Penguin Pottery glazes, wedging boards and studio supplies

What does Penguin Pottery make?

Penguin Pottery is a glaze-first brand with a growing list of studio basics. Most of its glazes here are cone 5–6 (the listing gives about 2,167–2,232 °F), sold in 4 oz sets or pint and 64 oz jars. Its listings state conformance to ASTM D-4236 and a lifetime warranty on its products, and the low-fire clear says it is made in the USA.

Which Penguin Pottery product lines are in our catalogue?

• Glaze sets: Specialty Series #1, Celadon Series and Matte Series, each 7 glazes plus wax resist in 4 oz jars, listed as suitable for food contact when fired to the specified cone. The Raku set says not for food contact.
• Single glazes: Glossy Clear (64 oz, zinc-free), Off White Matte and Matte Black (16 oz), all cone 5–6, and a Low Fire Clear for cone 06–04.
• Wax resist pens, a set of two, refillable.
• Kiln wash: ready-to-use liquid (16 oz) and a 1 lb dry mix.
• Wedging boards: Medex MDF, 12 × 18 in (one handle) and 18 × 24 in (two handles).
• 14 in bat system with five square Medex inserts, and DrainSaver clay settler for sinks.

How does Penguin Pottery compare with other brands?

For glazes, Penguin's sets are smaller and more curated than Mayco's 12-color kits and sit in the same cone 5–6 range as AMACO Potter's Choice. Its advantage is the clear food-contact wording on most of its mid-fire glazes. For wedging boards it competes with LEOLIO (HDF) and lower-cost MDF boards; Medex is a moisture-resistant MDF.

If you fire low-fire only, Penguin has just one clear here, so Mayco or Sax offer more choice.
