Part of the Cernit Alcohol Ink range, made in Belgium by The Clay and Paint Factory. Supplied in the same 20ml dropper bottle as the colors.

What this is: a diluent for thinning the inks, lightening a color, or keeping a wash moving on the surface longer. It is not just alcohol — it carries something glycerin-like that makes it flow more smoothly and stay workable longer than neat alcohol does.

Shipping note — please read before ordering. This product is classified as a hazardous material by USPS and UPS, so it cannot travel by air. Any order containing it moves by ground carrier, and that applies to the whole box — anything packed alongside it ships ground too. If an order is large enough to need a second box, that box can go by the usual service.

Ground shipping on hazardous materials has sometimes run slower than an ordinary ground shipment. We ship from outside Seattle, so the further east you are, the more time to allow. If you need it by a particular date, please order with room to spare.

On availability: the same restriction applies to our own inbound stock — it crosses by sea rather than air, so restocks are infrequent and lead times are long. When a color is here it is worth buying; when it runs out it can be a while before it returns.

Ginger Davis Allman tested the whole range, including how each color holds up in sunlight, in Cernit Alcohol Inks on polymer clay at The Blue Bottle Tree. Her Using Alcohol Inks with Polymer Clay covers technique more broadly.
