Tannin Blend
This is a blend of NATURALLY-SOURCED Tannin, usually from Quebracho and Sumac, possibly others. It will leave your plant fibres or fabrics a soft red-brown base colour before using other dyes.
Used mainly on as a MORDANT on cellulose fibres such as cotton, usually in combination with Alum.
TO USE: weigh dry fibre. Calculate mordant required at 15 to 20%% WOF (weight of fibre) each of Tannic Acid and Alum. Weigh mordants and dissolve in hot water in separate plastic or non-reactive containers. Add wetted fibre to Alum solution and soak for 12 to 24 hours. Rinse and place in Tannic Acid solution for 12 to 24 hours. Rinse again and place back in Alum solution for 12 to 24 hours. Wash and rinse well, then dye or dry for later use.
Spent mordant solution may be safely disposed of down the drain (except for septic systems). It also may be poured around garden plants that prefer acidic soil conditions.
CAUTION: wear a mask when handling powders. Wear gloves when using tannins, particularly when rinsing or handling wet yarns as they can cause skin irritation and staining.
Thiourea Dioxide
Sometimes called Thiox. Used in the INDIGO VAT dye process, thiox removes oxygen from the vat solution, allowing the indigo to work its magic. Thiox is also a colour remover, and is used for that purpose in discharge dyeing, to create white patterns on a coloured background.
TO USE: Follow the specific indigo vat recipe, for amounts and timing.
Dispose of spent dyebath in the usual way, most likely down the drain.
Thiourea dioxide has a shelf life but it's longer than some things you read might indicate. If the powder has a distinctive yellow look, it has probably oxidized to some degree and may no longer be effective. Store in a cool, dry place out of the light i.e. in a cupboard in the house, not out in the garage.
CAUTION: Should be done OUTDOORS ONLY or with excellent ventilation. Avoid breathing fumes. Wear a mask when handling powders. Wear gloves.
Tin Mordant
Used as a MORDANT in natural dyeing, which allows the plant pigments to bond with the fibres.
Tin (Stannous chloride) brightens colours and really makes them "pop". However, it is one of the trickier mordants to use, and rather expensive. Some dyers prefer to premordant with tin, while many simply add "a pinch" at the end of the dye process, and heat the fibre for another fifteen minutes or so, cool and then rinse as usual. The amount recommended for this is only 25% of the usual premordanting amounts, below.
Used mainly on protein fibres such as wool, alpaca, silk. Tin can make fibre feel harsh and brittle, so do not exceed the recommended amounts. Yarns can also easily scorch during tin premordanting. Do not pack the pot too full of fibre! An upturned rack, marbles or stones can help keep yarns off the bottom of your pot.
TO USE: Weigh fibre. Calculate mordant required for .5 to 2% WOF (weight of fibre). Weigh tin and dissolve in hot water. Fill pot with sufficient water for the fibre to move, add tin and stir. Enter fibre. Bring to 180-200°F and hold 1 hour. Stir yarns frequently. Cool, remove fibre and wash well. Dye immediately or dry for later. Some dyers add cream of tartar at 5-10% WOF with tin.
Spent mordant solution may be safely disposed of by pouring in a gravel driveway or path.
CAUTION: wear a mask when handling powders. Wear gloves when using tin, as it can be absorbed by the skin. BEST DONE OUTDOORS or with very good ventilation. Avoid breathing fumes.
Titanium oxalate
Used as a MORDANT in natural dyeing, which allows the plant pigments to bond with the fibres.
Titanium is used both on protein and cellulose fibres, giving vibrant orange and gold tones when dyes contain tannins. As a mordant, this is relatively new and not much information abounds in books or even online. It may be the closest thing now available to replace chrome, which nobody much uses any longer.
TO USE: weigh the dry fibre or yarn. Calculate mordant required for 8 to 15% WOF (weight of fibre). Dissolve in hot water. Fill pot with sufficient water for the fibre to move, add titanium and stir. Enter fibre. Bring to 180-200 degrees F and hold 1 hour. Stir yarns frequently. Cool, remove fibre and wash well. Dye immediately or dry for later.
Some interesting results are being produced doing Eco-Printing on fabric, using Titanium as a mordant.
We cannot seem to find much information on safe disposal of a Titanium mordant bath. Nothing we've found indicates it to be particularly toxic or harmful to plumbing or sewer systems, but to be on the safe side it may be best to dispose of this outdoors on a gravel driveway or similar place.
CAUTION: wear a mask when handling powders. Wear gloves when rinsing or handling wet yarns. BEST DONE OUTDOORS or with very good ventilation. Avoid breathing fumes.
Urea (Ammonium nitrate) – 250g
Price per 250g (8.82 oz) container.
CANADIAN SHIPPING ONLY. Limit of 1 per order. We stock Urea in larger packs, including 500g and 1kg sizes available for pickup at the shop only. PLEASE CONTACT US for availability and prices: [email protected]
Due to the potential use of urea as an ingredient in explosives, we wish to handle the distribution of it carefully. Absolutely NO international orders!
We also cannot, by law, supply Urea to those wishing to use it as a nitrogen fertilizer for home garden or agricultural application.
Used mainly with synthetic dyes as an ASSIST, urea helps to open up fibres and allow for better dye penetration, and also keeps the fibre wetter for longer during direct application of dyes. This is a soluble form of urea that dissolves easily in hot water.
TO USE: Follow any of the dyebook directions for cold pad batch dyeing.
Dispose of spent dyebath in the usual way, most likely down the drain.
CAUTION: Should be used with good ventilation. Wear a mask when handling powders. Wear gloves.
Weld, Dried Chopped
Dried and chopped tops from Reseda luteola.
Use on protein or cellulose fibres. An ancient source of excellent bright yellows. Pre-mordanting recommended. Alum/c.o.t. mordant gives good results. Use at 30-50% WOF for medium shades.
TO USE: soak in water overnight, then simmer mixture at 160-175°F for 1 hour. Cool and strain. Add more water if needed and enter pre-mordanted fibre. Hold at a 160-175°F for one hour. The brightest yellows develop at these cool temperatures.
Light & washfastness: very good.
