Product Description

One Release for All Your Projects
Versatile release is designed to be used on ceramic slumping and casting molds. Ideal for use with texture molds; it even works well with intricately detailed molds Colour de Verre casting molds and hard to release shapes like holey molds from Creative Paradise. Easy spray-on formula provides uniform coating to release glass easily. Effective at temperatures up to 1800° F. 12 oz spray bottle is air-shippable.

For the first two applications, apply 2 coats allowing each coat to dry in-between. For re-application apply 1 thorough light coat.

Delphi Tips:

  • Boron Nitride seals the surface of your mold, therefore traditional primers won't absorb properly for subsequent applications. Use only Boron Nitride on the mold for all future firings to ensure your art releases from the mold.
  • After a few firings, a soft bristle brush can be used to loosen and remove old release before re-application.

  •   Excellent product
By on
Pros : Easy to apply Glass easily removed from moulds
Cons : Hard to get decent coverage without overspray. Initial mould coverage uses a lot of spray.
Other Thoughts : I used around 80% of a bottle covering 10 small to Medium sized moulds, after initial 2/3 coat coverage only one coat is needed. I suggest purchasing 2 bottles if you intend to cover several moulds.

  •   WOrks wonderfully and easy to use
By on
Pros : I love the non-aerosol version, it feels like I'm wasting less, getting better coverage, have more control over where it goes and it's easier to ship. Just like regular ZYP it cleans up easy, saves my molds, doesn't leave brush marks like kiln wash and even when I'm casting thick pieces for a long time frame it never breaks down and gets stuck in the final project.
Cons : I always prep large batches of molds to use at a time because the spray nozzle has to be fully cleaned and removed from the bottle when not in use to keep from clogging. And it takes time and wastes a bit to clean it but it's not much worse than having to prep kiln wash every time either.
Other Thoughts : I've been told that once you use boron nitride on a mold you can never go back to kiln wash because it won't stick any more, so I was hesitant to try it. ZYP is way more expensive than kiln wash! but after I had several molds damaged due to imperfect kiln wash coverage and staying power I realized, it costs way more to replace a mold than the extra BN costs to do a great job. Since I've switched I haven't lost a mold yet.

  •   Cleaning is essential
By on
Pros : Works great and half the price of the aerosol can.
Cons : It Must be cleaned after every application session. It is a bit messy so using the mud sink is a good idea.
Other Thoughts : I am considering going with the aerosol to save time and hassle.

When and how did you get started in stained glass? Ive been interested in stained glass for as long as I can remember. As a child, I would sit in churches and watch the (often) biblical depictions come to life when a stray ray of sunlight cast its illumination our way. Sun shadows dancing. I dabbled in many media over the years, trying to find an outlet for some of the visions careening inside, but none of them took. Drawing, painting - even watercolours - no amount of professional training could guide my hand in a satisfactory way. But then there was the glass. I lived abroad for a few years, and wound my way through Europe on my way back to the States when I finished my Peace Corps Service. My last international destination was Paris, where one of my closest friends lives as an organist. Two beautiful autumn

Chances are, right now, in reading this blog post, youre avoiding an overdue task. I too was avoiding a laundry list of work-related tasks in writing this. Procrastination is a part of life, and its certainly always been a part of mine. As a teenager, my parents would accuse me of putting off everything from piano practice to math homework. Id vehemently deny their charges hissing back, I work better under pressure. The truth was, I often felt overwhelmed, under-productive and anxious. Over the years, Ive been able to combat my avoidance issues using 4 tools. The trick is constantly reminding myself of these actions, because they do not come naturally to me. 1. Just Say No. I say yes to everything. Need someone to head up that event? Sure. Want me to design 12 posters for the Car Wash? No problem. Take your kid to daycare? Of course.
