Wax for art casting and precision investment casting

Casting waxes for lost wax and precision casting

We supply waxes from Remet – a leading formulator for art foundries and precision casting. Our product range includes raw material waxes (paraffin wax and microcrystalline wax), artist/unfilled waxes for sculpting, slush, and brushwork, jewelry injection waxes, precision/filled waxes for dimensional stability, and auxiliary waxes for assembly and repair. Developed for the lost-wax method in sculpture, jewelry, and precision parts: clean melt, reliable flow, and low shrinkage .

Why choose our casting wax?

• Remet quality : consistent batches for art and precision applications.
• Full workflow : modeling, slush, brush skin + backup , injection and cores.
• Fine detail in silicone molds , predictable shrinkage and efficient dewaxing.
• Unfilled & filled grades matched for stability, hardness, flow and melting point.
• Technical advice and customization in collaboration with Remet.

Raw material washing

Microcrystalline wax

Often blended to lower the melting temperature and reduce stiffness. Can also be used as a simple casting wax. Smooth texture and easy to combine.

Paraffin wax

A widely used, economical base wax to reduce melting temperature and stiffness in blends with casting wax. Slightly more granular than microcrystalline wax.

Artists/Unfilled Waxes (Modeling, Slush, Brush)

• Modeling wax – moderately hard – for modeling . Relatively hard, softens at body temperature , yet firm enough for warm studios/large projects.
• Hard modeling wax for larger models or when extra stability is required. Can be modeled at body temperature and is dimensionally stable.
• Casting Wax Art (slush) – ideal for slush casting . Low shrinkage , hard and slightly stiffer (great for knife corrections). Less spreadable; use a repair wax for smoothing repairs.
• Casting Wax 81 (unfilled) – widely used in precision and art foundries. Suitable as a casting and slush wax. Slightly harder and with low shrinkage compared to Casting Wax Art.
• Brush Wax – Brushes in silicone molds for maximum detail , very low shrinkage , and minimal air entrapment. Apply thin skins and support with a backup wax .
• All-purpose wax – cost-effective , relatively hard; usable as a (slush) casting wax and backup wax. Often used for casting sprues and vents .
• Jewelry wax – especially for small jewelry. Works excellently in high-detail silicone molds, is quick to use , and flexible enough for difficult demolding.
• B95 Jewelry Injection Wax (unfilled) – for injecting jewelry models and sprues. Flexible , sharp detail , lower melting point than standard jewelry wax.

Precision / filled waxes

Filled waxes are primarily used in precision foundry work . The filler increases dimensional stability and limits shrinkage and settling . They are more viscous and must be continuously stirred in the molten state to prevent separation. Some grades are suitable for injection molding ; others are processed as pastes .

• B76T (lightly filled) – for small to medium-sized cartridges. Low melt viscosity for good flow and efficient dewaxing . Lower filler content and harder than B59, with a higher melting point .
• B59 (lightly filled) – for small to medium-sized cartridges. Low melt viscosity , excellent flow, and efficient dewaxing . Higher filler content and lower melting point/hardness than B76T; typically even less shrinkage/decline .
• B89 (lightly filled, aviation) – for small to medium-sized cartridges in aviation and high-spec applications. Very high filler content , dimensionally stable , yet highly flowable .

Auxiliary washing (assembly, repair & special)

Technique & processing tips

• Lost-wax techniques : build up brushwork for detail and support with a strong backup layer .
• Slush casting in silicone molds gives quick, hollow shapes with low shrinkage .
• Injection : Keep temperature stable for flow and reproducibility.
• Filled waxes : stir continuously in the molten state to prevent the filler from settling.
• Dewaxing : Choose grades with low ash and clean melt for shell integrity.

Choosing the right wash

• Method : sculpting / slush / brush / injection / backup / cores.
• Stability vs. flow : Choose filled for low shrinkage and dimensional stability; unfilled for flow and finishing .
• Melting point & hardness : adjust to workspace, model size and handling.
• Detail level : brush wash for highest detail , slush for hollow shells .
• Jewelry : Use Jewelry Wax or B95 for small, sharp details.

Frequently Asked Questions

What is “lost wax casting wax”?

Waxes formulated for investment casting : model building, tree mounting, and clean dewaxing from the ceramic bowl.

Is paraffin wax for candles or a paraffin wax bath suitable for casting?

Candle paraffin and paraffin hand bath are consumer/spa applications with different properties and safety requirements than precision casting. Our paraffin wax is typically used as a base/blend wax in the casting process.

Is paraffin wax poisonous?

Paraffin wax is generally non-toxic when used normally. Always work safely: avoid overheating, ensure ventilation, and follow the product instructions.

What is the difference between microcrystalline wax and paraffin wax?

Microcrystalline wax is generally smoother and offers better cohesion/toughness; paraffin is more economical but more granular . In blends, the melting point, stiffness, and flow are adjusted to the desired casting technique.
