Amaco DL-23 Dipping & Layering Ultramarine
Ultramarine from Amaco's Dipping & Layering series is a glossy, cobalt blue, powdered stoneware glaze with a light blue surface shimmer. When applied thinly, it breaks into a gray tone and remains fluid during firing. The glaze is expressive on its own and is equally suitable for combinations with other Dipping & Layering colors.
Dipping & Layering glazes are powdered glazes for dipping and pouring. Each bag contains a pre-measured dry mix that only needs to be mixed with distilled water, making it economical for studios and classrooms while providing consistent, easily layered results. The color palette is based on popular shades from the Potter’s Choice series.

You should be able to focus on your project while pottery-making, not on whether your desired glaze is currently in stock. That is exactly what we are here for.
With over 300 colors in our range, it can happen that a shade is occasionally out of stock. The Formwerk difference: you don't have to search in multiple shops, wait for a service response, or accept any extra costs. If a glaze is sold out with us, we take action manually for you and search for your shade in our European dealer network of 12 partners. We cover the additional shipping costs.
That is our guarantee: every glaze in our range remains permanently orderable. So that you can plan ahead and have a reliable source for your glazes.
