Boston Valley has been making glazes and matching historic finishes for over 30 years. Owing to this experience and knowledge, our Glaze Lab is unmatched in the research and development of glaze finishes. Whether you are looking for a single chromatic color or a more complex finish using a custom glaze or several glazes, our glaze lab will work with you as part of our design assist services to develop the finish and fulfill your design goals. Ceramic glazes open up a world of possibilities often unavailable in a clay body and can add that final unmistakable and memorable touch to your project. While seemingly simple, color is often a deeply personal design choice that can invoke various reactions from building users and inhabitants. Boston Valley understands this and has established a workflow process which allows the designers to provide initial examples and input as well as feedback throughout the entire process.


Boston Valley Terra Cotta has a large successful history and glazes finish library to draw upon for your restoration or new construction project. Glaze finishes are available in matte, satin and gloss levels of sheen. Boston Valley Terra Cotta works with clients to produce a glaze that replicates the historic sample or color swatch as close as possible using materials available in today’s ceramic industry.


Glaze finishes open up a world of possibilities which may not be attainable for our TerraClad® products in a through-body clay color.

Boston Valley can glaze both panels and sunshade devices to achieve a different finish color or appearance than what is available in our through-body colors. Because of our specialized production processes, we can provide a glaze-wrapped end on our panels and a 4-sided glaze finish on the sunshade devices. Glaze color finishes are available in matte, satin and gloss surface types. We will work with you to understand what amount of reflectance will be appropriate for your project as well as what colors and tones are available for each surface type. Having matched historic glazes for years, our research and development lab can accept alternate material samples such as stone, metal or cloth, or paint color swatches as a basis of direction for the glaze color. Our sales team will work with you throughout the glaze development process sending you samples for your feedback until you are satisfied with the finish.


Having developed relationships with two renowned ceramic artists, Boston Valley can collaborate with them should a client desire. Boston Valley collaborated with Ann Currier on a project at Alfred University in the choral room of the Miller Performing Arts Center. Currier worked with our staff on the creation of the RAM-press profiles, glaze finish as well as the method of mounting.

Dutch artist Christine Jetten of Studio Christine Jetten is another ceramist with whom Boston Valley has a working relationship. The recently completed 175 park project in Madison, NJ showcases our successful collaboration. Jetten worked with our Glaze Lab to translate glazes originally produced in an electric kiln to our industrial gas kiln environment. Challenges such as raw material sourcing and glaze-profile interaction also had to be overcome.

Following the opening of the building, KPF principal and project architect Hugh Trumbull had this to say about the terra cotta:

“Working in terracotta is absolutely fascinating – the material is so rich and powerful. I fully believe that understanding the process of creating the material, the fabrication, the science, the art, and of course the craftsmanship, unlocks terracotta’s true potential for any project seeking design excellence. At 175 Park Avenue, Boston Valley Terra Cotta and Christine Jetten allowed KPF to explore exciting glazed elements that defined the project’s iconic architectural features. This successful collaboration elevated the building quality as a whole.”
