\"Frost\u3000\"Frost<\/p>\n

The item we most wanted to make in the Frost series\u2014and the first one we made.
\nIt was the mug.
\nWe began developing the Frost Mug as the brand reached its fifth year, with one particular aim: to give shape to our idea of an everyday standard.
\nAt POTPURRI, there are things we value even more than a product's appearance.
\nBeing useful as a tool. Lasting for years. And using the artisans' skills we want to preserve.
\nWhen those considerations come together, we realize there is only a little room left for purely visual design.<\/p>\n

The Frost Mug brings together the things we value most, giving them a tangible form.<\/p>\n

Thin and light, yet strong<\/span><\/strong><\/h3>\n
\n

\"Frost\u3000\"Frost<\/p>\n

Thin enough for the tea or coffee inside to show through, and light in the hand. Weight feels different to everyone, but we wanted a balance: light without feeling too light. Thinness can make a piece fragile, so for the Frost Mug we adopted a mechanical pottery wheel, a manufacturing method POTPURRI had not used before.
\nA mechanical pottery wheel is an automatic forming machine commonly used in mass production.
\nWe had not been particularly fond of this manufacturing method. Making many identical pieces through machine settings had felt somewhat impersonal to us.
\nThe advantage of this method is that shaping by stretching firm clay creates a body that is strong even when thin. Firing it densely at 1,330\u00b0C completes the process.<\/p>\n

A little more grip<\/span><\/strong><\/h3>\n
\n

\"Frost<\/p>\n

Sandblasting the outside gives the mug a soft matte texture. It is not completely slip-resistant, but it offers a little more grip than a glossy glaze. The inside, by contrast, is smooth.
\nIt is not dramatically easier to wash, but we have made dirt a little easier to remove.<\/p>\n

What is the right capacity? An enduring question<\/span><\/strong><\/h3>\n
\n

\"Frost\u3000\"Frost\u3000\"Frost<\/p>\n

Mug size, ease of holding, weight, and what you will drink. Who will use it, and when? All these considerations circle in our minds, and each matters.
\nThat was its capacity.<\/p>\n

There is no single right answer; everyone has their own, and this may simply be ours.<\/p>\n

250ml<\/p>\n

This is the answer we arrived at with the Frost Mug.
\nOn a busy weekday morning, a leisurely weekend afternoon, or while relaxing together after dinner, 250 ml is the serving amount we recommend for a mug\u2014even if it feels a little more or less than you prefer.
\nFilling the Frost Mug about three-quarters full feels just right.<\/p>\n

Pairing popular colors<\/span><\/strong><\/h3>\n
\n

\"Frost<\/p>\n

Among POTPURRI's many gift sets, the pair of Frost Mugs is especially popular. The pale pink has a gray rim accent, making it a color we would also like men to enjoy. The refreshing green is a lovely accent even for women who usually prefer monochrome colors.<\/p>\n

\"\"\u3000\"\"\u3000\"\"<\/p>\n

Frost has a gently textured surface. The collection followed V\u00e5g, first made in 2012, five years later. It grew from a wish to make dependable porcelain for everyday use.<\/p>\n

Porcelain does not absorb water and stays strong even when shaped into thin walls.
\nThe starting points were practical: pieces should be easy to hold and serve from, and should stack well.<\/p>\n

Keeping the walls thin through firing took considerable work.
\nColour and texture posed a separate challenge.
\nThe makers used different colours inside and out, aiming for the look of a thin layer of ice.<\/p>\n

Glazes with different expansion rates can craze or crack when applied to opposite sides.
\nThe pieces still had to stand up to everyday use.
\nThe makers fired glazes with matching expansion rates on both sides, then applied the contrasting surface texture by sandblasting.<\/p>\n

The porcelain is fired at 1,330\u00b0C and finished with soft colours and texture.<\/p>\n

The coffee cup, mug and teapot have glossy interiors for tea or coffee. On the bowls and plates, the underside is glossy.<\/p>\n

Giving shape to just what you need at mealtimes<\/span><\/strong><\/h3>\n
\n

\"Frost<\/p>\n

The Frost series comprises eight items. Their sizes and forms reflect POTPURRI's ideas as well as everyday practicality. Centered on pieces for enjoying tea time, the series also accommodates Japanese, Western, and Chinese food.<\/p>\n

The hand-painted finish may vary slightly from piece to piece.
\nThe matte texture is created by sandblasting, followed by a treatment to help resist staining.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Frost means frost in Swedish.
\nIntroduced five years after V\u00e5g, which we created in 2012, this porcelain series began with the aim of making practical everyday standards. Porcelain is nonabsorbent and hygienic, and remains strong even when formed thinly.
\nEasy to hold, easy to serve food in, and easy to stack: the Frost series follows the fundamentals of tableware. Achieving its thin form through shaping and firing took considerable work.
\nColour and texture posed a separate challenge.
\nApplying different colors inside and out is a traditional decorating technique. We wanted those colors to have the texture of a thin film of ice. Using glazes with different textures on the two surfaces can cause crazing or cracking because their expansion rates differ.
\nThe pieces still had to stand up to everyday use.
\nFor Frost, we use glazes with the same expansion rate on both surfaces and add texture afterward with a special sandblasting process. The porcelain, fired at a high 1,330\u00b0C, is characterized by soft texture and color.<\/p>\n<\/div>\n<\/div>\n\n\t\tExplore the Frost collection<\/span>\n\t<\/a>\n\n
