Plastisol Heat Resistant Borosilicate Cup (250ml)

Product detailed description

When you start heating plastisol, you quickly learn that the container matters. This one is PYREX — one of the best high-heat borosilicate options out there. The thick-wall build holds temperature for a long time, you get a clean pouring spout, a solid handle, and a clear red scale — so your tests, small batches and pours stay under control.

250 ml is the perfect size for “precision work”: clear-coat lamination for soft baits up to 10 cm, small recipe tests, mixing pigments and additives, and quick micro-batches. It heats fast, reacts fast, and keeps the workflow clean.

Soft bait lamination (the 3D finish)

Lamination is a simple clear surface layer: dip the finished bait body (with glued eyes) into heated plastisol for a moment and let it drip off. You end up with a clear “skin” that adds depth, gloss and a 3D look.

Why borosilicate (and why it surprises people)

Borosilicate (Pyrex-type) is designed for high heat and thermal shock — exactly what can crack regular glass in a workshop. Commonly stated ranges for borosilicate are roughly -40 to +300 °C and thermal shock resistance around 220 °C (indicative values; always follow the specific product specs).

A gentle note about PYREX (extra-soft plastisols)

Because PYREX holds heat so well, very thin plastisols like extra soft / trout can be easier to overheat if you rush it. The fix is simple: heat in shorter steps, stir more often, and watch the consistency (a thermometer helps).
If you prefer a lighter jug that doesn’t retain heat as aggressively, Simax can be a great alternative in certain phases — different ergonomics, different feel.

Also fair to say: 250 ml is brilliant for lamination and tests, but it gets hot quickly and the smaller body can feel less comfortable for long hand-holding. Many makers like the 500 ml size for maximum comfort.

Which size to choose (real-world guide)

→ 250 ml: lamination up to 10 cm, tests, pigments and additives
→ 500 ml: everyday work + lamination (most universal, more comfort when dipping) up to 16 cm
→ 1000 ml: bigger batches, more molds, longer heat retention and enough reserve for lamination up to 25 cm
