Gypsogem is an eco-friendly material that can be used by artists to create stunning creations from trinket trays to jars for candle making, coaster with loads of possibilities to unleash your creations. One can also incorporate with epoxy to create stunning master pieces. It is widely used to make decorative moulded objects. It is safe to use and contains no harmful chemicals. It has a smooth semi-glossy finish and is easy to work whether using the water or resin hardener method.
- LETS DISCUSS RATIOS
You have 2 options, either mix with water or resin hardener
- Mixing with WATER – Measurements is WHITE 100 grams powder to 26-30grms. We used 28grms water. Ratio is 1 : 3.57
- Mixing with WATER – Measurements is BLACK 100 grams powder to 36-40grms water. We used 40grms. Ratio is 1 : 2.5.
- Mixing with RESIN HARDNER – Measurements is 100 grams powder to 40grms resin hardener. Ratio is 1 : 25.
When to use what? In the process of creating Gypsogem jars for wax vessels, the application of a hardener is a crucial step to prevent wax leakage when the candle is lit and begins to melt. Hardeners serve to reinforce the jar’s material, ensuring that it remains impermeable and retains the wax effectively. This is particularly important as the heat from the candle can cause the wax to become more fluid, increasing the risk of seepage through any porous areas. By using a hardener, you create a more durable and reliable container for the candle, enhancing the overall quality and safety of the final product.
- HOW MUCH DO YOU NEED IF USING THE WATER METHOD
To calculate the amount of Gypsogem Powder required, follow these steps:
- Begin by placing your mould on a scale. Ensure that the scale is zeroed with the mould on it, so that the weight of the mould itself is not included in the measurement.
- Next, fill the mould with Gypsogem to the desired level. Carefully note the weight indicated on the scale, which represents the volume of the mould that needs to be filled.
- The final step is to calculate the amount of Gypsogem powder needed. Multiply the weight of the Gypsogem in the mould by 2.5. This calculation is based on the density and specific volume requirements of Gypsogem powder when mixed with a binding agent or liquid to form a solid cast.
- For example, if the scale reads 100 grams after following the above steps (excluding the weight of the mould), then the amount of Gypsogem powder required would be 250 grams. This is because 100 grams multiplied by the factor of 2.5 equals 250 grams.
- Remember, this calculation assumes that the density of the Gypsogem in the mould is consistent and that the powder will be mixed according to the standard ratio. Adjustments may be needed based on the specific characteristics each style or type of mould used.
Calculate the amount of water required, follow these steps:-
The mixing ratio of water to Gypsogem is 28 grams of water per 100 grams of Gypsogem powder. To calculate the amount of water required to mix with Gypsogem powder, follow the given ratio: 28 grams of water for every 100 grams of Gypsogem powder.
As per the step above in point 2, when measuring the amount of Gypsogem powder required which was 250 grams and the calculation steps for water is as follows are:
Divide the total amount of Gypsogem powder by 100 to find out how many times the ratio quantity fits into it, for example: –
WHITE POWDER
- 250 grams of Gypsogem white powder / 100 grams = 2.5 ratio
- 5 x 28grams of water = 70grams of water
Therefore, for 250 grams of Gypsogem white powder, you would need 70 grams of water to achieve the correct mixing ratio for the mould you used to measure the powder.
BLACK POWDER
- 250 grams of Gypsogem black powder / 100 grams = 2.5 ratio
- 5 x 40grams of water = 100grams of water
Therefore, for 250 grams of Gypsogem black powder, you would need 100 grams of water to achieve the correct mixing ratio for the mould you used to measure the powder.
- HOW MUCH DO YOU NEED IF USING THE RESIN HARDENER METHOD
Calculate the amount of resin hardener (if not using the water option) required, follow these steps:-
The mixing ratio of water to Gypsogem is 40 grams of hardener per 100 grams of Gypsogem powder. To calculate the amount of resin hardener required to mix with Gypsogem powder, follow the given ratio: 40 grams of hardener for every 100 grams of Gypsogem powder.
As per the step above in point 2, you will measure out the Gypogem powder the same way, when measuring the amount of Gypsogem powder required which was 250 grams and the calculation steps for resin hardener is as follows are:-
WHITE POWDER
Divide the total amount of Gypsogem white powder by 100 to find out how many times the ratio quantity fits into it, for example: –
- 250 grams of Gypsogem white powder / 100 grams = 2.5 ratio
- 5 x 40grams of water = 100grams of resin hardener
Therefore, for 250 grams of Gypsogem white powder, you would need 100 grams of resin hardener to achieve the correct mixing ratio for the mould you used to measure the powder.
BLACK POWDER
Divide the total amount of Gypsogem black powder by 100 to find out how many times the ratio quantity fits into it, for example: –
- 250 grams of Gypsogem powder / 100 grams = 2.5 ratio
- 5 x 57grams of hardener = 142.5grams of resin hardener
Therefore, for 250 grams of Gypsogem black powder, you would need 142.5 grams of resin hardener to achieve the correct mixing ratio for the mould you used to measure the powder.
- HOW TO MIX
- From the above 2 methods provide place the water and or resin hardener (only use ONE option, do not use both), with the powder and mix. The consistency will be runny.
- At this stage you can mix your preferred colourant, mica powder or inks, bearing in mind that your mixed colours with white the effect will be of a lighter result, more drops will give a richer look. You can also brush you mould with foil then pour in the Gypsogem over it to give some extra effect. Possibilities are endless.
- Pour the Gypsogem into your desire mould and bubbles are easy to pop but tapping the mould (but this powder is not prone to them if mixed well). Also bang the mould a bit on the table to assist with any bubbles.
- Work quick once mixed as it will start to set. Let it cure for 15min, after this time, demould aand see the stunning creation.
- Note when demoulding it will be warm.
- When it comes to Gypsogem, curing is a crucial process that significantly impacts its final strength and durability. It recommended to leave to cure for 24-48 hours for stronger strength.
- When working with black Gypsogem powder, it’s important to note that its special pigments can require additional water and may stain moulds. To prevent this, it’s advisable to clean the moulds immediately after use. Using rubbing alcohol is an effective way to remove any residual pigment. Alternatively, maintaining separate sets of moulds for black and lighter, non-pigmented colours can help avoid cross-contamination and preserve the quality of your casts.
- The measurements and guidelines provided are just starting points; as you gain experience, you’ll find ways to tweak and improve upon them. Trust your instincts and don’t be afraid to try new things. Your personal touch can transform a good project into something truly unique and tailored to your own style and preferences. Happy experimenting!
