These popular moulds are suitable for use with soap, soy wax, clay, plaster, chocolate and bath bombs, and bath and massage melts! Let your imagination run wild!
Melt & Pour Soaping is trouble free with Milky Way Moulds. It is simply: melt, colour, fragrance and pour! Ensure that the soap is completely set and cold before trying to unmould. We suggest washing the mould prior to first use.
Keeping Cold Process Soap properly insulated is important when pouring into individual cavity moulds. This helps gel which makes a harder bar of soap – and one that is easier to unmould.
Pour Temperatures: These moulds can tolerate wax and soap temperatures of 57 - 60ºC. If you're concerned about warping, set the moulds in a shallow cold water bath for hot-temperature pours. Heat loss with Cold Process Soap can be a problem due to a large surface area relative to a small volume of soap. This heat loss can retard saponification (this is why you need to insulate small moulds extra well). One solution to this potential problem is an elevated pour temperature in the region of 46 - 51ºC. Another method involves pre-cooked soap – this is hot process Soapmaking. The third alternative is to contain the moulds inside an old Esky, or under a couple of layers of an old doona or sleeping bag.
Transparent Soap Note: Opaque Cold Process Soap considerations don't apply to Transparent Soap since its neutral when poured. Transparent soaps also lack "stickiness," so there shouldn't be any problem unmoulding them.
Pour Time: When filling many cavities, realistically consider just how much working time you have before your soap begins to thicken beyond the "easy-pour" state. Dividing soap up into smaller portions for different colours and fragrances will slow you down; some fragrances and essential oils will speed the thickening of CP (trace). If this is the case, think about making smaller batches. If your soap does thicken before all the cavities are filled, spoon the soap in and tap the moulds lightly on the counter top. The clear plastic will allow you to see if any air bubbles remain on the mould’s detail surface. We usually pour at least one tray of Individual cavity moulds out of each larger batch pour. That way over time, we have quite a range of beautiful, single cavity moulded soaps for special gifts.
Cold Process Soap high in soft oils such as Olive, Canola, Avocado, Safflower, etc. can be a bit sticky, and therefore may unmould with more difficulty than firmer soaps high in Palm Oil or Coconut. These softer soaps will unmould if placed in the freezer for 1 hour. If you like this choice of fixed oils in your Cold Process Soap the addition of Sodium Lactate Plus will help unmoulding considerably.
Cleaning the Moulds: Use warm tap water and soap or dish washing liquid. If the moulds have been used for soapmaking simply soak in warm water for a half hour or so). Hot water, including dishwasher water, may warp the plastic.
Unmoulding: Avoid man-handling the moulds when releasing contents or you may crack your mould
For Melt & Pour Soap:
Firstly, ensure your soap is completely solid and COLD – this means completely set at room temperature. If you are trying to take still warm soap from a mould, you will run into problems. Make sure the soap has set completely - the temperature and hardness are the surest guides. The best way to remove Melt & Pour Soap from the mould is to take a fairly thin, flexible spatula and simply run this around the inside of the mould walls - this allows some air to be introduced between the wall of the mould and the soap. Then turn the mould upside down and run your thumbs from the outside of the mould towards the centre, exerting gentle, but firm pressure. The soap will simply pop out onto the bench, if proving a little stubborn, a gentle tap on the work bench will usually do the trick.
The size of the mould, pouring temperature of soap and ambient room temperature will determine set up time. Allow 1 hour minimum before attempting to unmould single bars. If using a loaf, slab or log mould, leave overnight before attempting to unmould. If you try and unmould too soon, you’ll eventually live to regret your impatience!
If you experience any problems, half an hour in the refrigerator will help, but this isn’t recommended as a routine way of setting your soap. If you have been in a hurry, and chilled the soap, allow the mould to return to room temperature before attempting to unmould – this avoids damage to the mould. Using the freezer increases the probability of sweating.
For Cold Processed Soap:
Gelling Cold Processed Soap will make the bar harder, so this is helpful. Before attempting to unmould, run a plastic spatula or blunt knife around the inside walls of the mould. This allows air to enter. Turn the mould over and firmly move your thumbs from the outside of the the cavity with firm pressure to the centre of the mould. This is normally sufficient for unmoulding.
If you have any difficulties with unmoulding allow the soap to sit in the mould up to 24 hours - particularly if you are new to Cold Process Soaping.
If your Cold Process Soap is stuck, place the mould in your freezer for approximately 1 hour which should be sufficient but if left longer it won’t matter as Cold Process Soap is so robust. Allow the mould a few minutes at room temperature before unmoulding – if you can’t wait, run a little warm water over the mould, like unmoulding a jelly. Invert the mould, run your thumbs gently but firmly from the outside of the mould to the centre, you will see the air move across the clear moulds and a slight tap and the soap is out.
If Cold Process soap is allowed to remain in the moulds for 12 - 24 hours after cooling down, it releases much more easily than unmoulding it immediately upon cooling. (During this extra time the soap is shrinking ) Gelling Cold Process Soap also helps unmoulding the soap.
Remember: If you try and release the soap from the moulds by force, especially if you use the freezer, you will damage and possibly crack the mould. Moulds are not designed to withstand this sort of treatment.
Using the freezer method consistently to unmould may shorten the life of your moulds, so use this method as infrequently as possible.
For Soy Tarts and Massage Melts:
The recommended pour temperature for EcoSoya PB is 57°C. We have never experienced any issue unmoulding soy tarts!
If washing moulds after making Soy Wax Melts or Bath Melts you may need to use a little more detergent (because it's oil) and use a hotter water temperature, but do not leave the mould submerged for extended periods.
