookie, candies, pastries, toothpastes, metals care…
