A sculptor, a Denver showroom and a blog called Tile Envy.

Clé is a tile brand founded by Deborah Osburn, and it began life on the internet rather than in a shop. The trade magazine Kitchen & Bath Business reported on 8 June 2012 that a new online resource called clé had recently been launched by Osburn, presenting handcrafted artisan tile from studios in California and Pennsylvania as well as South Africa, Scotland, Canada and England. The same report explained the name: clé, pronounced “clay,” is a play on the classic tile material and on the French word for key. The company still writes its name in lowercase on its own site.

Osburn’s route to tile was not a direct one. A 2017 profile in SPACES magazine says she trained as a sculptor, earning a fine arts degree at the Kansas City Art Institute, and then took a sales job in a tile showroom in Denver, where colourful tiles from Japan and Italy first caught her attention. After moving to San Francisco in 1986, the magazine says, she worked as a kind of gallerist for tile, sourcing terracotta, stoneware, lithographed cement, stone and porcelain mosaics and patterned tiles from Morocco. She also created a line of slender accent tiles, sold under the name Bisq’ettes through Home Depot and Lowe’s, before that business passed out of her hands.

The immediate origin of clé was writing. Both SPACES and the company’s own “our story” page say it grew out of Tile Envy, a blog Osburn started about tiles she loved but found hard to buy, which later became a book of the same name. SPACES quotes her saying that within weeks readers were asking about particular tiles and artists were approaching her, so that selling online followed naturally. The company says clé started with one person working from a garage.

Artists, a watermark and a guild behind the studio.

From the start the brand presented tile as the work of named makers. The 2012 Kitchen & Bath Business report described tiles that were carved, painted, silkscreened and lithographed, ranging from a crude recycled-clay subway tile to an industrial glazed brick, and said Osburn’s goal was to highlight and give access to the artists behind them. By 2017, SPACES was listing collaborations with the South African artist Ruan Hoffmann, with Boris Aldridge and Timorous Beasties from the United Kingdom, and with the Berkeley fashion designer Erica Tanov. The magazine described clé as a Sausalito-based online tile showroom.

One of the brand’s most recognisable looks came from an experiment. SPACES says Osburn dipped a piece of low-fired, unglazed porcelain tile into a glass of indigo dye and forgot it; days later the dye had wicked upwards into a pattern resembling shibori textiles. A designer saw the sample and commissioned a batch for a fireplace in San Francisco’s Presidio Heights, and the result became the Watermark line, which the magazine said was being produced by Osburn’s son Luca, together with a newer wave pattern called Tides.

Making tile in-house came later. The company says that when Osburn could not find a glazed thin brick she wanted, she decided to make it, and the clé guild was set up in 2019 in a building behind the clé studio. A company post dated 10 November 2023 says the guild’s first two lines, clé Guild Fundamentals and clé New California, were launched in 2019 and 2020, and that the tiles are handmade by Eric VanderMolen and his team of artisans. The same post says the guild works from a single clay with minimal additives and glazes made with minerals and natural stone powders. Today the site sorts its range by material, from stone and zellige to cement, brick, terracotta, terrazzo, ceramic and metal.

Design and documentation.

Tile makers and tile brands sit at many different points in the trade, from small studios where a design is pressed, glazed and fired by hand to large manufacturers whose surfaces are sold through showrooms, distributors and home-improvement stores. Some names make every piece themselves, some import what they sell, and some do a mixture of both under one label.

A tile brand’s identity is usually carried less by a single product than by a repeatable vocabulary: a family of glazes, a set of patterns, a way of edging or texturing the surface, and the catalogues and showrooms that present them. Because a name can outlast its founders, change owners or move its production, the questions behind each one are worth asking plainly: who started it, who owns it now, and where its tile is actually made.

Each guide separates what independent sources record from what the company says about itself — its founding story, its owners over time, where its tile is made and how its look has changed — and marks plainly what rests only on the company’s own word.

From online showroom to a studio that makes its own tile.

The brand has kept widening what it does. The company’s “our story” page describes clé as a history lesson, an art gallery, an education resource and a design laboratory, and says that in 2024 Osburn launched OUTERclé, a line aimed at outdoor spaces. An interview published by aspire design and home on 27 April 2026 said clé had evolved from a curated online showroom into a design-driven studio that develops and manufactures its own collections, and named OUTERclé and a customisation programme called ColourLab among its recent initiatives. In that interview Osburn summed up her design philosophy as “constant discovery and exploration,” and named cinema, particularly colour cinema, as a favourite source of ideas.

Collaboration remains part of the identity. The clé site lists collaborations with Cristina Celestino, Fornace Brioni, Zio + Sons, Giovanni De Maio and Reath Design alongside Erica Tanov, and gives Osburn her own place among the brand’s “visionaries.” Its collections carry names drawn from history and film, such as a series called 17th century: maiolica de delft and a cinema collection that includes a checkerboard design.

The site also groups tile by room, from kitchen backsplashes and shower walls to fireplace surrounds and mudrooms, and by colour and shape, and it runs a blog and an education section alongside the shop. The Lapidary range presents limestone, marble, slate and travertine as a stone library.

For a design guide, clé shows how a brand born as a blog can keep an editor’s voice while it moves from selling other people’s tile to making its own. Compare Fireclay Tile and Heath Ceramics, two other California tile names. For this guide we use indigo, terracotta, zellige white and plaster with a serif, an unofficial interpretation; no product or logo is reproduced.
