Saerohands Natural Soap

The 20cm glass rod is a basic stirring implement used throughout soap making and cosmetic DIY. Glass rods are preferred over metal or plastic for stirring lye solutions and fragile emulsions because glass is chemically inert - it does not react with lye, acids, or fragrance oils. A 20cm length works well for beakers up to 500ml; for the 1000ml glass beaker, a longer rod would feel more comfortable, but the 20cm version is still functional if you work close to the rim.

Glass rods are also easy to clean and do not absorb color or fragrance from pigmented or scented batches. For cold-process soap making, a glass rod is used to stir the lye solution as it cools, and for melt-and-pour soap, it is used to stir in additives once the base has melted. Clean thoroughly between uses with hot water and mild dish soap.

Two reagent spoons appear in the SAEROHANDS Natural Soap lineup: a 30cm standard spoon and a 21.6cm cow-shaped spoon. Reagent spoons - also called laboratory or sampling spoons - have a small, narrow bowl that holds a precise amount of material per scoop. They are used in soap making for transferring small amounts of fragrance oils, colorants, or dry additives without spilling or over-measuring.

The 30cm length keeps your hand away from the batch when working with hot materials or lye, which is a safety advantage. The 21.6cm cow-shaped version is slightly shorter and has a novelty design, making it popular for people who document their soap-making process visually. Functionally, both spoons do the same job; the choice is mainly personal preference and batch scale - the longer 30cm spoon suits deeper beakers and larger work areas.

Glass beakers in the SAEROHANDS lineup come in three sizes: 100ml, 250ml, and 1000ml. Each size covers a different part of the soap-making workflow. The 100ml beaker is for measuring and mixing small quantities of fragrance oils, colorants, or botanical infusions that are added to the main batch in small volumes. The 250ml is a mid-size general-purpose beaker for intermediate measurements and for mixing small test batches.

The 1000ml glass beaker is the batch-scale vessel - large enough to hold the full oil phase or lye solution for a standard single-pound soap batch. Glass beakers are heat-resistant, which matters when measuring hot oils or working with freshly mixed lye solution (which heats up on its own as sodium hydroxide dissolves). The graduated markings on glass beakers also let you measure by volume directly in the vessel without a separate scale.

PP (polypropylene) plastic beakers in the SAEROHANDS line come in 250ml and 500ml sizes. PP is lye-safe, which is the critical property for soap making: polyethylene and polypropylene both tolerate contact with sodium hydroxide solution, while other plastics such as polystyrene can crack or leach. PP beakers are lighter than glass, do not shatter if dropped, and cost less, which makes them practical for steps where you need multiple vessels running simultaneously.

Use PP plastic beakers for measuring and holding the lye solution if you prefer a shatterproof option, or for holding premeasured ingredient batches before adding them to the main mix. The 250ml size covers oil additives and fragrance blends; the 500ml handles larger intermediate volumes. For any step involving heat above roughly 80°C (175°F), check the beaker's stated temperature limit before use - PP is heat-tolerant within a range, but sustained high heat can warp plastic beakers.

The Alcohol Glass Thermometer in the SAEROHANDS lineup is a lab-style glass thermometer for monitoring temperatures during soap making. In cold-process soap, both the oil phase and the lye solution need to be brought to compatible temperatures - typically between 40°C and 50°C - before combining them. Accurate temperature readings reduce the chance of soap seizing or not reaching trace correctly.

Glass alcohol thermometers are not digital, which means they require no batteries and are straightforward to read and calibrate. The main limitation is that glass thermometers are fragile; handle them carefully when measuring in narrow beakers or when the batch is actively mixing. An alcohol thermometer (as opposed to mercury) is the safer lab option for home use in the event of breakage. Clean after each use and store in a protective sleeve or tube if possible.

The 3ml plastic dropper pack (10 pieces) is used for adding very small, controlled volumes of liquid ingredients: fragrance oils, liquid colorants, vitamin E oil, or other additives that are measured in drops or fractions of a milliliter. A 3ml capacity per dropper covers most additive measurements in single-batch soap making without needing to refill between steps.

The 10-piece pack means you can use a separate dropper for each ingredient in a batch without cross-contaminating fragrance or colorant between steps, then dispose of or clean them between uses. Plastic droppers are not suitable for concentrated lye solution - use glass or PP for that - but they work well for everything else in the fragrance and colorant workflow. They are also handy for cosmetic DIY projects beyond soap: toners, serums, and facial oil blends where you are adding a few drops of an active at a time.

The SAEROHANDS Natural Soap collection gives you both glass and plastic options for beakers. The practical guide: use glass where heat resistance or chemical inertness matters most - the glass rod for stirring lye, glass beakers for the lye solution step and for heat-sensitive measurements. Use PP plastic where you want a shatterproof vessel and heat stays moderate - mixing colorants, holding premeasured fragrance oils, or keeping intermediate volumes ready before adding them to the main batch.

Building a set that includes both glass (100ml and 250ml for small measurements, 1000ml for main batch steps) and plastic (250ml and 500ml for holding ingredients in parallel) gives you enough vessels to run a multi-step cold-process batch without stopping to clean between each measurement. The reagent spoons, glass rod, thermometer, and dropper pack fill the remaining equipment gaps for a complete basic kit.
