You remind me of someone... a man I met in a half-remembered dream. He was possessed of some radical notions.
— Saito, from the movie 'Inception'

Hand-tooled finishes are becoming all the rage with designers these days, just flip through any interior design magazine on a newsstand and you'll see countless articles and inspiration photos of beautifully imperfect surfaces. Jon Schuler, the genius behind the mix designs and sealers we employ, is a master of the complex art that is ‘upright casting.’ Jon will walk you through the processes required to make two high-end sinks by hand, devoid of conventional sink molds, resulting in one-of-a-kind products that are at home in a countryside villa in France, or a minimalistic mansion in the Hamptons. An added benefit of this style of casting is the ability to efficiently work in a small space without the need for a water-polishing area, a challenge many artisans are faced with. 

Workshop Topics will include:

  • Form building from an Upright Casting Technique (UCT) point of view
  • How to craft a handmade sink using UCT techniques
  • ICT Reactive Sealer application
  • Acid washing concrete
  • Use of orbital sanding techniques to achieve and finesse final finishes
  • Proper methods of grinding and sanding utilizing dry diamonds

Attendees of this class will craft a minimum of 2 unique sinks, a farmhouse style sink and a ramp sink with a slot-drain. The workshop format is exploratory and heavily hands-on. The simple tools employed include floats, trowels, and even your own hands! The sequence and manipulation of these tools and techniques are the secret sauce needed to boost your confidence, advance your offerings, and expand your earnings. Join us for knowledge, inspiration, and the most fun you can have while mastering a lost art!
