What Is Borosilicate Glass And Why Is It Used For Dildos?

 If you’ve cringed at the thought of putting glass in your vagina, fair enough! When you think of “glass” you would typically think of a breakable water glass that smashes when dropped on the ground. 

So I’d love to start off by assuring you that glass dildos are not made out of the glass used to make the glasses you drink your kombucha out of or the glass in your window-frame. They are made of much stronger, more superior glass called Borosilicate glass. 

Borosilicate glass can be boiled without cracking and is created to be shatterproof. Like your Pyrex glass oven-proof cooking tray, your glass dildo is a solid piece of glass that can whitstand extreme temperatures - both cold and hot. 

Borosilicate glass is a non-toxic type of glass with silica and boron trioxide as the main glass-forming constituents and are known for having very low coefficients of thermal expansion, making them more resistant to thermal shock than any other common glass. Which is IDEAL for dildo use, right??

Why Have YPP Glass Dildos Been Annealed?

Our glass products have all been annealed, which takes more time (and money) than regular cheap glass dildos from Amazon. The process known as “annealing” makes the dildo more resistant to internal stress (kind of like meditation for humans!?). Although annealed glass can’t guarantee it won’t break on a hard surface, it’s definitely crucial in it being the safest glass to use internally - anally and vaginally. 

Our glass dildos are by far the highest quality on the market because they have all been annealed in an oven at 530 degrees which guarantees there will be no defects. After annealing, the glass will be more solid and harder than non-annealed toys. 

How Are Glass Dildos Body-Safe?

There are several factors to a dildo being "body-safe". In relation to glass dildos, it means that they are non-porous, don't contain toxic chemical ingredients like pthalates and are not designed in an unsafe manner that render them inappropriate for sexual play, such as an anal toy that does not have a flared base.

Hypoallergenic basically means it won't cause allergies or sensitivities, and odor resistance means it won't hold scents or smells after it's been sterilised or cleaned, unlike some jelly, plastic or silicon toys. 

Could A Glass Wand Break Inside Me?

Absolutely not. This thought is something nightmares are made of, but it is impossible if you’re using a high-quality solid dildo made of annealed borosilicate glass. Even cheaper glass dildos won’t break inside of you, however if you drop them on the ground they will break, so if you want your dildo to last forever spend the extra $50! 

It My Glass Dildo Break If I Drop It On The Floor?

Maybe, maybe not. It would depend on what material the floor is made of and where exactly the glass wand drops. If there is a thinner ‘weak’ point in the dildo, it could potentially break. If it drops on tiles or concrete, it is more likely to break than on wood, carpet or plastic. 

If you do drop your toy and it cracks, please don't use it internally or try to fix it with superglue. It's best to throw it in the bin (recycle please) and invest in a new one. 

Your crystal pleasure wand will 100% break if you drop it on the floor, however glass dildos are much more resilient and sturdy! 

How To Clean Your Glass Dildo

Before embarking on your pleasure journey with your new Sacred Squirter, we highly recommend reading through our 101 guide on how to clean your sex toys.

For glass dildos we recommend using hot water with your favourite toy cleaner (our natural cleaner spray even has crystal chips in it for good juju!) or even something like apple cider vinegar or eucalyptus oil or even soapy water. Technically you can put your used glass dildo in the dishwasher, but let’s be honest your dishwasher is for cutlery and crockery not dildos, but no judgement! 

What Lubricant Can You Use With Glass Dildos?

You haven't experienced epic self pleasure until you've inserted a warm glass dildo lathered in your favourite lubricant. *gasps*

The good news is that all our glass and crystal dildos are compatible with all lubricants and oils. It just comes down to preference! We highly recommend @YinnBody organic lubricants because they are 100% natural, but also because the branding is on point and something you will want as a permanent feature on your bed side table.

 Since glass wands are hard, it means they are the perfect accompaniment for vaginal dearmouring and dilating. So if you're someone who experiences pelvic floor tension, vaginismus or trauma in this space, creating time to practice this can assist in the healing process.

Glass Dildos And Temperature Responsiveness 

Have you ever had an ice cube used on you during sensory play? It feels exquisite and lots of fun to explore different temperatures and sensory stimulation inside your genitals. 

Temperature responsiveness means it can be heated or cooled and can withstand extreme temperatures. One thing I love about glass toys is that initially it feels cold when inserted and then your body heat transfers to the glass dildo making it warm!

The amazing thing about high-quality glass is that it can be put in the freezer/fridge or warm up in the microwave or under hot running water and it insulates and holds to the temperature for a long time! Real borosilicate glass is heat and cold proof (up to 572° F and down to -40° F), so you do not need to worry about it cracking or exploding.

This goes without saying to be VERY cautious with the temperature of your dildo being too hot or too cold. A dildo that’s been kept in the freezer may stick to the skin or crack if thawed too quickly. 

All the colours used in our dildo designs are 100% body safe and won’t leach out in boiling hot water. 

Our Glass Dildos Are Hand-Designed & Hand-Crafted

All YPP dildos are unique and have been hand-sketched and designed by founder, Rosie Rees. Even if there's a similar product on the market, the team will change this by 30% to be more sexually ergonomic and in alignment with the Yoni Pleasure Palace brand, which is built on a foundation of slow self pleasure and female sexual education. All the glass dildos are hand-blown in small batches, meaning each wand is slightly unique and there are no two dildos are exactly the same.

Often dildo designs we've formulated and hand-crafted go viral (...Cervix Serpent & Sacred Squirter) and are replicated by other brands. We celebrate diversity and originality in the product creationion process and although we don't condone copy cats, we are also flattered to be imitated!

Other Amazing Benefits of Using A Glass Dildo:

  • It’s 100% body safe to use sexually 
  • It’s hypoallergenic (AKA you won’t have an allergic reaction to it).
  • It’s odor resistance (it will never smell unlike some cheap rubber to plastic toxic toys)
  • It’s able to be sterilised between partners and uses
  • It’s non-porous and compatible with any lubricant
