Product Information
ZYP Boron Nitride Spray 12oz. Ideal for ceramic casting moulds. Not suitable for stainless steel moulds. Can be shipped worldwide.

This high quality Boron Nitride spray has been specially formulated for glass artists, giving you a premium finish every time. The water-based release primer works perfectly for ceramic slumping and casting moulds. 

Key features:

  • This non-hazardous spray is AIR SHIPPABLE SO CAN BE SENT TO EUROPE
  • Easy release spray-on 12oz bottle
  • The best release available for texture moulds and Colour de Verre casting moulds
  • Can go to temperatures as high as 1800F

Working notes:

  • Once Boron Nitride has been used on your mould, you cannot put traditional primers such as primo on top. Use only Boron Nitride for all future firings.
  • This spray Boron Nitride is not suitable stainless steel or metal moulds.

Instructions (included on the bottle):

  • Shake vigorously until marble is heard and there is no sediment
  • Uncap and save the cap. Always start with a clean sprayer/tube and screw it onto the bottle
  • Test the sprayer on cardboard. Spray lightly (using side to side motion) on the mould and allow time to soak in and dry. Please note: This will take longer to dry than solvent based aerosols
  • Once coating is dry to touch, reapply a second coat if desired or there are bare spots
  • Wet coating can be smoothed with a small brush
  • Allow time to dry before using. Can be dried at room temperature or with a dryer
  • After use, remove sprayer and flush with water. Recap bottle with original cap
For stainless steel moulds, use our Premium or Economy Boron Nitride sprays.

I have used ZYP Boron Nitride spray, the aerosol version for a long time and it is a very good product, one which alas Warm Glass does not sell. As this appeared to be a cheaper option of the same product and less hazardous I thought I would give it a trial.
In use I did not like it as much as the aerosol version, which produces a very smooth finish and is surprisingly economical, it also dries very quickly and the mould can be ready in about 15 minutes. I found this water based version very difficult to apply smoothly. I did 4 small slump moulds and I was surprised just how much of the bottle it had used, the surface felt soft for a long time so I left it overnight before using. It worked OK and there was no issues with release, though the contact surface finish was not as smooth. I have just re-ordered more of the aerosol version and will keep this as a back-up.

Pour ma part, les résultats sont mauvais en général, le spray est trop fort et le produit est déposé trop épais sur mes petits moules (faut il le racler?). Trop de produit cuit à la cuisson et laisse des traces blanches dans le verre...Le mieux c'est de tamponner le produit avec de la ouate en plusieurs fois, c'est plus délicat. Sinon je repasse au spay en bombe pour mes travaux en grande taille, plus rares qui demandent beaucoup de contrôle.

The product is good but the spray bottle not so good! I decant it into a little plastic spray bottle every time I use it and shake, shake, shake. Then shake some more,
I’ve previously wasted lots of money on aerosol Boron which clogs up after a couple of uses and never works again so this is a great alternative

Spray got blocked the first time I tried to use it despite following instructions. Attempted again after soaking the spray and adding more beads in the bottle. Came out in large drops. I would not recommend this. Need to replace my shelf.
WARM GLASS REPLY: I'm sorry you were disappointed with this product. A member of our Customer Services Team will be in touch with you shortly.

This product is very easy to use and gives excellent smooth results.
I have used it on simple and more detailed moulds and there is no loss of definition.
