He made simple utilitarian and decorative pottery, that was sold, among others by "t Binnenhuis and Metz & Company
Gerrit de Blanken manufactured exclusively turned pottery.
His work has a sober style, and is often very thin. Striking is the frequent use of different colors for the interior and exterior of a container or dish.
He also produced ceramic designs by Chris Lebeau. One of his students in Zoeterwoude was Hans de Jong.
His work is also included in the collection of the Gemeentemuseum in The Hague, the Museum Boijmans Van Beuningen in Rotterdam, and the Princessehof Ceramics Museum in Leeuwaarden.
