Artistry. Dimension. Beauty. Individuality. The joy of not knowing exactly how it'll turn out, but anticipating it'll be great because you designed and created it. Every demolding is like opening a gift. Especially with the Terrazzo technique - which only shows its true nature after wet sanding, when the confetti-like chips are revealed.
How many coasters can I make with the Razzo Starter Kit?
You can make approximately 8 coasters.
Is Razzo the same as Jesmonite?
Razzo is a non-toxic mineral casting compound similar to Jesmonite, but with several advantages. Razzo is easier to measure, easier to mix, has a longer working time, and is more readily available than Jesmonite. Razzo can also be demolded at any time after curing, unlike Jesmonite, which should be demolded after two hours and left to cure completely (outside of the mold).
How much mixed volume does Razzo yield?
Razzo yields a mixed volume equal to the amount of Mineral Powder (Part B) used, by volume. For example, when measuring 1A:2B by volume, if you combine 2 oz. of Acrylic Liquid (Part A) and 4 oz. of Mineral Powder (Part B), the mixed volume will be 4 oz.
How much Razzo do I need to fill my mold?
Here's an easy way to estimate how much Razzo you need: Fill the mold with water, pour the water into a cup and measure the amount. Discard the water and dry the mold. Measure half that amount of Acrylic Liquid (Part A) and pour it into your mixing cup, then measure that original amount of Mineral Powder (Part B) by volume and pour it into the mixing cup and stir to mix thoroughly. For example, if you need 2 oz. of water to fill your mold, you would need (by volume) 1 oz. of Acrylic Liquid (Part A) and 2 oz. of Mineral Powder (Part B).
How do I get rid of bubbles in my Razzo casting?
Immediately after pouring, pinch the edges of the mold to release trapped air pockets. Use a toothpick to release air bubbles that are close to the surface. You can also tap the sides of your mold to release air bubbles, or lift the mold and drop it gently onto a flat surface.
When can I remove my Razzo piece from the mold?
Demold after at least one hour, when your piece is firm and cool to the touch. It may still feel a little moist, but that's not an issue. Set it aside and allow it to cure completely.
Is cured Razzo waterproof?
No. Cured Razzo is porous and should not be exposed to water/moisture for extended periods.
What can I use to seal Razzo?
We currently recommend using TotalBoat Halcyon Satin Varnish to seal Razzo and make it waterproof for use in soap dishes and other items that will be exposed to water/moisture for prolonged periods.
Is Razzo food safe, once cured?
No, Razzo is not safe for food contact. It's ideal for use as a trivet or a dinner plate charger (the decorative liner that goes under the dinner plate), but don't use it as a cheese board or charcuterie board.
