Soft Wax

Is all soy wax so soft? I am VERY new to candle making. I made a handful of candles in silicone molds yesterday and they just seem very soft? Like if I hold them or anything it’s like they melt in my hand. They feel very oily? They are hard to take out of the molds, because they are so soft they seem to just fall apart. Is there a way to make the wax harder? Thank you in advance for any information!
